  Re: Winter-active aroids

Al, most of the Mediterranean Aroids are wintergreen. Examples include
Arisarum vulgare, Arum palestinum, A. dioscoridis, A. creticum. I'm not
sure about the Biarums, not having grown them myself. Since winters in
Mediterranean regions are mild and rainy, while summers are really too dry
for the moisture-loving Aroids, the reversed growing season makes sense.
It's facinating to me how a few members of this largely tropical family
have spread into colder and drier climates with just a few simple
adaptations.

The Mediterranean Aroids are a particularly interesting group. The Biarums,
for example, are among the most highly evolved of the Aroids, their
inflorescenses having simplified down to just a few florets.

These plants tolerate mild frosts but are not particularly hardy; most of
them are probably risky in climates colder than USDA z8. A. italicum ranges
into northwestern Europe, but even it goes limp during dry freezing
weather.
