From: mburack at mindspring.com> on 2002.04.15 at 20:51:13(8564) Ironically, I am starting to think than T. giganteum isnt only hardy in cold temps.. I am about ready to believe that it doesnt like hot temps period... I routinely kill mine at the beginning of our spring and summer here as temps get out of control. (For those "friends" of mine that itching to make a comment something like "you routinely kill all of your plants, not just the Typhoniums and not just in the spring and summer"... lets just let that slide this time around!!! (SMILE)).

In my Zone 5 garden in Kansas city, T. giganteum is THE LATEST aroid to emerge. Just when I have given up and realized it finally croaked last winter it pops up in July or August!! I never even see it is spring and early summer. By the time it finally emerges, we have had weeks of 100F plus. Of course you didn't mention where you live or climate info. It has very shallow tubers and these seems to go 'up and down' in the soil over the year. After blooming new small round tubers roll away from the parent plant and then seem to disappear until next July. If I don't catch a few tubers in fall, I can rarely find any to move them to a new location. I still haven't convinced myself if it does best in sun, shade or half way there. No clue Jim W.

By the time T. giganteum shows up, I've usually forgotten it's there. > I still haven't convinced myself if it does best in sun, > shade or half way there. > > No clue Jim W. Again, same here. I've tried all three. I've nearly talked myself into favoring half shade, but that might be because I don't want to move them again. I do get better flowering than in full shade. Despite years of inflorescences, I've yet to see a seed. Steve +More -- Steve Marak -- samarak@arachne.uark.edu
