Family: Crassulaceae (Stonecrops)
Scientific name: Aeonium
arboreum var artopurpureum 'forma cristata
Origin:
Garden origin (Nursery
produced cultivar) For a long time this choicest
cultivar has been considered a
sport of the Aeonium arboretum.
It now seems that it comes from the Canary
Islands, thus
it then cannot be a cultivar of A. arboreum,
since A. arboreum doesn't come from there.
The latest theory is that it is a cultivar from A. manriqueorum.
Common Names include: Crested Black rose,
Crested Black Beauty,
Crested Black Tree Aeonium
Synonyms:
- Aeonium manriqueorum forma cristata

With almost black leaves on a light grey trunk is very
showy. Looks wonderful next to any blue turquoise succulent.
Cultivation: It requires gritty
well drained potting mix. Water deeply but infrequently. Plants are
allowed to thoroughly dry in-between waterings. During the winter
months restrict water to about once a month, or just enough to keep the
foliage from shrivelling. Position in full to part sun in a sheltered
spot, but the bright light enhances the rich hues of the darker Aeoniums,
and the subtle blushes of the other colours, but prefers light shade to
shade in summer. The plants tend to go dormant in the summer and look a
little tired sometimes, but they perk up again in the fall. Summer is
the natural dormant season for this species in its native land. Needs
protection from severe winter frosts (Hardy to -2°C or a little less for
short periods), over winter under glass in all but the mildest of
gardens.
Propagation: It is easily propagated by cuttings in the spring.
When the stem becomes too tall, just cut the top
rosette with a piece of stem and plant it. It will soon take root, while
the plant left with just the stem will soon grow new buds that can be in
turn used for propagation. Time to take cuttings: April to July
