I don't know the answer to your question, but I'd like to know it -- my only suggestion is that you post your question on the Cutting Garden forum here, where a lot of market cut flower growers post. Good luck!!

Here is a link that might be useful: Cutting Garden link

I'm No expert but have a look at Pee Gee. That's what they grow in Tx for cut flowers, I would think it'd grow where you are.
