Re: [Aroid-l] Dracontium amazonense

From: "Daniel Devor" <plantguy at zoominternet.net> on 2009.10.05 at 11:36:55(20155) I can say that my various Dracontium (prancei, polyphyllum, 2 no-IDs from Brasil, 1 no-ID from Ecuador (too young) and one no-ID from who knows where) that I have had for between 3 and 5 years (with a couple of exceptions) have never flowered except the prancei once after a dormancy. They have all stayed virtually evergreen except for maybe a month here and there (3 dormant now) and so far no influorescence. The prancei has produced a nice petiole this summer in nearly full sun that is 1.3 m tall and the largest polyphyllum has a petiole approximately 0.8 m tall and still emerging (this is the second petiole on the tuber after a short dormancy). Mine obviously rarely flower, and this could be my growing conditions, but honestly, just like Amorphs, I think the petiole and leaf is the real reason to grow them :o) I really wish this genus was more widely grown so we could all try a few additional species!! I find the offsets very tough, but once they get a bit of size on them I find them to be quite enjoyable even in my zone 6, no GH conditions. If anyone ever has any tubers they can spare I'd love to hear about them :o) Dan HTML +More Gibsonia, PA ----- Original Message ----- From: ju-bo@msn.com To: aroid-l@gizmoworks.com Sent: Sunday, October 04, 2009 8:37 AM Subject: Re: [Aroid-l] Dracontium amazonense Dear Friends, My thoughts on this interesting question are that no, when the plant reaches some point in its growth cycle, even without dormancy, it will bloom. This is NOT a tested and proven fact, just my opinion! Wilbert, your thoughts??

Let the species name ''amazonense'' tip you off! There seldom is a dry period in the Amazon region where this species occurs naturally! There are a few other species of Dracontium (D. spruceanum comes to mind) which can be grown year-long with no dormant period. One can ''force'' dormancy by letting the pot dry out, but most growers would not recomend this. The late Lynn Hannon was one who had them grow all year, keeping them moist.

I have heard that drying them out will induce dormancy, but have never tried this? dst On Oct 1, 2009, at 2:03 AM, E.Vincent Morano wrote: I have a Dracontium amazonense that I wrote about before. Now it has grown a new leaf alongside the one it had all season. I thought these grew durring the year and then went dormant for the winter months. So first should it be growing a new leaf (a bigger one at that) and second when should/how should I let /make it go dormant?
