USDA zone 6b through 9b (default). Can be used for beds and borders, container rose or garden. Remove spent blooms to encourage re-bloom. Spring Pruning: Remove old canes and dead or diseased wood and cut back canes that cross. In warmer climates, cut back the remaining canes by about one-third. In colder areas, you'll probably find you'll have to prune a little more than that.
George Engelmann was a German-born American botanist who settled in St. Louis and collected plants in nearby states, includingTexas (see comments). One of the plants he described is Rosa minutifolia. Dr. Engelmann's involvement was central to the founding of the Missouri Botanical Garden.
