Abstract
A new and distinctive cultivar of Shrubby Potentilla, botanically known as Potentilla fruticosa, is provided. This cultivar can be distinguished from other Potentilla cultivars by its large clear semi-double deep pink flowers of long flowering duration, superior foliage quality, and plant growth habit. Attractive pink flowers commonly are exhibited from the summer until the time of frost. A medium-sized compact round and spreading plant having deep green foliage is formed that tends to hold its foliage well even at the base of the plant. The new cultivar is an attractive landscape plant that is suitable for growing in a wide range of climatic zones. Good plant performance is possible even under hot and dry growing conditions where other pink-flowering cultivars of the same species have tended to perform poorly.
