Allium zebdanense Allium neopolitanum

Jim,
I looked up the monograph on Alliums of Dilys Davis. He states that A
neopolitanum is the valid name and that A. cowanii is an invalid synonym.
The form known here known as A cowanii should probably be considered as
a form or selection of A. neopolitaum. It is widely used here in the cut
flower industry, because it has long rigid upright stem with a good size
umbel of larger flowers, while A neopalitanum has often bend or even
rampant flower stems.

I've read that much, maybe all, of the material commonly sold as Allium
neapolitanum is in fact A. subhirsutum or other species.
Here in zone 7, I've had trouble keeping stock received under the names A.
cowanii and A. neapolitanum.
