Rozanne Hybrid Geranium

Rozanne Hybrid Geranium item #11913


Perennial geraniums are floriferous hardy perennials with compact, spreading habits. They are excellent for massing, edging, groundcovers, and in pots or mixed containers. Most varieties are hardy in zones 4 to 8, and a few (like the Jolly Jewel varieties) are hardy to zone 3.

How To Grow

Plant bare root Geranium in spring 4 to 8 weeks before the last frost by preparing a hole large enough to fit all the roots without bending them and mix in compost or other organic matter. Plant with crowns ½ to 1 inch below soil level.


Easy-to-grow, low-maintenance plants for for full sun to part shade in fertile, moist, well-drained soil. In hot, humid climates, plants can be cut back by a third to promote new growth if flowering declines.

Fertilizer Recommendations

Geraniums are moderate to heavy feeders and benefit from regular fertilization. Use full rates of ALGOplus Flowering Plant 4-6-7 liquid fertilizer or Neptune Fish & Seaweed Fertilizer 2-3-1

Common Problems

Usually trouble-free. Japanese beetles sometimes attacks plants. Leaf spot powdery mildew are rare problems. Rabbits occasionally feed on plants. Use Captain Jack's Deadbug Brew if Japanese beetles are a problem. Diseases can be treated with 70% neem oil.

Alternative Products

Other low-growing flowering perennials include scabiosa, dianthus, and gaillardia.

Product Recommendations

Geraniums combine well with foliage perennials like Silver Mound artemisia or ornamental grasses.
