Legal action by Blooms of Bressingham has led to the withdrawal from sale, by Marco Van Noort, of Geranium 'Jolly Bee'. There is a very interesting resume of the whole story at the link here:

For what it is worth: I have grown Geranium 'Jolly Bee' since it was first introduced and have always said it was difficult to distinguish from G. 'Rozanne', which I have also grown, however for me 'Jolly Bee' was the better plant of the two. If you would like this plant we now sell it under the name Geranium 'Rozanne'.
