There are many of the so called blue geranium. Most of them are in fact violet and all of them desirable. This is one of the best. Deep violet flowers over a long period and beautiful soft velvet green foliage colouring up in autumn. I grow it in full sun here but it may require some afternoon shade in hot districts.
Over the winter months I will be able to dig rhizomes from this Geranium and post bare rooted.
