LOUISVILLE, KY (WAVE) - Perennials are great because they stay beautiful for most of the year. WAVE 3 garden expert Cindi Sullivan says one kind of perennial is getting some special recognition.
The Perennial Plant Association is a national group that chooses a standout perennial annually to designate as their perennial plant of the year. This year's selection is the new (and true) hardy geranium called Rozanne.
Also called cranesbill geranium, hardy geraniums are generally great garden plants for the front of a border, they are also excellent for massing or in mixed containers. They have a long-season display of flowers.
Rozanne is a big plant for a hardy geranium, with bright blue flowers that bloom all summer long, showing great color until frost. It forms a midsized mound of deeply-cut green leaves, bearing loose clusters of bright violet-purple cup-shaped flowers starting in early summer.
Plants have large leaves and form mounds about 18-24 inches tall. Flowering can continue for weeks or months. They will grow in full sun or part shade.
If flowering of your hardy geraniums lags during hot weather, simply prune back by half to rejuvenate. But I can almost guarantee that you won't have to do this with Rozanne. The foliage will also turn a bronzy fall color which will add to the interest.
