With over 400 species and hybrids, hardy geraniums are low-maintenance plants, easy to grow and provide a wide selection of colors. All have palmate leaves, 5-petaled flowers, and seed pods shaped like a crane's bill. Hardy cranesbill could be tall, shrubby plants, or ground covers; most species are slow growing though some are considered invasive spreaders. Some will sow seedlings; others are best propagated by division.
Most geraniums prefer average to rich, moist but very well-drained soil in full sun to part shade. Many varieties are somewhat drought tolerant, but not particularly heat tolerant, so afternoon shade is often recommended in warmer zones.
Blooms usually emerge in May or June, and can last through fall. If flower production fades in hot summers, foliage can be sheared to start a new flush of foliage and blooms.
