Campanula glomerata 'Superba' (Odessa)
In a trial of Campanulas by the Chicago Botanic Garden, 'Odessa' came out as a very prolific flowerer.
We've chosen this one out of 300 or so available because it exhibits some of the best qualities of the genus. A great cut flower, easy to grow given the right conditions, and the colour is gorgeous.
Campanula do spread but who wouldn't want more of this. Easy to lift and divide every few years.
