Thank you. I should have known, I have a lot of the kind with many thorns and the stem gets hard like cable, I had never seen it so big around before, but it's still the same basic growth habit. And, thanks for introducing me to Green Deane. Excellent video and website. This post was edited by garden2garden on Sat, Apr 12, 14 at 23:28

I don't know, but it grows in San Luis Obispo, CA according to this site, so probably. It's hardy to 10 F, so it's not going to freeze there unless you have an unusually cold snap. Orchid Rock Rose

Thanks for your input. I'm surprised humidity is a factor because those hybrids are of Anise hyssop and A. rugosa (Korean) are both native to moist places. Perhaps it is the heat then.. I'll still test them out but I'll only start with one plant in that case. As for the Southwestern ones you may wish to try Agastache aurantica cultivars they are supposed to handle more summer water and they have a good, quick germination from seed or at least mine did (I use Swallowtailseeds). I grow 'Arizona Sun' (pictured) and 'Tango' Agastache aurantica just fine in pots (over a bed so they can root into the bed). I add vermiculite to the potting mix to make it a little more neutral+well drained around the crown. I also grow some 'Arizona Sun' in-ground in a west facing bed that is very well drained + has ample root competition from old palm trees. Some look quite rough after the wet season here but none have died thus far. They do require deadhanding for tidiness as the entire branch dies back after seeding otherwise. They are short so they are good for containers. The leaves are intensely minty in a good way and I use them for teas.

Do you spray antifungals, and how does Mary Rose do for you as the year progresses?
