Greetings All, I'm looking for some planting tips for some corms of Arisaema I recently received from J.L. Hudson. The species are: A. propinquum, A.fagesii, and A. Flavum. In late spring I received a corm of A. taiwanense from Seneca Hill Perennials - I potted it up and watered it perhaps once every 10 days and it popped up within a few weeks and bloomed. Cool - I figured "how about another Arisaema?" So, earlier this summer I potted a corm of A. propiquum and treated it similar to A. taiwanense and it never did anything. I dug it up last week and the only remaining evidence of the corm was a dried, hollow husk. It looks like all of the flesh rotted. Should I have waited until I saw active growth before watering? I'm not very familiar with this genus or its horticultural requirements. Poking through past posts including topic of topic of the week gives lots of descriptive info on the species, but does not delve into too much detail regarding culture or special treatment, except to say that they're pretty easy. Any tips on the best way to plant and for corms to prevent rot before they come into active growth would be much appreciated. ~Byron in San Rafael, CA
