These prices seem appropriate for the Treasury. Two years ago, I planted
A. italicum (5 for $5 as I recall) among my Hosta, and have been delighted
each fall as they send up their foliage amidst the debris of the Hosta.
What others among the hardy aroids have a reverse season like A. italicum,
leafing over winter and blooming in the spring?

By the way, thanks Wilbert and others for the taxonomy discussions. We
have similar problems in astronomy of course--witness the lovely thermal
classification scheme, strictly alphabetical, for stellar spectra devised
in the last century. Alas, helium was unknown, so spectra with helium
lines got thrown any old place and the alphabet has now become OBAFGKMRNS
with lots of letters lost by the wayside. But the naming of planetary
features, asteroids and the likes falls strictly under the rule of the
Commission on Nomenclature of the International Astronomical Union. Although
whatever they say, is the law, any professional journal is full of

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

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

As for the comment on biarums, we are experimenting with many
biarums here is zone 7...some made it through last winter at 0 degrees F.
We have planted many more this season...don't have time to get a list
together right now. We are preparing to test Arum palestinum. I would love
to hear of experiences with this plant and the coldest temps that it has
endured in gardens...anyone in USDA zone 7 had Arum palestinum overwinter yet?

Biarum davisii grows well in winter here, nice and green.
