Description: This is the nice crested form of Copipoa
humilis with olive-green,
or somewhat grey-green, or rarely red-brown stems that forms nice
brain-shaped mounds. The apical line meristem is somewhat depressed
often with white woolly felt. There are several clones and the
dimension of the mound varies from 10 cm to 30 cm in diameter (but often
more in cultivation, especially if grafted) moreover the transversal
thickness of the crests vary from 2 to 8 cm.
Given insufficient light and too much water, they grow into great
masses of fat, olive-green crests. Given a very bright
position, the stems are dark tannish-green, brownish to almost black at times, with red and
purple. There are indeed marked
differences in sizes, epidermis colour and spines length in plants from different
clones, and also the growing condition (especially sun exposure,
water availability and grafting) determine conspicuous differences in habit of
cultivate specimens.
Root: Massive, thickened rootstock going well down into the ground,
with a long narrow neck.
Flowers: Yellow,
campanulate, scented, about 30 mm long, growing from the
centre of the white wool at the
apex.
