Arisaemas

21 years ago

I've got a number of arisaema seedlings which I have been carefully cossetting by keeping them under glass in winter etc. But I have been told they are hardy - can someone reassure me that this is true? I have mixed species, and also a sauromatum venustum (?) which I think might be related. I'm just thinking how good a nice, vigorous clump of these might look in the garden.

As the arisaemas are mixed, their hardiness could be variable and it would be better to err on the side of caution until they have grown and multiplied enough to afford taking risks.

The Sauromatum (New name is Typhonium venosum), does survive outdoors in many parts of the country but excessive cold or wet conditions can kill them off.

As with most other arum type plants, better results are obtained by starting them into growth early. This gives a much longer growing period to fatten the tuber which will then produce a large number of offsets.

Personally, I think they look much nicer in a large pot but must be given plenty of food and drink.

They seem to vary as to when they come into growth. Many have only just started this week - I thought I'd lost them - but some have been up for ages. Would this be an indication of the exact species? The sauromatum does not break until mid-July, I had to label the pot specially so I didn't just chuck it away in disgust.
How could I start them into growth earlier? More early warmth/moisture?

Have Arisaema sikokianum seed

Hi I think you gave me seeds years ago. They have bloomed for the first time this year and they were gorgeous.. I only took 12 seeds and I have 8 plants growing still... Only 3 bloomed this year. After about three weeks of blooming, suddenly the white bulbous flower and spathe turned into mush and is gone? Is that normal? Should I be looking for seed like a typical Arisaema tryphyllum? Boy, I hope they are okay they were gorgeous... Thank you again for your generosity. I will pay it forward..

Depends what you mean by the same exact plant. If it was grown from cuttings, for instance, they would be genetically the same. Your information says it is a subspecies, so it is something I would expect to be reproduced by seed. Am I wrong and it was tissue culture or cuttings? If something is reproduced by seed, it has different genes in the same way that you and your brother, if you have one, are from the same parents but not identical unless you are identical twins from the same exact egg and sperm. So in the same way that my sisters have different faces and hair color and only one needs glasses, your three plants will have slight variations genetically. I have read that even tissue culture can have some genetic drift if not done with extreme care, though I am not at all confident in this being factual.

Live in Ohio zone harsh 6a, was wondering about exotic Arisaema I could grow other than the common North American Jack in the Pulpit. Have grown Sauromatum Venosum, and Dracunculus vulgaris, going to see if A. konjac survives the first winter. Arisaema costatum? Arisaema speciosum (var. Magnificum)? Arisaema griffithii?
