'Cassie' is a little charmer of a rose, blooming in clusters of tiny (1 inch across) flowers, each with a center of cheery, bright yellow stamens. And bloom is nonstop, from mid-June until frost. Cassie is a rose that "plays well with others." At 3x3 feet, she won't crowd out her neighbors, but she will keep the garden show going when they're not in bloom. She has good disease resistance, so even with some shade and less than perfect air circulation, she'll do better at keeping healthy than many other roses.
