Hardy Aroids

From: "James W. Waddick" <jim-jim at swbell.net> on 1997.10.24 at 03:48:14(1484) Dear friends; This string has turned from Dracunculus to Hardy aroids and I am surprised that no one has mentioned Calla palustris. This gets to considerable size, has impressive flowers and fruits and should be hardy fairly far north - Zone 4, 3?. Then there's Orontium, Peltandra, and Typhonium, Zantedeschia..although the latter two may only have 1 or two species hardy through Zone 6. I'll bet theres other beside the ones we've already talked about Dracunculus, Arum (various species - I have italicum,maculatum, orientale and nigrum in Zone 5/6 - others ? I lost dioscorides ) Symplocarpus, Lysichiton, Arisarum etc. (not to mention Arisaema - that's another robin) +More How far north does anyone grow Helicodiceros ? These are just a start, let's get complete here: Best Jim James W.

Jim, I've tried to get Calla palustris several times unsuccessfully - seeds from an exchange never germinated for me, and plant sources haven't worked out. Is anyone growing this? > Then there's Orontium, Peltandra, and Typhonium, > Zantedeschia..although the latter two may only have 1 or two species hardy > through Zone 6.

All of my Zantedeschias except the recently-acquired "Hercules" are outdoors and all but one of those (Z. pentlandii) have been for several years. Re Typhonium, there was a deafening silence a few weeks ago when I asked some questions so I will risk repeating them here: >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.

Orontium should be hardy, but I don't have it and don't recall anyone else talking about it. Why is it so unpopular? Steve +More -- Steve Marak -- samarak@arachne.uark.edu

From: Doug <dburdic at presys.com> on 1997.10.27 at 15:06:46(1499) Hi Jim and Everybody, Collecting hardiness feedback from the group on all these species is an excellent idea. I can add to this that I am growing one Arum italicum here on the central Oregon coast (Zones 8-9) which is no big trick I realize, but thought I'd mention it. +More > > How far north does anyone grow Helicodiceros ? In addition to the answer to this question, I would like to receive the answer to an even harder one: Where can one even purchase Helicodiceros?! It seems that it would be easier to locate the Lost Ark of the Covenant than a commercial source for this particular species.

Tom<< Dear Folks, A few years ago I collected Orontium near Sebring, Cen. Florida, and grew it very sucessfully here in W.P.B., Florida for many years. Tom photographed it when he passed through on his way to Fr. Guyana. It is a beautiful and easy plant to grow. Mine responded to the method I outlined for Urospatha in Vol. 16 of Aroideana, and produced large numbers of big, viable seed that germinated while they floated in the water of the saucers! I believe that I finally gave it to some visitor who was passing through. I recomend it highly. Cheers, Julius ju-bo@msn.com >

From: "Dr. Victor G. Soukup" <soukupvg at UCBEH.SAN.UC.EDU> on 1997.10.28 at 17:44:00(1543) Calla palustris normally grows in wet bogs in mostly full sun. For a source I suggest that you look for plants in Michigan and when you spot some (there are usually a lot of them, or one plant with many, many leads), just reach in and pull up a front lead. Calla is not a rare plant and removing one or two will not destroy the populations. Be careful, hpwever, because massasauga rattlesnakes like the drier portions of these same habitats, and in trying to avoid the deeper, muckier pools you are apt to head for the higher drier ground. Good luck, Vic Soukup +More On Mon, 27 Oct 1997, Don Martinson wrote: > >James W.

From: Kristl Walek <garnorth at istar.ca> on 1997.10.29 at 06:03:16(1551) Steve: I run a seedhouse for hardy rare perennials called Gardens North in Ontario, Canada. I am growing Calla palustris quite successfully here (a cold Z4) and saw it often last summer on a seed collecting trip across Canada, both in the wild and in gardens in Zones 3 and colder (Northern Saskatchewan and Alberta.) Unfortunately it will be another few years before I have enough seed producing plants to offer it in my catalogue. If you manage to get hold of some more seed.....try the following: -the seed will do much better being sown in a "muck" (a muddy compost). I normally sow in waterproof containers (recycled plastic take-out is fine). Allow the water to be about 1" higher than the soil in the container. This is a good general method to use for many water loving species. -give an initial warm period (as warm as possible) of about 4 weeks. -Then provide about 6-8 (or longer) weeks cold. It doesn't matter if the muck freezes. So you could pop the lid of your take out container on and either stick it in your fridge, or put it outside mid winter... I have successfully germinated it on many occasions using the above method, although my seed was always fresh, so I do not know if this is an issue. Are you in Canada, by any chance??? I don't ship plants outside of the country at this point.... Kristl Walek +More Gardens North
