Looking for a wonderfully showy flowering display that lasts and lasts at ground level? Easy-care Rozanne Geranium, (Geranium x 'Gerwat') features beautiful, 1-inch violet-blue blooms all the way through the growing season.

In 2013, the esteemed Royal Horticultural Society of Britain named Rozanne the "Plant of the Century". It took home the top title in the Chelsea Flower Show's 100-year history.

Rosanne is the most versatile, long-blooming, heat and humidity loving hardy Geranium you can buy! So...what's so special about Rozanne Geranium?

First, there's the bloom time. Deeply colored in shades of violet-blue, flowers with large white eyes begin appearing in late spring/early summer and keep coming in profusion until fall.

Many Geraniums fizzle in the heat and humidity of summer, but not Rozanne. This is a fantastic addition in borders and large patio containers in the South and Southwest.

Then there is the beautiful open, airy growth habit. Rozanne Geranium is more compact than most other Cranesbill Geraniums. It simply sends up more flowering stems in less space than other varieties.

This means you get a much bigger bloom show and the plant stays looking lush. It also has larger leaves and more robust growth than most Geraniums.

Oh, and the deeply cut leaves turn a nice, bronzy-red fall color, too. It will polish up the look of your plantings with ease.

This is a sterile, clump-forming plant. It won't set seeds or outgrow the mature spread listed on the Plant Hightlights.

You'll be very happy with the healthy, robust Rozanne Geraniums from Nature Hills. Order these award-winning beauties from us today!

How to Use Rozanne Geranium in the Landscape

This high-performance flower factory has a valuable, spreading growth habit that will softly fill the edges of your landscape. Add them in full sun or partial shade and enjoy blooms, blooms and more blooms!

Use them at the edge of your perennial plantings, or as a fill plant in wide, open areas as a spreading groundcover.

Create a solid display by planting them 12 inches apart. You'll measure from the center of one to the center of the next.

Stagger additional rows in a zigzagging pattern, as needed. Plant the new rows 12 inches apart, as well. Mulch between plants and keep them weeded as they fill in for you. It won't take long.

Tuck them around the edge of your large outdoor containers. You'll have a valuable "Spiller" that adds interest all season.

Create non-stop color and bold flower power in rock gardens and between pavers. Brighten up your foundation plantings. Add them in narrow new planting beds in front of mature evergreen trees.

#ProPlantTips for Care

For the best flower production, ensure that your chosen planting site receives at least 4 hours of sunlight a day. Rosanne performs best in well-drained soil. If your soil retains water, plant in containers or create a raised bed.

Trim last year's foliage down to a 1-inch length in early spring. Rosanne may evergreen in your hardiness zone. If so, gently rake out fallen leaves to tidy up at that time, taking care not to pull too hard.

Hardy Rozanne Geranium is a perennial, and will make you happy year after year. Order today, but please hurry. These award-winning plants sell out quickly!
