I am not a professional nor an expert in these plant groups taxonomy. Any help with ID and spelling are always welcome. Photos are for reference only. To up-date my list I've been using many books, journals, catalogs and other web-sites. It's been helpful, but I have more work to do. I only ship to the main 48 States. I do ship in the winter months. I can add 72+ hour heat packs for $4.00 each. No international shipping. Please read the front page for ordering information.

Gymnocalycium known for its heavy, backward-bent
spines and grey-green body, originating from

Gymnocalycium damsii monstrose grest sm -
This cactus exhibits both "monstrose" (random, lumpy, irregular growth points)
and "crested" (fan-shaped or serpentine growth along an elongated line)
mutations. This results in a one-of-a-kind, sculptural appearance for each
specimen, making it highly prized by collectors.
Coloration of the stem is typically green but can develop striking
reddish or brownish hues when exposed to sufficient sunlight or under stress
conditions.
Spines are generally short (up to 12 mm), whitish with darker tips, and often
sparse or absent in some parts due to the monstrous form.
The parent species G.
damsii produces funnel-shaped flowers, typically white to
light pinkish or greenish, and is a very free-flowering cactus. Crested forms
may have difficulty flowering or produce unusual crested flowers. These
are cutting from one of our old mother. The photo with orange stem is one of our
mother plants. Growing in 2.75" pots. 20 in stock @ $15.00 each.

a tough time trying to force themselves through the fierce spines, and is quite
