Hello,
Arisaema candidissimum has been growing like a weed for me. So I have a lot of big bulbs to give away (I'll send them after the frost is gone (the end of February, the beginning of March). Anyone who's interested let me know.

Wim,
in my garden Arisaema candidissimum is not frost hardy. What lowest temperatures have you usually in your garden if you grow it outdoors?
-
Zdenek - A. candidissimum is not reliably winter hardy here either.
We usually go close to -17c once or twice a winter, sometimes without snow cover.
Can you tell us which Arisaema species are hardy for you?

Zdenek,
A. candidissimum is winter hardy here but we usually only get temperatures to - 5°C without snow cover. Now it's a very hard winter here with temperatures to - 10° C. But I grow some in two large troughs (http://www.srgc.org.uk/smf/index.php?topic=1851.135 (reply 145)) also which go inside during winter. Now I want to empty one trough so I have room for other plants and that's why I have approx 25 flowering sized bulbs (and a lot of small bulblets) to give.

Hi:
Low temperatures would not be a problem as these and many other bulbs/corms/tubers can be easily lifted for the winter and stored in dry wood shavings in a frost free place to be replanted in spring.

Arisaema candidissimum grows outside here to -9'C at least (it is dormant in winter after all). We don't get any snow cover. It is under the very edge of a large deciduous magnolia, so I doubt it gets much in the way of extra soil warmth. I also have pots with it in that have survived the same temperatures without a hassle, flowering very well as always.

Hi Wim,
I'm very interested and have replied off-line.
Cheers,
Darren.

I have some bad news. Last year I had an infection of Dasheen Mosaic Virus in one clump of my A. candidissimum with visible infection of the leaves. They had been growing like that (with those symptoms) for years but it was only that year that someone told me it might be a virus and since there was no slowing down of growth or flowering I had never paid it any attention.
So, I had the leaves tested and they tested positive in only one of my troughs. The other ones (without those symptoms) seemed to be clean. Now I had the bulbs tested (to be save) and one of three I sent was found positive too. So I have no way to know which ones are infected and which are not. I'll destroy my entire collection of A.candidissimums.
So, I'm sorry but I refuse to send out any bulbs that might be infected.
Kind regards
Wim

Hallelujah!
If only one among a thousand growers would be this serious and responsible I can not even imagine what the horticultural world could be!

What a disappointment for you, Wim, but, as Alberto says, what a very sensible and responsible course of action you take in the wake of finding this problem.
I will close this thread now.
