>Steve, what do you mean with "both" species? If you mean S. venosum and
>S. brevipes, then you are right but if you mean S. venosum and S.
>guttatum, they are the same species to begin with.
Wilbert, yes, venosum and brevipes were the "both" I had in mind. Is
brevipes what used to be horsfieldii (sp?) or is that yet another alias
of our friend?
Re Typhonium giganteum, I now have plants from several sources (as is my
habit), some with me for several years now, but none have yet flowered. This
may well be due to location - the oldest, which have increased each year in
leaf size, are in a rather shady spot.
They seem quite hardy, from all sources, but as Jim says are so late to
emerge each summer that I'm just now able to restrain myself from digging
about in the dirt to see if they are still there.
While on hardy Typhoniums - Deni Bown, in the 3 paragraphs devoted to
Typhonium in "Aroids", mentions 2 other species as "hardy": T. diversifolium
and T. alpinum. "It (T. diversifolium) is found in the Himalayas between
2500 m and 4300 m and so, like Arisaema flavum, is a near-alpine. The
ability to grow at high altitudes is also seen in T. alpinum which is
recorded as reaching 4000 m in China."
Can anyone comment on how hardy these species truly are? 4000+ meters is
high enough that (anywhere much short of the equator) it implies some good
frosts.
