How to Sow
Hardy geraniums prefer rich, well-drained, moist soil in full sun or partial shade.
How to Grow
These plants are easy to care for once they are established. Taller species may flop in the garden, but you can prop the plants up with twiggy-brush or let the plants flop and mingle with their neighbors. Either way, after the plants finish blooming, cut them back to a height of about 1", and they will produce a mound of new leaves within a few weeks. Hardy geranium plants often self-sow, but you can also propogate plants by division in the spring or fall.
Harvesting
Hardy geraniums make a lovely, light-textured, deciduous groundcover for partial shade. They are also effective in the front of the border, in a rock garden, as a woodland plant, or as an edging. Combine them with bellflowers, coral bells, Siberian iris, Shasta daisy, salvias or sages, and columbines. Combine shade-loving geraniums with hostas, astilbes, ferns, epimediums, and hellebores.
