Re: [aroid-l] Question--Colocasia "Black magic"

From: Tony Avent <tony at plantdelights.com> on 2004.04.05 at 22:27:10(11364) Jason: Regarding your Colocasia 'Black Magic' question, I can share a bit of background. This clone clumps in most climates, but when grown as an aquatic, it does produce runners. In very wet season, we have seen the occasional runner. In tissue culture, C. 'Black Magic' mutated to a form that runs in all climates. It was given the name C. 'Black Runner'. This form also has leaves that emerge darker and have more ruffling around the edges. I hope this helps. +More At 01:15 AM 4/2/2004 -0500, you wrote: >"Dean Ouer" wrote: > >>Can any of you aroid experts answer the following question about the "Black Magic" colocasia? >>I grow it in So California and also in Hawaii. The leafs look identical to me in both locations so I always assumed they are the same species. However, when grown in California it "suckers" only right next to the base of the mother plant. The suckers are so close it is even hard to split off the "pups." In Hawaii it sends out long runners (3-5 feet long) with a plantlet on the end like I have seen other Colocasias do. But the "Black Magic" I grow in California has never sent out a runner. And the one I grow in Hawaii only seldom suckers close by. >>Are there two different species of "Black Magic" or is this difference in growth due only to climate? > >The differences you describe, sound like subspecies/varietal differences! Colocasia esculenta has 3 subspecies/varieties: C. e. esculenta, the nominate form; C. e. antiquorum; and C. e. aquatilis. Could it be that the 'Black Magic' leaf has appeared in two different subspecies/varieties? > >Jason Hernandez >Naturalist-at-Large > Tony Avent Plant Delights Nursery @ Juniper Level Botanic Garden 9241 Sauls Road Raleigh, NC 27603 USA Minimum Winter Temps 0-5 F Maximum Summer Temps 95-105F USDA Hardiness Zone 7b email tony@plantdelights.com website http://www.plantdel.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
