Most varieties thrive best in moist soil, so it's a good idea to incorporate organic matter when planting them, to help conserve moisture. A spot in partial shade is ideal, as the foliage can scorch in full sun.
As for colour, geum flowers provide some of the richest hues available, from deep reds to custard yellows. Try growing geums with plants like Japanese primroses, daylilies, ragged robin and white laceflowers.
