  Re: [Aroid-l] Dracunculus
From: Steve Marak <samarak at gizmoworks.com> on 2008.09.23 at 06:02:13(18571)
I've grown Dracunculus vulgaris outdoors here in NW Arkansas, US, for more
than 20 years and it's been surviving on its own in this area for at least
70 years. Doesn't spread on it's own, but established plants seem to be
very tough and survive lots of abuse.

During the time I've grown it, we've had a few -28 C overnight lows and
many +38 C summer days. I don't give it any extra water in summer or mulch
or other protection in winter, but I get inflorescences and seeds every
year. Usually it flowers around the first of June here.

It always comes up earlier here than it should, usually in late February,
and so has to survive a number of hard frosts. My unscientific observation
is that any temperature down to about -6 C will not permanently harm the
foliage, as long as it warms up during the day, but lower temperatures
(such as the disastrous Easter freeze of 2007, which went to -9 C on two
consecutive April nights after weeks of warm weather) will cause serious,
though not fatal, damage.
