[Aroid-l] arum question

From: crogers at ecoanalysts.com (D. Christopher Rogers) on 2007.09.14 at 15:55:23(16286) Hello, Tony! Maybe you are correct about the envy. But we must all remember that no matter which aroids we enjoy, we are all "brothers in arums". Yes, I have had that happen. It does not happen every year, but it does happen. I have a bed of A. italicum on the north side of my home, right under the condensation drip of my air conditioner. Additional shade is provided by a 1.5 meter Tasmanian tree fern and lots of sword fern. Add to that a top dressing of babies tears, and this one bed stays fairy cool and moist. As a result, a small fraction of plants do not go dormant during the summer about every three years or so. The plants that did not go dormant in the summer always do in the autumn, and start poking up again mid winter. I tried to recreate these conditions as an experiment and the tubers rotted. As a side issue, I have had an A. palestinum ecotype from Mt. Carmel break dormancy in July and August rather than December/January, but again not every year. Also, I think that CJ Addington has had A. pictum bloom in the spring rather than in the fall. In that same vein, I have one Pinellia pedatisecta starting to come up. It and all its buddies just went dormant a month and a half ago. Grins, Christopher +More D. Christopher Rogers Invertebrate Ecologist/Taxonomist ((,///////////=====< EcoAnalysts, Inc.

It's almost time for them to start re-emerging and this one thinks it's still spring. -- Tony Avent Plant Delights Nursery @ Juniper Level Botanic Garden 9241 Sauls Road Raleigh, North Carolina 27603 USA Minimum Winter Temps 0-5 F Maximum Summer Temps 95-105F USDA Hardiness Zone 7b email tony at plantdelights.com website http://www.plantdelights.com phone 919 772-4794 fax 919 772-4752 "I consider every plant hardy until I have killed it myself...at least three times" - Avent _______________________________________________ Aroid-L mailing list Aroid-L at www.gizmoworks.com http://www.gizmoworks.com/mailman/listinfo/aroid-l
