Rozanne is a spectacular hardy geranium. It is one of the best hardy geraniums ever - far superior to the formerly much planted Buxtons Blue. Is has a very long flowering time - here it starts blooming in the middle of may and does not stop until the first real frost days in November. It was a seedling found in the garden of Donald and Rozanne Waterer in 1990, but first introduced in 2000 by Blooms of Bressingham in England.
Another hardy geranium; Jolly Bee was introduced in 2003 in Holland/Netherlands by Hybridizer Marco van Noort - it is said to be a found seedling. Jolly Bee has become very, very popular in many gardens all over the world. No wonder since it has outstanding vigor and and produces a mass of rather large flowers for a very long time.
But many who grow Rozanne and Jolly Bee, have found it very hard to see any differences between to 2 geraniums. It has raised speculations whether Jolly Bee is an imposter and really is Rozanne. There has been some heated discussion about the issue!
Rozanne has been been chosen as the "Perennial plant of the year 2008" and Jolly Bee is a Proven Winners selection. I highly recommend both of these - they are hardy to USDA zone 5 and are wonderful companion plants for roses or in mixed borders. Both get quite big - about 1 feet tall and up to 4 feet wide. It can be trimmed if it becomes too leggy, and will keep flowering. It is actually interesting to grow both - I have 3 Jolly bees and 2 Rozanne - and I can not tell any difference. Jolly Bee may be more bushy and vigorous - but that could be a coincidence. Both are great garden plants and I love the blue flowers and the green leaves with yellow marblings. It is not hard to see why they have become so popular:
