Re: heat zones, delphinium, etc.

Hi Gene,

Now there's a thought, although it could well be fraught with the 
same sort of difficulties as breeding stable, long lived reds which 
hasn't happened yet despite about 50 years trying. All the more 
reason to give it a go I suppose. I'll do some digging but won't hold 
my breath. This is something that would be in the background while 
my hair turns greyer and falls out I think.

cheers
