O basilaris is one of the easiest opuntioids to germinate. Just heat and water, sunshine and no standing air. But in our climate in Scandinavia humidity is the big challenge and they cannot grow outside at all. Inside the unheated greenhouse in terra cotta pots they do fine. Grown in well drained mineral soil and only water in sunshine betwin late april and end september.

Here are some of those I have had my hands in:

Great photos Martin!! You always have good ones on your websight!

Here are the last two varieties of O. basilaris I grow.  O basilaris var. heilii. (syn.- var. longiareolata) and  var. brachyclada.

Var. heilii is a fairly new variety and there appears to be some contraversy as to whether is should have varietal standing or stand as separate species in it's own right.
The variety was described in 1983, and is endemic to southern Utah. It is found in only three counties Emery, Garfield and Wayne Cos.
It is listed as a synonym under O. basilaris var. longiareolata in the Flora of North America.
In my opinion it should be recognized at the species level.  Its growth habit is different than O. basilaris. It only grows in a very isolated, remote area at higher elevations, and withstanding  and survives in very cold weather. Its pads epidermal surface appears to be smoother and doesn't have the velvety texture found in " O. basilaris. The shape, color, and thickness of the pads are different. The the protruding shape of the areoles is different, and the areoles are spread out and fewer in number.

The next variety is Opuntia basilaris var. brachyclada. Var. brachyclada has low stature, seldom getting above 40cm (16 in) in height. Stem segments (pads) are typically 5-13 cm (2-5 in) long and 2-5 cm (0.75- 2 in) wide, sometimes slightly flat but generally cylindric to club-shaped. This species is  spineless  but has abundant glochids. Flowers are a bright pink to magenta.

Different forum but same result, you continue to make me jealous with all your nice basilaris plants.

This second form is both dwarfed and the pads come out heart shaped. Again the pads are about 1/3 the size of the standard variety basilaris. In all other respects it is the same as variety basilaris.

Hmmm, I really like the look of this one. I may just have to give it a try!

That's one I've never heard of before. Sounds like a little one. What can you tell me about it.

I don't know much about it.  I found it on ebay this winter and bought 2 small pads.  I have no idea how cold hardy they are, but thought it would be fun to try it out. 
You are welcome to a pad if you want to try it?  I don't need the other pad, they look like the will produce well. :)
