I grow quite a few of Pat's and they do very well here on the edge of zone 6/7.
I need to grow more of her little ones but really like Little Lemon Twist. It is a perfect pinched crispate form on a 3.25" bloom! It is nocturnal and blooms begin to open by 7 PM - grows like a weed here!
Also LOVE Snow Crab - have just had it a couple of years and it will need dividing in the spring. It is registered as 4.5" so it qualifies as a large flower, but looks like a small flower and has many blooms open at once.
Would love to get a few more of hers too!
