ns: a silly and humerous confusion of the this German cultivar. It has appeared most recent in Beeches Nursery
ns: 2001 online catalog and hence made the RHS PLANT FINDER. "I'll be black....' or something like that.

lc: white margined

lc: dark reddish-purple but never blackish-purple as in 'Zwartkop'

lc: presumably brown(?)
so: cactuscenter.com

ha: very large rosettes
lc: reddish-black
so: Bob Smoleys

ha: stems fasciated and crested
lc: green as the species.
ns: the purple-leaved, crested mutation is referrable to 'Purple Crest'

ha: congested or clustered rosettes.
lc: light olive green
so: cactuscenter.com

lc: widely margined light yellow to about 30% of surface on most blades. Some rosettes on some plants may
lc: be light yellow with a green, the yellow being a full 60-70% of the surface. The 30% type rosettes are more
lc: common in our experience. There are some pink tints with age but it is not usually tricolored.

lc: green with some reddish-purple tints at the apices

ha: stems distinctly crested and fasciated
lc: dark reddish-purple as 'Atropurpureum'
ns: the cultivar name 'Atropurpureum Crest' is not valid and is not known before 1959. Hence this new name is
ns: proposed for this very distinct variant.
so: Bob Smoleys

ns: listed with the RHS HORTICULTURAL DATABASE as a variety but it is usually considered a species by
ns: experts in the genus.

so: cactuscenter.com (online catalog 2001)

lc: broadly margined in cream.

lc: dark and glossy blackish-purple to purplish-black, much darker than older 'Atropurpureum'. It is so darkly pigmented that
lc: bases of the leaves (center of rosette) is often redder and reddish-green at the extreme base where the blades
lc: attach. The blades are usually very glossy as if polished or lacquered. In shade is has more green sections and is more red overall.
ls: spoon-shaped, in some cases narrower than 'Atropurpureum'
ns: there are many spellings of the name. We follow the RHS in the choice of names. The name means "Black Head"
ns: so this is one cultivar name that best goes without translation! The name 'Schwarzkopf' does seem to have
ns: been in use in the trade prior to 1993 when the RHS awarded it. More research needed...
aw: RHS AGM 1993.

so: Bob Smoleys (2001 online catalog without description)

ha: crested and fasciated.
lc: bronzy green.

lc: lime green, center striped yellow and green. Not a normal "medio-picta" due to the numerous green stripes in the yellow central zone. A very pretty and complex look,
lc: especially with pink tints and pink margins in new growth (if light is bright)
so: Daniel's Cactus (online catalog 2006)

lc: margined yellow, chimera with 40-75% of surface - much like a more highly variegated 'Variegatum'. In some leaves there is only a thin green central stripe, the remainder all yellow.
so: Daniel's Cactus (online catalog 2006)

ha: fasciated or crested stem.
lc: cream, pink, or white margined on greyish-green as 'Sunburst'.
so: Bob Smoleys

lc: white margined becoming margined bronze-red
fc: white
so: San Marcos Growers (online catalog 2001)

ha: crested, fasciated variant on 'Variegatum'.
lc: as 'Variegatum'
ll: 0.4-1.1 in. long - shorter than 'Variegatum' which is usually 1.0-2.5 in. long
id, ns: apparently not the same as 'Sunburst Crest' since the variegation in this clone is not so wide or large as 'Sunburst' plants.
or: unknown but found by your editor (L. Hatch) in a pot at a Home Depot from a plant labeled A. decorum 'Variegatum'. Two of sections had
or: heads in normal rosettes as 'Variegatum' but half the pot had a large fasciated stem. This could be 'Sunburst Crest' though everything
or: I know called 'Sunburst' has much more than 15-30% chimera as this close does. This one is clearly tricolored with lots of pink tints on
or: the margins. I've seen this same offering at other nurseries and not one of them had fasciated sections so I trust this is a somewhat special find.

lc: margined cream to light yellow,chimera 15-30% of surface, new growth tinged pink (especially on the margins). Only a tricolor in strong light.

ha: very large rosette that is close to dinner plate size
ns: the name 'Dinner Plate' is a common name for A. tabuliforme and less frequently A. pseudotabuliforme so
ns: as a cultivar this name is not useable. If it proves to be distinct, that is a larger rosetted form, another name
ns: should be issued. Most recently the name appeared when Sandstone Plants of England won a Silver Medal
ns: at Harrogate in 1999.

lc: margined yellowish-white, often widest near the apex. Some leaves half chimera.

lc: mottled and striped white
li: Yokoi, M. and Y. Hirose. 1978. Variegated plant. Seibundo Shinkosha.

lc: green becoming dark red, the rosette usually centered green with much darker, contrasting old leaves having rich dark pigments. Bicolor effect overall.
so: Daniel's Cactus (online catalog 2006)

lc: thin cream to light yellow margins become margined pink with age. Not as bold as other variegates.

ht: very large, to 12 ft. with age
lc: green
fc: yellow

lc: irregular white margins, often wider on one side of the blade than another.

ht: 2-3 feet with age

lc: green

ha: slow-growing
lc: light green
or: said to be a hybrid.

lc: new growth in the center of a rosette distinctly light yellow. It later becomes green with yellow flushed margins
lc: though never sharply marginate. Older leaves are green with red margins, adding a tricolor effect.
