IBER004 - Iberis sempervirens 'Whiteout' (Kieft Seeds)

IBER005 - Iberis ABSOLUTELY AMETHYST® is said to be the first lavender or lilac-toned perennial clone of the genus. Amethyst and lavender it will be...the claimed "purple" is for people with no sense of color. To that I say, I and many other people had this shade from Iberis gibraltarica decades ago and mine was hardy for some years in USDA 4 of upstate, Syracuse, New York of all rigorous places to test perennial hardiness. This is a fine plant, superior to random I.gib's but it is vastly a rewrite of history to call it a first in the lavender perennial class. Best in class...maybe..one of a few today (2014) but definately not first. Now we add in the note that Monrovia, the big powerhouse, among others, says their I. sempervirens PINK ICE™ is the first pink perennial cultivar, a close shade in some lights and very lavender in bud.  Isn't it likely that their clone too borrowed a rosy gene or two from I. gibraltarica or less likely the popular but sometime semi-hardy I. umbellata. Also the originator's claim for ABSOLUTELY AMETHYST that it belongs to the non-existant species Iberis hybrida should have challenged by the US Patent Office from minute one. Patenting a plant in a species that does not exist might well be grounds for revision or rejection, me thinks. If it's not pure I. gibraltarica (and I suspect it would be a cross to I. semperviren given the head width)...it's a nice find and surely a useful item. The University of Tennessee, an elite horticulture group, rated it 2.0 overall out of 5.0 so it may not be for everyone. Give it a whirl for the pretty, not purple, tones. Just forget the hype and spin and bad data. Click image. The above image is NOT free for reuse under the OROC Data Sharing program.

ILEX008 -  opaca 'Winter Sun' (Rare Find Nursery, Holly Ridge Nursery) - we are all used to red and some gold-berried American hollies but here's one of the few that bridge that gap with golden-orange to pale orange fruit colors.
ILEX009 -  vomitoria 'Lances Weeper' - vigorous, penduous. Based on JC Raulston Arboretum, accession #040566 in 2004.
ILEX010 -  verticillata 'Firestorm' - see American Holly Society Registration
ILEX011 -  'Baltimore Blaze' - see American Holly Society Registration
ILEX012 - Ilex x attenuata 'Blackwater' - 15 ft. tall x 8-10 ft. wide, vigorous, open branched unless heavily pruned, best trained in conical form.  Stems purplish at first, later grayish-brown.  Seedling of 'East Palatka' but resembling 'Foster No. 1', having more drought and soil saturation tolerance but it. Female clone, fruit heavily. Panhandlegrowers.com, accessed 5.9.2015.
ILEX013 - Ilex cassine 'Dodds Yellow' - 12-15 ft. tall x 8 ft. wide, open, erect. Leaves dark green, toothed. Fruit yellow, showy. Tom Dodd. Panhandlegrowers.com, accessed 5.9.2015.
ILEX014 -  Ilex cassine 'Tensaw' - 15-20 ft. tall x 10-15 ft. wide, more heavily branched than some forms, narrowly to moderate pyramidal, crown often rounded with age. Leaves light green, very ovate, darker green with maturity. Panhandlegrowers.com, accessed 5.9.2015.
ILEX015 - Ilex vomitoria 'Miss Allentown' - 10 ft. tall x 4 ft. wide, dense, multi-trunked, narrower, very heavily branched. Leaves smaller, dark green. Fruit small, abundant. female clone. Selected by PGI. Panhandlegrowers.com, accessed 5.9.2015.
ILEX016 - Ilex vomitoria 'South Harbour' - 12-14 ft. tall x wide, very dense, wider as most species form. Leaves dark green, slightly purple in new tips. Selected by PGI from Little Sabine Bay, Pensacola Beach, Florida, USA. Panhandlegrowers.com, accessed 5.9.2015.
ILEX017 - Ilex opaca 'Brotzmans Male' - proven male pollinator. Selected by Brotzman's Nursery, Ohio, USA.
ILEX018 - Ilex x meserveae 'Little Gloss' - 50-150cm tall x 50-100cm wide, slow, dense, shruybby.  Leaves bright medium green becoming dark green, very glossy, the name suggesting a little plant with gloss not a low amount of luster. Male clone, no fruit, good pollinator. Bred by K. Hibbers, Kranenburg, Germany.
ILEX019 - Ilex maximowicziana var. kanehirae  IMPALA® (Ilex mutchagara hort.) - 1.5-2.5m tall x 0.5-1.0m wide, erect. Stems purplish, semi-showy. Foliage much as Ilex crenata but a sharper apex in general, 2-3 cm long, elliptic, serrulate, light green bnecoming darker. USDA 6. One reference states "it's correct Latin name is faqr too long and a bit complicated to pronounce and spell, hence its modern trade nmae IMPALA holly". Thus one might propose this a mere rename of the species but in the course of rooting this material it invariably becomes a popular clone of the species, and surely not it's sole representation worldwide, and may be regarded as a typical name names.First seen by us at havlis.cz, accessed 5.16.2015.
ILEX020 - Ilex vomitoria 'Scarlet's Peak' - 20 ft. tall x 3 ft. wide, fastigiate to narrowly columnar, very dense, much narrower than 'Will Flemming', the current and popular evaluation standard for narrow Yaupons, a  clone which often splits and sends out odd arms after being injured or flopping in portions in a very ungraceful manner, requiring regular pruning, this new clone with branches also much stronger than this standard. Leaves smaller than species typica (23-25mm long x 9.5-12mm wide), very dark green. Fruit red, sometimes numerous (20-35 per later branch), a female clone, not a male fruitless clone as 'Will Flemming'. USDA 7b-8 hardiness. Said to be replacement for the conferous Italian cypress by some growers. US Plant Patent #20581 to Daniel Batson as corss of unnamed seedlings, selected 2005, patent assigned to Unique Plants Inc.

Indigofera

Indigofera pseudotinctoria 'Rose Carpet' as seen here at the Raulston Arboretum is raised in shale flakes and soil under a common gravel, giving it perfect drainage and yet enough capacity to retain the needed moisture. This little ground cover is drought tolerant and pretty as any pink-clustered legume in this improved, rich clonal selection. It passes the strict Tony Avent test as staying low, neat, never invasive, and yet with miniature Wisteria-like flowers. It is a USDA 6a (Missouri B.G. says USDA 5) plant but it will likely have potential as a nice big container woody plant for cascading and for as a long-term conservatory flowering groundcover. It will die back to conserve it's resources (as with many legume) and is also slow to leaf out in spring - don't leave it for dead says Tony...Avent I mena...not Sorpano. Please click the image.

IRES001 - Iresine herbstii NEON PINK "Herbie53' - 40cm tall x wide, very compact, needing less pruning than common pink-veined clones. Leaves suborbicular, short, apex often botched to bifid, generaly obtuse  to broadly acute,  rich reddish-purple to dark burgundy, heavily veined a glowingt shade of hot pink or neon pink, this is a not like a common red clone with pink veins, the base color being very dark, blackish-purple at times.

Iresine herbstii 'Blazin' Lime' and it's redder, pink sister 'Blazin' Rose' are very much improved clones for both outdoor bedding and house plant use. The lovely mix of bright olive, cream, light yellow, near gold, forest green, and lime in this one is simply stunning. When you add the rosy-red stems, high vigor, and larger lamina, this is far superior to the older, gold-veined material. Please click the image...we don't use tiny, useless thumbnails on this site!

It is also strong enough to make a summer outdoor treat if overwintered in a northern greenhouse.

JUNI009 - Juniperus squamata 'Green Star' - Girardnuseries.com, 2014
JUNI010 - Juniperus STAR POWER™ 'J.N. Select Blue' - 6-7 ft. tall when similar J. chinensis 'Ames', 'Iowa' and J. virginiana 'Caneartii' were just 4-5 t. tall at the same age, hence very vigorous, narrow upright, narrowly ovoid to narrowly pyramidal, dense,  rich silvery blue. Leaves highly-divergent, similar to J. communis and juvenile foliage of J. chinensis, many star-shaped green leaves with star-shaped tips appearing, bright stomatal bands very apparent on the upperside.  Michael Yanny, 1998 found as possible cross of J. communis x J. chinensis, introduced johnsonsnursery.com, Wisconsin. The images are not consistant with ordinary juvenile J. chinensis forms and so a cross to J. communis is likely.
Li: http://www.deckersnursery.com/wp-content/uploads/2012/01/JNInc_StarPowerFlyer.pdf
JUNI011 - Juniperus squamata LITTLE JOANNA® - much as (Meyeri Group) 'Blue Carpet' but even more compact, slower, low-spreading and not tufted nor mounded as 'Blue Star' which is much more vertical and decumbent.
Eur. CPVO PBR to Boomkwekerijen Gebr. Visser, Netherland, "active: under procedure'  when accessed 5.2.2015. This appears to be best available image of it, given the originator (Visser) has no posts (5.2.2015):
http://www.newplants.nl/typo3temp/pics/0173415259.jpg
JUNI012 - Juniperus squamata 'Tropical Blue' - very dense, dwarf, compact-mounded, similar to 'Blue Star' but a more silvery-blue tone, sometimes with aqua notes (hence "tropical"), leaves shorter and sometimes slightly twisted about the stem but only moderatley so, not a contorted clone but with nice subtle, irregular leaf twist. Older plants tend to have outwardly  cascading shoots than 'Blue Star' but is not a wide-spreading clone in general.
PENDING - Juniperus rigida var. conferta 'Golden Wings' - Habit loosely procumbent to low, irregular decumbent , much as species in Western gardens. Leaves medium green, to pale blush-green,  in the foliage mass variegated with a scattered chimera in light to  medium yellow, 10-25% of branches and foliage mass. It appears identical to 'Sunsplash' from Brookside Gardens and of US and could be either a parallel mutation or rename. The use of this appears from web searches to concentrate mostly with Polish nurseries (may 2015).
JUNI013 - Juniperus x media 'Blue Chiffon' -  elegantly spreading, some limbs erect, tufted long limbs, reminds us of a larger, arching J. sabina 'Blue Tam' overall. Leaves mostly divergent or adult type, bluish-green to light blue. Bluehorizonnurery.com, their own selection, accessed 6.2.2015.
JUNI014 - Juniperus horizontalis 'Copper Harbor' - as 'Bar Harbor' but newer shoots light to medium yellow, older foliage blue and contrasting, due to the parent  culitvar's height differences, taller than 'Wiltonii' gold sports and yet shorter than LIMEGLOW, winter coloration a lovely mix of copper, orange, blue, bronze, and gold tones. bluehorizonnursery.com, their sport, accessed 6.2.2015
JUNI015 - Juniperus procumbens 'Peve Spikkel' - compact, typical of the 'Nana' or slower clones in form. Foliage mass mottled 40% of surface in light yellow to cream, most variegated sections large and covering many secondary branchlets.

Juniperus virginiana 'High Schoals' - informally pyramidal, nice lacy look due to long shoot tips and good vigor, not overly dense yet neat, reliable green winter color, female clone and known to produce showy blue cones. Or: Ray Tate found outside Watkinsville, Georgia. In: www.boldspring.com, accessed 2.28/2016

Juniperus virginiana 'Greenbelt' - broadly pyramidal, bright rich green colors, developed for ease of transplanting, and we have seen as many as 50% of redcedar plantings in commercial settings fail. In: www.boldspring.com, accessed 2.28/2016

Juniperus scopulorum 'Woodward' - 20 ft. tall x 2-4 ft. wide, fastigiate, handling "snow loads with grace". Foliage dark green turning more greyish-blue in winter. It appears to be paler than 'Spartan' which while usually sold as a Juniperus chinensis is actually a J. scopulorum when the foliage and cones are subject to taxonomic scrutiny. A comparison of the two is warranted.

The Golden Maymont Junipers: 'Aurea','Schottii', and 'Maymont Gold' by Larry Hatch. What is or was 'Maymont Gold' and a second gold juniper on the grand estate grounds with taxonomy clarified.

Juniperus chinensis -

Review of Juniperus chinensis by P.J. vanMelle (book, Amazon) - an American decided to stir up the world of conifer taxonomy and wrote from experience and a very extensive knowledge of both herbarium specimens and living plants. He reclassified most of the Chinese junipers and determined with much evidence those taxa had been misunderstood before, and that the Pfitzer types were indeed  a hybrid. He was a scientist without credential and so upset the establishment to no end. His upstart, American murseryman  approach did not suite European experts well and recently they got a sort of revenge by determining his J. x media was a homonyn of J. media named earlier by a Russian botanist in a journal not internatinally distributed or known (a requirement for a valid species name) and so highly  dubuious and vague it is a rejected nomen confusum. That Euro-centric nonsense is so petty, unfounded, and ridiculous it is shame people still believe the case that is not so much weak as non-existant. VanMelle's breathrough, controversial monograph is still available from time to time at $25-100. I have read it four times and some parts many more times.




Juniperus chinensis 'Shoosmith' at Maymont Gardens in Richmond, Virginia, one of the oldest known examples (not the orignal) and planted by the nurseryman's family with a nice commenorative sign. It is one of the best green Chinese junipers out there, tight and tufty, a pleasantly irregular shape, mostly free of sharp needles (many fewer at least), very bright, verdant green at times and yet dark from a distance. A bonus second picture below from cross-town Lewis Ginter Botanical Garden shows the amazingly prolific coning, an endless pile of waxy blue "berries" (actually female strobili), on a very young plant (then just 4 feet tall) and the bright colors of the thicker foliage. I am told it will cone-up well as a dense, tufty bonsai subject. There are more pictures on the member's side. Click both images if you will.

An Investigation of the Cultivated Kalanchoe diagremontiana Group, with a Checklist of Cultivars by Shaw (Hanburyana 3: 17-79 (2008))


Kalanchoe fedtschenkoi 'Rosy Dawn' is one of two clones sold as 'Variegata', the other being the much more common pink-margined to cream-margined clone, this second one also called 'Marginata' and 'Cream Scallops'. The name 'Variegata' is not established for this gold-centered sport with it's cream-yellow to lime-green hues and lots of coral to carmine shading. The common name 'Rosy Dawn' has been used for it and thus makes an appropriate and valid cultivar name with the lack of documentation on the other names. Click image.

Kerria
16 cultivars



KERR001 - Kerria japonica 'Chiba Gold' gives interest even when this fine, flowering species is not in gold bloom. In fact, it's true gold flowers contrast it bit poorly and awkwardly with the limey-chartreuse and pale lemon tones of the leaves. It is best as a misty blast of pale coloration in an other dark or blue border. It's not among the finest gold-leaved shrubs but it is different, fairly new, and rare. Click image to enlarge. Above image not part of OROC Data Sharing.

Kerria japonica CAT'S EYE™ 'Shandale' - 2-3 ft. tall, flowers large, showy, golden-yellow as parent 'Shannon', leaves thinly margined white.  Or, in: http://springmeadownursery.com/plants_details.php?id=52240, accessed 12.27.2015, as sport of 'Shannon'.

KOEL003- Koelreuteria paniculata 'Beachmaster' - see notes below. Image and notes n ot pafrt of OROC Data Sharing.
------end of OROC Data Sharing


KOEL003- Koelreuteria paniculata 'Beachmaster', an elite, useful seedling named by the late Dr. J.C. Raulston of North Carolina State University, completely floriferous and with wide, nicely structured panicles (many seedlings are less fireworks-shaped) with a truly reduced, perhaps 45-60% species typical dimensions, not overly compact nor extreme; just right to my sensibilities at least. This one plant at JC's own garden at the university may not be the original (planted 1999 after his death) but is surely the best example on record anywhere. My images date from 2003 when my original RAW and JPG were filed away and I do know, being there at the time, Dr. Raulston distributed this plant to the trade and collectors in the 1990's. 'Beachmaster' must be spelled as one word in the originator's choice.  It comes from a smaller, beach-based or maritime population in Korea and 'Woodlander's Low Form' is from similar stock but the Woodlander's Nursery website  (accessed 11.30.2014) suggests it might be the same as 'Beachmaster'.  I read an academic article about a guy developing new golden-rains and said he hoped to exploit Korean material for useful, dwarf forms. When I wrote and included a link to this plant, saying nicely we already have one proven named clone and what did he think of it, he replied with distrain that this was not what they were hoping to get and had higher aspirations. Reallyt? That man was a typical snob Ph.D. with a not-invented-here and got-caught-not-knowing-the-literature syndrome. Really? I pity the fool for 'Beachmaster' is the finest dwarf, flowering tree of it's kind and there is very little to change or improve about it. Needless to say, no one has heard much since from that pompous moron with no respect for great woody plant scholars and brilliant cultivar developers like Raulston, Dirr, Hasskelkus, Egolf, Herman, and Santamour that came before him.

Lactuca
satica
(ornamental lettuce)


The new and old varieties of lettuce can be very ornamental, especially if alternated in blocks or rows of green vs. bronze vs. red vs. mottled and so on. The ornamental, edible garden is not a new thing as lettuce, chard, cabbage, basil, and many other vari-colored crops have been grown this way for centuries. Don't expect a sunny, hot, barely watered bed in your front yard to look pretty but in your well-tended veggie plantings, you will get more the ordinary effect with a little of a design eye and some planning. The newer cultivars like 'Red Velvet' are more soldly colored red, a darker and more glossy presentation, textured to reflect lots of interesting light from somber reds to silver and white, and alot of pink tones if you study this picture a bit pixel for pixel.

Leiophyllum
Leptospermum
Lespediza


Lespedeza thunbergii 'Spilt Milk' was offered for some time (and still is) as 'Variegata', a name not published prior to 1959, and thus not valid as a cultvar. We do know this very highly marked and glorious legume came from Japan and very little else is known. Being a legume it has drought resistance, durability, and a good density in the foliage as most of them do - I sure hope plant genus stereotypes never become an HR or civil rights issue. As most of us know, variegated plants extend the beauty of a plant (hopefully) well before and after their blooming period. Be warned that this clone is not as floriferous or refined for flower color as the other cultivars and I cannot recall seeing 'Spilt Milk' too impressive in the repro state. But who cares really? And who among us should or would, after all, cry about spilt milk? The foliage is more than enough here. Sorry, my framed Picasso does not come with a USB port and is definately not iPhone ready. And who should worry about that either?  Click on image.

Liquidambar

'Worpleston' - frankly most people in the US where the species is native have n'tfigured out this British thing from their literature. Pretty much every sweetrgum glows in the woods. This video shows a bright magenta-red fall color that explains it's appeal for 6-8 weeks there - maybe.Not everything that glows in Ithaca glows in Cambridge.

LIQU004 - Liquidambar styraciflua 'Little Richard' - 4m tall, pyramidal, very compact, semi-dwarf to slower. Leaves rich red, sometimes with orange in fall, smaller than species typical, often more narrowly lobed and more coarsely dentate when young. Thought to be of Australian origin.
LIQUI005 - Liquidambar styraciflua 'Summer Storm' - leaves blackish in late summer, remaining so into fall with inner, shaded blades in yellow to red shades
LIQU006 - Liquidambar styraciflua MILESTONE™ - 10-20 ft. tall x 6-8 ft. wide, semi-dwarf, subglose to short ovoid. Fruit absent (fruitless). Warren County Nursery.
LIQU007 - Liquidamabar styraciflua 'Gold Beacon' - Habit slightly slower than species typical. Leaves light green at first, maturing to light yellow to golden-yellow, remaining so all summer, apparently the reverse of 'Shocking Gold' aka 'Shock Gold' which is more yellow becoming green, fall colors red to orange, hence not an anthocyanin deficient sport as many gold trees. Selected by Charles Allen, Green Biz Nursery, Fayetteville, NC USA.  heritageseedlings.com, accessed 5.10.2015, asked by originator to market this for him. It is also sold by Forest Farm and Buchholz in 2015.

Forestfarm.com, accessed 5.11.2015. We found one Aussie grower (Kigi Gowers) in 2015 listing 11 year old stock so it must be at least that old.
LIQUI009 - Liquidambar styraciflua 'Savill Torch' - intense, reliable shades of red, orange, and gold in fall compared to other plants nearby.  Based on a notable tree at Savill Garden, Windsopr Great Park, UK as seedling c. 1930-40's. It was removed after damage in 2002 but already grafted and now available in the European trade, not yet seen in US cataogs (May 2015).

Loropetalum

60 cultivars



LORO001 - Loropetalum chinense var. chinense 'Tokyo Weeping' - 4-5 ft. tall x 4-6 ft., weeping to low-spreading, best raised as a high-grafted lant unless you wish a low, procumbent creeper or mound. Leaves medium green, not generally dark as new cultivars. Flowers creamy-white, fairly typical of species in tone and abundance. Click image above to enlarge. Above image not part or OROC Data Sharing.

LORO002 - Loropetalum chinense var. rubrum PURPLE PIXIE®. This is almost certainly the best of the low, very dark purple mounds and spreaders (this November 2014 at least) in terms of long-term density, tiny textured foliage, and persistance of the color into summer. The jury, at least for me, is out on the flowers as they seem to be sporadic and oddly distributed (magenta as with var. rubrum) on the foliage and not strictly necessary for a good display. The foliage and form are so near perfect here, though sufficiently variable plan t to plant not to be dumb, resemblant domes, flowers are just a glowing icing the already lovely cake. Here is a fine example of very useful Asian genetics made much more interesting and creatively lovely by persistant American breeding over these last 30 years or so since var. rubrum came to our shores.  Click image above to enlarge. Above image not part of OROC Data Sharing.
LORO003 - Loropetalum chinense var. rubrum 'Plum Glamorous' - shorter, compact. Leaves very dark plum-purple (187B). Fl;ower tepals bright plum-pink (RHS 187D), not magenta. Plant Growers Australia, intro. 2012, as cross of 'China Pink'  x 'Daybreak's Flame' in 2007.

Flowers tepals near white, fairly flat, narrowly obovate to broadly elliptic, rich lemon-mint scent of the spicy variety, Intro. Lewis Ginter Bot. Gard., Richmond, Virginia , USA c. 2012, bred by Bill Smith bef. 2010. To learn more about Bill's Magnolia breeding please view these videos:


MAGN004 - Magnolia grandifolia PURPAN® - very vigorous, said to be fastest clone known in Europe, up to 50cm a year growth once established.  Leaves thinnly rusty-tomentose below. Flowers 20-24cm wide, very well scented. While this name is new (about), it is said to be based on a vigorous clone from France known since 1735 in Toulouse, proving cold hardy over decades. The derives from a well-known French college of the same tree where and they feature the cultivar on their school website as Tree of the Year 2013. Their School of Agriculture registered the trademark. We currently believe this clone to more than a historical named stock (forbidden by the ICNCP)  from a famous tree of no horticultural merit. It's vigor and large flowers along with cold survival suggest it does have potential garden merit and is not merely a name fro a famous tree.
Magnolia virginiana GREEN MILE™ 'MVHH' - habit more erect, neater, evergreen, flowers most of summer. Leaves more glossy than some clones and appears more sharply acute as well. Or: Alex Neubauer, Hidden Hollow Nursery, Tennessee

It makes a massive tower to 30 feet tall (it is not the umbrella form) of intricate and lively contrasts of cream, pure white, dusky olive, lime-gray, and a glossy dark jade green, bordering on a solid forest green. This highly marked chimera is the discovery of the legendary Dr. J.C. Raulston whose taste in trees and things mottled or margined was remarkable.

MISC001 - Miscanthus sinensis 'Autumn Anthem' (Walters Gardens)
MISC002 - Miscanthus sinensis 'Oktoberfest' (Walters Gardens)
MISC003 - Miscanthus sinensis var. condensatus 'Luc-Andre LePage' - 5 ft. tall. Leaves margined yellow to 20% surface, midrib also silver, sometimes giving a tricolored look up close.  Flowers showy late (October), fall colors golden-yellow to brown.  Selected by Michel and Caty Le Damany of Pepinieres LePage, France. ISU 2014 Trials award.
MISC004 - Miscanthus sinensis 'Dread Locks' - 1.6m tall. Flower inflor. in dense clustered tubes, very erect overall, "springs" in one translation, well resembling the tightly braided dreadlocks hair style as small units but the panicle's overall  "hair style"  not pendulous or cascading  in general as found in the human form, colored rich purplish-violet or green tinged red, sometimes showing a "corrugated" or rippled effect or violet-red and silver along the branches. The added floral density and constriction results in heads often held within or just atop the foliage mass, not soaring above it like most modern cultivars. There is a Jamaican grass joke here somewhere but as a formal cultivar register we will of course resist that notion. Selected by Zillmer, intro. 2008.
MISC005 - Miscanthus sinensis 'Digestif' - 1.7-2.0m tall, sometime thinnly branched, hence a bit more natural than some modern compact material, rather relaxed in both flower and foliage compared to the super-dense, uptight modern clones.  Leaves narrower, reed-like, open mass, arching to pendulouis, not artificially dense in look,  a very rich green with the typical silver midrib.  Flower panicles reddish, fairly open and wide, dense in portion but overall very airy, a bit later in season. Selected by Zillmer, intro. 2008.

Nephrolepis exalata 'Tiger' is a curious chimera with lemon-chartreuse to lime tones etched and painted with elegance on an already rippled and serrulate (finely toothed) set of frond pinnae. This lovely thing, a bit subtle at times, was patented as 'Tiger Fern' but my taxonomic background tells me that common names like "fern" do not belong in a cultivar name under any circumstance. The Patent Office of the US and most lands will have no clue on that so I take the liberty of fixing this minor offense to fern nomenclature. This image should be enough to make most of us fall in love with this striking and also pragmatic interior plant. It is Nephrolepis-tough and yet a gentle charmer. Click image to enlarge.

OSMA005 - Osmanthus armatus 'Herkenrode' - highly incised, sharp teeth numerous. 4.12.2015

OSMA006 - Osmanthus heterophyllus 'Hariyama' ('Hari Yama') is a semi-dwarf, slightly tufty and spiky thing that will need a bit of guidance (pruning, staking) to form a suitably dense and put-together foliage mass with age. It is essentially a more compact, shorter-bladed version of the now popular 'Sasaba'. We now lament that the larger clone can get a bit large (8-10 feet) and in the wrong context is going to become a hostile, unforgiving nightmare full of a thousand green daggers; an accident waiting to happen for man, child, and beast alike. 'Hariyama' should be a more manageable, even if less extreme, alternative. Note my US quarter to show the scale of the leaf clusters. Click image to enlarge to 1250 pixels wide.

Oxalis regnellii CHARMIED® WINE is one of the brighter improvements on the old 'Atropurpurea' or purple shamrock. It does show a bit of a paler, more glowing violet-red magenta chevron but that is subtle in most conditions of cultue.
