Some of the Bucks have done well for me and some haven't. I do think they tend to be healthy and hardy, but some are hardier than others. I lost my Quietness and Prairie Sunrise plants and Distant Drums is a weak grower for me but beautiful.
To me the most fragrant are Quietness, Prairie Breeze, and Folksinger has a nice tea/ tobacco fragrance. My strongest plants are Carefree Beauty, Folksinger, and Prairie Breeze. I like Quietness and Prairie Sunrise so much I am establishing new plants of those.
Carefree Beauty
I have two plants of this one...the one in more sun is practically blackspot free but the other gets some.
Folksinger, makes a dense and vigorous shrub with great repeat and hardiness. At times leaves are healthy, but sometimes they're not.
Folksinger on the left
Prairie Breeze...very early to bloom and late to quit. Healthy and hardy in my zone 7. Strongly fragrant and full of petals, large blooms.
Prairie Sunrise...blooms are BIG
Quietness...just a beauty
Griff's Red very healthy, and fragrant. Lost my plant to lack of water.
Distant Drums
Hawkeye Belle is a beauty and good grower
