A Top Geranium - Rozanne Fills The Bill
The geranium "Rozanne" was named Perennial Plant of the Year by the Perennial Plant Association, and for good reason. Any list of characteristics of this plant is a solidly positive list. You have to look hard for something negative and might have trouble finding anything.
Tough Standards To Meet - To have half a chance of being named perennial plant of the year, a plant only has to be easy to care for, pest and disease resistant, easily propagated, attractive through out the growing season, easily available in plant stores, and of course pleasing to the eye. Some perennials meet these standards, but many fall short in one category or another. Geraniums in general tend to satisfy these qualifications, and the geranium Rozanne certainly does that. Where most geraniums fall a bit short however, is once cut back after an excellent initial blooming period, the profusion of the blooms tends to deteriorate rapidly. Not so with Rozanne.
A Fine Companion - Rozanne has very attractive violet-blue blooms, which feature a white center. The blooms are typically 2" in diameter. Rozanne has a mounding growing pattern, reaching a height of about 2' maximum, and a spread of between 2' and 3'. It is perhaps at its best when planted as a border plant, but is also quite stunning when planted in masses. Many gardeners plant the geranium Rozanne in their rose beds, partially to hide the knobby legs of the roses, and partially for the interesting color effects that can be obtained. Rozanne is especially attractive when planted in combination with yellow flowers. It also goes well with other hybrid geraniums, when planted in among ornamental grasses, and with Shasta daisies, salvia, and with phlox. Its spreading characteristics make it a fine choice for window boxes and as a container plant.
Not Fussy About Soil, But Will Spread If You Pamper It - Rozanne is not particularly invasive, but if planted in rich soil, it will tend to start exploring, that is, sending out side runners. By clipping these runners off when they appear, you can keep Rozanne under control, and in the shape you intended. This hybrid geranium isn't terribly fussy about soil type, but as is the case with many perennials, if you start it out in a rich, well-drained, loamy soil it will be at its best, and live out its life as a low maintenance plant. You can plant Rozanne in partial shade or in full sun. This plant is very heat tolerant but will bloom more profusely in cooler climates. It is hardy in USDA zones 5-8.
A Patented Plant - The culivar geranium Rozanne is a patented hybrid, which means you can't propagate it for profit. Being a hybrid, you can't rely on the seeds give you a true culivar, if indeed they will sprout at all. Rozanne, like other geraniums, is easily propagated from cuttings or by division (don't sell your cuttings, it's illegal - giving one to a friend is not). Also, as is the case with the typical geranium Rozanne needs to be divided at least every 5th year, if not a year or two earlier. Most geraniums begin to spread out, leaving the center of the plant open when it approaches the time that they need to be divided.
Continuous Blooming -You can cut flowers from this geranium all summer, and the plant will blossom from mid-spring until late in the fall, as late as November in many areas. If it starts getting leggy, simply shear it back, and it will soon start blooming again, with the next bloom nearly as profuse as the last. Besides blooming all season, deer and rabbits seldom touch this plant, and it is very resistant to most pests and diseases.
In your search for the perfect geranium Rozanne looks like a winner.
