I received our Marie Daly as a transplant last spring, even though we had a much warmer than normal winter in 2011, Marie Daly lost only a few leaves, and even in the warmest part of the winter-when it was in the 80F range, we had a bloom or two.

The rose is very healthy even in hot humid conditions, or cool humid conditions, it did show a slight bit of blackspot, but I just I just hosed the plant off, and then drier sunnier weather conditons took care of the rest.

It does have a few prickles underneath some of the leaves, but I would say it is thornless. In cooler weather the blooms look more like miniature hybrid tea blooms, wonderful fragrance, it has a nice tidy habit, and looks good by the kitchen door.

Salvia, Henry Duelberg

"One of this year's promotions, the Duelberg sage (Salvia 'Henry Duelberg') happens to be a plant that I found and introduced to the Texas nursery trade. I'm a decent plant breeder but my forte seems to be stumbling across improved plants in unlikely places. For instance, the Gold Star esperanza came from a yard in an impoverished neighborhood in San Antonio. The Marie Daly rose was a sport in my mom's backyard in the Pineywoods of East Texas. And the VIP petunia came from a flower bed in front of a pay toilet in Stuttgart, Germany!"
