Winter-active aroids

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 transgressions. +More Clear skies, Al +-------------------------------------------------------+ | Alwyn Wootten (http://www.cv.nrao.edu/~awootten/) | | Astronomer, National Radio Astronomy Observatory | | 520 Edgemont Road, Charlottesville, VA 22903-2475, USA| | (804)-296-0329 voice Let's build The Millimeter Array| | (804)-296-0278 FAX {> {> {> {> | +------------------------------^-----^-----^-----^------+

From: "Robert Wagner" <robwagner at robwagner.seanet.com> on 1997.01.08 at 00:30:21(64) 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.

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? -tony avent +More plant delights nursery raleigh, NC Tony Avent Plant Delights Nursery 9241 Sauls Road Raleigh, NC 27603 USA USDA zone 7, 0F-100F

I believe that both Craig Stubbs (who lurks on this list, right, Craig?) and Andrew Osyany grow the same clone of this outdoors near Toronto - a far cry from zone 7. If Craig doesn't fill us in, I'll see what I can find out. Ellen Hornig

I am cradled between Zone 6&5 (East of Toronto) and have had great luck with Arum Palestinum.Although it has yet to flower, I have moved it within the garden several times and now have 10 corms from 4 seeds after 3 years.It loves to come up for a second growth cycle in December here so I often bring half of them inside and grow them off,put them in the fridge for two months in say March and then back outside with their buddies to enjoy a natural summers growth. Breifly I find them stone hardy . I will be ex cummunicato for about a week as I am moving but look forward to meeting with you at the WSW in two weeks.
