Geranium

Wildlifelover

Morning,

Earlier this year, I bough two of these geraniums which were labelled as ‘Johnson’s Blue’ but they don’t look like the other Johnson’s Blue I have. 

The have grown massively and are swamping other plants in the bed. 

I have two questions please; would anyone know which variety of geranium these are and, as they are taking over the bed, am I ok to cut it back now and then just to give the other plants some space or won’t the other plants (Cirsium rivulare ‘Agropurpureum’ and Aster amellus ‘King George’) mind?

Many thanks.

When they form big clumps you can just pull sections away to give space to other plants.

I can't advise about the variety, but l'm pretty sure that it's not Johnson's Blue. If they're taking over so much that you don't want to wait for them to flower, and they're in the wrong place, l would cut them back now and replant them in new positions (or pot them up). Keep them watered and they will start to shoot again within a matter of weeks. 
Geraniums  are pretty much indestructible l find.

Definitely not Johnson's Blue. There are so many varieties that it's impossible to be sure, but yours looks a lot like this one https://www.seedaholic.com/geranium-bohemicum-orchid-blue.html

Many thanks everyone, I’ve cut it back a bit near the middle of the bed to give the Asters some space.
