hardy geraniums are herbaceous perennials. It means they die down during winter but come back in the spring. They are very reliable plants and grow well in sunshine (if it is not too hot where you are) or they will do better in filtered sunshine.
There are hundreds of varieties with varied flower colour and leaf shapes.
That was what I thought. I am starting a shade garden that has some border sunshine and nice dappled sun areas - was hoping to use some of these. Does anyone know offhand which have the largest flowers? Are there any scented varieties?
