Everyone wants linearis, and minor "Okee Giant" :-). However
there seems to be some problems with getting them. For one,
they're hard to find. For two, one is hard to grow.
I've heard of a few growers who've had linearis over the years,
but none of them have it currently. The complaint was that the
plant was really hard to grow, particularly in CA. The plant
will supposedly grow in acid conditions instead of the alkaline
conditions it favors in nature, but it has a very long dormancy
period and prefers shorter days. People lose it to rot in
dormancy.
The problem with "Okee Giant" is that there may be some false
clones floating around. Peter D'Amato has one he got from Bruce
Bednar, or Orgel's, (I forget), and it's not even as big as a
normal minor. He has another clone however which has at least
2' pitchers, but it's not IDd as a giant form. Psittacina Giant
may be easier to find via a commercial grower. There are at
least two giant forms of S. minor: "Okee Giant", and just
"Giant form".
I think the ping you meant is microceras (?). Isn't this a form
of vulgaris?
