The Perennial Plant Association's 2008 plant of the year is Geranium 'Roszanne' (Rozanne cranesbill geranium). Large, jewel-tone, violet-blue flowers combined with deep green, lightly marbled foliage and an extended season of interest make Geranium 'Rozanne' an ideal perennial for any garden.

The 20-inch high Rozanne geranium mounds to a 24-28 inch spread. It thrives in full sun to partial shade (afternoon shade is advisable in hot climates) in moist, well-draining soil. It boasts exceptional heat tolerance and drought tolerance among the geraniums and is hardy in zones 5-8.

To maintain peak appearance, gardeners should shear back old foliage to 3-inches in August to promote new growth. Side branches may be removed to control spread.

No insect or disease pests are known to attack Rozanne.
