Geranium 'Rozanne'

I decided to try some Rozanne this year after reading so many good things about this 2008 Perennial of the Year. I have to say that I have been very impressed. All of my plants started blooming within weeks of being planted (unusual for most perennial flowers) and have bloomed non-stop all summer into fall. Doesn't need any deadheading either. Seems to spread rapidly but is not at all thuggish - grows and creeps low to the ground around other plants. The best part is the beutiful shade of lavender blooms. Very stunning!

I planted two of these a year ago from tiny seedlings bought at a nursery. They are each 5 feet wide this year. They have a nice color and long blooms, but they have completely taken over the beds they were planted in.

I have grown this geranium for a year with success in southern California. It is a hybrid of two older geraniums - G. himalayense and G. wallichianum, both of which are rated for USDA zones 4-10 and up to 24 in Sunset zones.

The filing date for the patent is 1999 PP12175 It was originally spotted in 1990 by Donald & Rozanne Waterer in their personal retirement garden in Somerset. They nurtured the find, then offered it to Adrian Bloom of Blooms of Bressingham in 1992 for commercial development. It was released to the public for the 2000/2001 gardening seasons.

This is one of my favorite plants - it has blooms even in December. Very happy blue, blooms repeatedly all summer and trails for 2-3 feet. Easy care.

In last year's miserable drought, this bloomed endlessly. A definite winner.

This plant was named 2008 Perennial plant of they year by the Perennial Plant Association

I've had two of these plants for about 6 years now. They are faithful returns in the spring and do bloom beautifully. Mine are getting really too big for the space they are in and I'm wondering how to go about splitting them? Do I just dig them up in the spring and chop the root ball in half or what?

It does get larger than its tag states, but since it has this great weaving habit, I placed it in a spot where its neighbors (hosta, lupine) were accidentally planted too far apart. Rozanne fills in the gaps between the plants perfectly. It's not dense, but not untidy or rangy either. It just creeps along the ground wherever there is room, blooming its fool head off.

If you wanted a mound, you could probably plant a few together and let each build the others up.

The flower color changes depending on the weather. Sometimes, when it's cool, it's as blue as any other "blue" flower. When the weather gets warmer, it's more purple. It adds another point of interest to an already beautiful plant.

Mine is growing in a mostly shady area, in slightly amended NJ clay.

Medium 20" - Plant 24" apart. zone 5-8. Extremely long blooming - even through the heat of August. Mounded, slightly marbled foliage turns attractively red in fall. Very heat tolerant. Flowers are deeper blue. Will spread to fill in with moist organic soil.

This is the second summer for mine, and it has been unbelievable! Last fall it was still blooming strong when I was putting my Halloween pumpkins out on the porch, I was actually ready for it to stop! This year it has bloomed non-stop. The only thing is, it gets A LOT bigger than the stated size, mine right now about 36 inches across, plant it in a spot where it will have lots of room!

Blooms of Bressingham selection. Vigorous grower with deep green foliage which performs well even in the heat of southern summers and blooms right through until frost.

Yes, what a grower! Mine (2) get just a few hours of Denver sun, but interweave with other plants and drape gently over some groundcovers without smothering. Perhaps they are lankier than usual, but they bloom like crazy. Lovely with orange columbine, Aquilegia desertorum, in my ornage and purple section. Also really nice covering over a bulb bed, and the fall-bloooming Crocus speciosus or colchicums will look great popping through!

I agree with the others' comments and would only add that it's a good thing it's so beautiful and long-blooming, because it spreads like crazy! It has pretty much monopolized a wildflower garden I created in my front yard. And "yes", it makes a delightful combination with coreopsis.

This is one of the best Geraniums to come along in years!!! Very crisp, clean apple green foliage which has amazing fall color. The flowers are an almost unreal blue, and are so very plentiful. Long bloom period, and nice overall habit makes this a definite must have!!!

I planted geranium 'rozanne' from White Flower Farm this spring. It has bloomed well all summer and is still going strong in late September. I put it around groups of Coreopsis 'creme brulee' for a fantastic purple and yellow combination. Highly recommended.
11/21/04: still blooming but leaves have turned fantastic colors . I'll be ordering more for next season to go in my rose beds.

This is a hybrid of G. himalayense x G. wallichianum 'Buxton's Variety'
