Dracunculus foliage

From: James Waddick jwaddick at kc.rr.com> on 2003.04.29 at 14:06:47(10138) Dear All; A few years ago it seems like the only Dracunculus I ever saw had all green foliage - without white chevron marks/stripes. Over the last few years I have been more successful growing this species and all my mature plants have these striking white chevrons. I recall hearing that only certain geographic forms were so marked. True? I noticed that seedlings and small offsets have clear unmarked leaves. Any comments on the incidence of this marked/unmarked forms of Dracunculus? +More Thanks.

However, while it is true that the vast majority of plants on Crete are so marked, the variegated form also occurs in western Turkey and also crops up on other Aegea islands.

It seems nobody talks about much of anything on here for ages, and then all of a sudden the floodgates open, and the conversation gets really interesting! This spurt of Dracunculus talk is right up my alley - I love these guys and grow a bunch of them. Last summer I used pollen from one of my heavily white-chevroned Dracunculus to pollinate the bloom of a completely non-variegated plant just as an experiment to see what would happen, such as what is dominant, how many babies are chevroned, etc. That pollination produced a huge berry cluster that I sprouted on my patio. I now have over a hundred cute little mixed-pattern baby Dracunculus, and at this stage (1-2 leaves) not one of them shows any white at all. So, either solid green is 100% dominant, or babies just don't show any white chevrons. I look forward to rearing them up to see the percentages of chevroned vs. plain green. If anyone would like some of these babies (I cannot grow 100+ plants of one thing on my patio!) I would be happy to share them, if you would just let me know if it turns out green or chevroned. I think these guys are so cool that everyone should grow them! Of course, I live in a Mediterranean climate, so perhaps I am biased. Love to hear about other folk's experiences with these neat plants. Cheers! CJ Addington +More cjaddington@earthlink.net

To CJ Addington and interested parties, Perhaps you should try the reverse cross using a "chevroned" pod parent. The "science" can get very complicated but if aroids share the three somatic layers (L1, L2, and L3) that hostas and many other plants have, then variegated inheritance might best be accomplished this way.

Hi Jim! It never occurred to me that the direction of the pollination might affect the rate at which the variegation is inherited. Of course, most of the time I am limited by what I have handy - I use whatever pollen is currently being dumped by a sexed-up bloom! : ) If the possibility arises (and it well may this month as my various plants bloom) I will have to try that cross in the other direction as you suggest. Also, I will try a direct chevroned-to-chevroned pollination to see if I can intensify the chevron effect. Thanks for the ideas! PS - To all the Helicodiceros fans out there (I had NO idea there were so many of you!), I think I now have enough people on my offset list for that species to cover all the potential babies that my clump will produce. However, I am just approaching my great, annual May and June rinse-and-sort-athon, and should have lots of extra corms, offsets, seedling corms and seeds of MANY different species of Arum, Biarum, Dracunculus, Pinellia and other neat aroids. My garden and patio are only so large! I would be happy to share and trade all the extras that I end up with. Once I have a feel for what I have available I will send out some notices, or you can just email me directly. I just love getting other people to grow some of the plants that I love so much! Have a great Mayday everyone! Cheers! Christopher "CJ" Addington +More cjaddington@earthlink.net

From: SongString at aol.com on 2003.05.02 at 04:39:21(10158) Anyone have the Amorphophallus Konjac? I bought a tuber a few years ago at garage sale in Southern Ohio and had no idea what it was, until a few days ago, when I did a search on the web and came across it. It is blooming for the first time. The flies are having a great time around it and it is starting to stink. A good sign huh. I have never seen anything grow so fast in my life. IT grew about 6 feet in a week! The tuber was 13 lbs. and had divided in two, so it is twins now. Plus I have some baby tubers also. How rare are the A. Konjac? I'm assuming that is what I have, since it looks just like all the photos I've seen on websites. I live in Northern Ohio. Nancy
