‘Rosie Posie’ bears loads of hot pink flowers with magenta purple calyxes just at the top of the foliage for a neatly proportional look. Because the calyxes are so colorful, this plant continues to look like it is blooming long after it is finished. In northern zones, it typically blooms from midsummer through early fall but in southern zones it starts blooming much earlier.
Its aromatic, bright green foliage grows into a densely compact, ball-shaped clump, much more refined looking than older cultivars. This is one of the easiest perennials to grow; it is drought tolerant, deer resistant, and attracts butterflies and hummingbirds like crazy.
