Nursery contributed plant descriptions

Somewhat similar to the Arum listed below, but produces a dramatic black mottled spathe in the Spring. Sort of a scary looking flower with a rather unpleasant scent. But well worth growing. I haven't had a chance to grow it outside yet, I'm assuming that its only slightly less hardy than A. italicum.
Dioscoridis is probably my favorite arum, flower color is variable usually greenish or purplish with darker purple blotches and can be spectacular, see the photo in the AGS encyclopedia and be careful not to drool on it if you were too cheap to buy it and borrowed a friends copy.
