Wow.. this is one I haven't seen before, love it.

Ditto !
I haven't come across 'Heirloom' variety either, is this another name for an old variety or a new group ?

I'd venture old variety. Reese Greenhouse has a pretty old stock of seed they draw from year after year. They started them there. All my colors came from that seed variety. Just a six pack. They consistently have the little double bloom inside the outer. I'll run over and quiz them when I get the chance. :-)

I'd be very interested in what they say, Greenthumb, and whether they can be found here in the UK.
