A. candidissimum are probably the pinks you are talking about. They also have white and yellow variants. The aroid hardiness list on the IAS site lists them as hardy to zone 4, that's probably someone just showing off. Many Asian Arisaema can take quite a bit of cold during dormancy if kept very dry and in very sharp drainage. Plant Delights and Heronswood both have Asian jacks, there are better less expensive places that you can find them if you do some searching.

Thanks KWoods. I'll try to keep looking for those places. If anyone can suggest other sites to check out, I'd appreciate it. I see that Wayside Gardens also has them for a couple dollars less. Has anyone tried them?Thank you

I bought A. trifolium from Wayside but they didn't come up this year. I received them in bulb form, not as a plant, and they were very small. They sprouted last year, but not this year so far. Sometimes, though, I have planted bulbs before that produce only root growth for a year or two and then come back, so I will patiently wait whatever the outcome will be. I ordered A. nepenthoides from Heronswood this year, as a plant. Good root system, but looks like it is dying back. However, I think this may be the habit of Ariseamas when the weather begins to get hotter.

Good luck.

Hi,

The one that is a bona-fide hardy Arisaema for your neck of the woods is amurense...they come from Russia and can take zone 3.....others are tough in zone 5.....you can also likely grow tortuosum and consanguineum....this has many wonderful variegated forms and is all in all highly variable.....of course Ar. dracontium is a sure bet for your neck of the woods as well....our other native jack. Best of luck :o) Dan
