Geranium ‘Havana Blues’: Long flowering new cranesbill

Posted by Graham Rice on 06 Dec 2011 at 12:49 PM

Geranium 'Havana Blues' - a new long-flowering hardy geranium. Image © Marco van NoortWith new hardy geraniums appearing constantly - twenty newcomers in the 2011 RHS Plant Finder alone to add to the many many hundreds already available – it’s understandable when gardeners are cautious about yet another new one.

But when one of the world’s top breeders of new hardy geraniums introduces a new variety we should pay attention and in ‘Havana Blues’, Dutch breeder Marco van Noort looks to have a winner.

“‘Havana Blues’ is special because it has big and nice blue flowers with dark veins,” Marco told me. “At first the plant sprouts with greenish yellow leaves and that is unusual for this type of plant. It starts to flower around May/June and doesn't stop until the first frosts come. It likes sun to half shade and grows 30-40 cm tall and 40-50 cm wide. I can't compare it with another Geranium, it’s is not a look-a-like of anything else”.

Marco explained that every year since 1993 he has raised seedlings of forms of Geranium wallichianum and selected the very best. He is especially interested in plants with a very long flowering season and is also looking for new forms involving G. sanguineum and G. cinereum. He is also working on new varieties of echinacea, astrantia and other hardy perennials.

Geranium ‘Havana Blues’ is available from these RHS Plant Finder nurseries and is also available from Hayloft Plants.
