Juniperus horizontalis LIME GLOW™ is a very heat tolerant sport of 'Youngstown' with yellow foliage which turns lime by summer. In winter it adds the familiar Andorra-type pigments to make it oddly gold, bronze, orange, pink, purple, and lime all at once. It is larger and taller than the gold sports of 'Wiltonii' and is generally more sun tolerant than them as well.

Juniperus virginiana BLUE FLAME™ is the most elegant, dense, and graceful of more than 50 clones of heavily-coned ("fruitful") redcedar evaluated by the society. This blue color comes mainly from the tens of thousands of glaucous female cones produced every two to three years. In the off years it is more gray-green. This remarkable, flame-shaped, tufted old tree has performed for many years in drought and heat.

Juniperus deppeana 'McFetters' gives richer glaucous-blue foliage and still retains the species' wondrous alligator bark, showing well after a decade or so. This is "wow stuff" for any conifer garden in warmer climates of USDA 7 to 10. This is reason enough for planting near a walkway for it only gets finer and firmer with time.

The green background foliage here is a from a shorter Cryptomeria. The pretty blue foliage is out of camera range.

Juniperus x ambigens (Fassett) Hatch - new combination
ha: spreading to 'matted' shrub with stems creeping to somewhat ascending.
la: apex subapiculate or intermediate between the two parents
hp: J. virginiana x J. horizontalis.
ns: this new combination is the most logical name for this hybrid. In
ns: 1945 it was common for taxonomists to assign an interspecific hybrid
ns: to one parent or another rather than create a new hybrid species.

Juniperus x ambigens 'Reptans' (Juniperus virginiana 'Reptans')

Juniperus 'Aquarius'
ha: low spreading mound to globose
ht: 3 ft.
wd: 4-5 ft.
fc: blue to blue green
rai: replaces compact 'Pfitzerana' type clones and 'Hetzii'
or: sport of 'Hetzii' (known as 'glauca hetzii')
so: Lake County Nursery

'Blue and Gold' - click on image for larger version

Juniperus 'Blue and Gold'
ha: erect-arching, very vigorous for a variegated conifer. Sprays are more open and loose than 'Hetzii'
lc: glaucous blue mottled yellow in the foliage mass. Shoots are about 20-30% yellow.
sex: female
frq: female strobili (cones, berries) numerous much like 'Hetzii'
or: thought to be a sport of 'Hetzii' but this needs DNA or chemotaxonomic study. It is unlikely to have origin in
or: in the J. x media Pfitzeriana Group as those plants are male.

Juniperus deppeana 'Mount Santos' ('Mt. Santos')
ha: irregularly conical, generally more compact than some variants
lc: silver-blue
ns: the word "Mount" should be spelled out and not abbreviated in cultivar names.

Juniperus deppeana 'Ohmy Blue'

Juniperus 'Green Mound' (Juniperus squamata 'Prostrata')
ns: this name applies to at least one major clone of J. squamata 'Prostrata'
ns: and is preferrable since the clone is not a J. squamata of any kind
rai: preferable to J. procumbens 'Nana' for greener effect
so: several wholesale nurseries including Hines Nursery

Why is it better?

  1. WEEKLY UPDATES from hundreds of experts around the world. It never goes out of date. The NOD is a dynamic, consistantly improved reference. This is what the internet is all about.

  2. MORE CULTIVARS THAN MOST REFERENCES. The NOD has the most cultivars for over 65 genera. As of December 2002 we had 84 Abutilon, 127 Achillea, 153 Agapanthus, 93 Aglaonema, 66 Ajuga, 256 Aster, 166 Astilbe, 125 Buddleia, 236 Campanula, 26 Campsis, 146 Canna, 69 Carex, 25 Clethra, 44 x Cupressocyparis, 75 Dieffenbachia, 36 Echinacea, 43 Erythronium, 95 Fagus, 16 Fothergilla, 64 Ginkgo, 73 Hamamelis, 23 Illicium, 90 Lantana, 57 Liquidambar, 63 Lobelia, 52 Mahonia, 69 Miscanthus, 92 Monarda, 43 Nandina, 102 Pieris, 23 Pennisetum, 98 Rosmarinus, 278 Salvia, 147 Sedum, 37 Sisyrinchium, 193 Thymus, 61 Tradescantia, 104 Veronica, and 53 Vinca cultivars. Click here for more cultivar counts.

    Check your favorite book - you'll probably find a half or fewer in each genus.

  3. CURRENT, ACCURATE NOMENCLATURE approved by horticultural taxonomists and explained in plain English.

  4. FIRST CULTIVAR ANNOUNCEMENTS. Many breeders and originators send their cultivar data to us first - weeks or months before you see it in magazines or nursery catalogs.

  5. LATEST LITERATURE from all over the world. We spend hundreds of hours a year abstracting and distilling articles on new and rare plants, their breeding, genetics, taxonomy, and history. We also provide precise literature citations for use in your own study and research. You'd have to spend over $10,000 a year to obtain all the journals, books, checklists, CD-ROM, abstracts, newsletters, theses, and dissertations that we examine and add every year.

  6. CLICKABLE ONLINE SOURCES. Knowing about new and rare plants is great. But we also help you find them for your garden. The NOD has thousands of clickable links to online nurseries offering a specific cultivar or rare species. And source links are added 52 weeks a year. And unlike most "plant finders" our links are TRULY INTERNATIONAL - not just the usual American or British focus.

  7. HIGH QUALITY DIGITAL PHOTOS. Our large 3.4 to 6.0 megapixel digital images bring new and rare plants to life in amazing detail, filling the screen. You find hundreds of fascinating photos on all groups of plants - perennials, woodies, and tropical.

  8. MORE DETAIL. We have cultivar specific information, origins and history of cultivars, identification tips, landscaping ideas, and trademark or patent data. You'll be amazed at how much detail the other references leave out!
