TBMA

Also written as TBM-A

If you're a fan of the classic long-form TBMA look, this is a nice one. It's got that unmistakable growth habit that collectors know for its long, smooth, goofy-looking shape.

Tell me when it’s cut

When a cutting off TBMA is listed, I’ll email you to say so (if you are not signed in, after you have opened the link I send first). I only have one of most things, so it is first come — nothing is held.

Email me when this is available. I understand this notice is about the plant I asked about, that I can opt out from any message, and that my address is not shared with anyone.

What it looks like

Skin
Reportedly smooth and spineless down most of the column.
Spines
Reportedly usually none, with an occasional ordinary spine and, rarely, a yellow one.
Growth habit
Reportedly tall and comparatively straight, and it does not stack its pups the way the short form does. Long, smooth and goofy-looking. In this yard it shows the classic long-form look, and once rooted it develops the classic knobby monstrose growth.
