'Max Frei' Geranium (Geranium sanguinem 'Max Frei') is an easy-to-grow perennial geranium with reddish-purple flowers and deeply lobed dark green leaves that turn reddish in fall. It likes full sun to part shade and medium-wet soil. It grows to 9 inches tall and 24 inches wide with a beautifully compact habit that makes it perfect for rock gardens and small borders. It's sometimes called Bloody Cranesbill for its fall foliage color and crane-like seedheads.
