Perennial Geraniums (not to be confused with Pelargoniums) regrow every year after dying back in the autumn and winter. They are also known as cranesbill I think because they sometimes have a prominent pointed central part to the flower (can’t remember what that bit is). If you want ground cover this is a great plant.

We bought two plants ten years ago from the Dorothy Clive Garden and now they are all over the garden. You can cut them back after they have flowered and they might have a second flush of flowers. The bees love them.

We have them planted under the trees in the shady part of our garden. If you look them up on the Internet you can find many different varieties.
