 Common Name: Geranium-Hardy
Common Name (Alternative): Cranesbill

Huge, glowing violet blue, saucer-shaped flowers with distinctive white eyes and reddish-purple veining are held above mounds of deep green foliage that is slightly marbled with chartreuse. Geranium 'Rozanne' is one of the longest blooming perennials in the garden. It is an amazingly free-flowering cultivar as its flowers are sterile; it keeps the blooms coming from late spring into mid-fall.

Leave plenty of room to grow this wide spreading perennial. In one season, one vigorous plant will cover a 2-3 sq. foot area. It looks especially nice when complimented by yellow or chartreuse flowers or foliage.

Hardy geraniums are wonderful filler plants for any landscape, either residential or commercial. They blend nicely with most other perennials and offer continuous color throughout the summer months.

Homeowner Growing & Maintenance Tips:

Cranesbill is generally quite adapatable to a variety of growing conditions. Though it prefers moist, well-drained soil, it will also tolerate periods of drought once established. For this reason, it is a good choice for southern gardens.

Cranesbill will grow in full sun or part shade. In too much shade, however, its habit will be less compact and fewer flowers will be produced.

Geraniums are generally considered pest free. They require little care once established. If the foliage begins to look raggedy by late summer, simply trim it back. A new flush of foliage will quickly take its place.
