Plant Details

This group of plants combines handsome foliage with showy flowers. Double, semidouble, or single blossoms in red, orange, pink, or yellow appear through- out the summer if plants are deadheaded regularly; they make good cut flowers. Leaves of most are divided into many leaflets, often with scalloped or toothed margins. Geums are not suited to extended summer heat. They'll grow in the Middle South, but they prefer the Upper South and higher elevations of the Appalachians, Blue Ridge Mountains, and Ozarks. Soil should be consistently moist and, except for G. rivale, well drained. Start from seed sown in early spring, or set out transplants. Divide established plants in fall or spring. Deer resistant.

G. 'Alabama Slammer'. This hybrid forms a clump of light green leaves 14 in. high and 10 in. wide. Ruffled, single or semidouble flowers up to 1 in. wide are multicolored: golden yellow marked with red and orange. Stems and calyxes are deep burgundy.

G. chiloense. CHILEAN AVENS. Best-known species. Native to Chile. Mounding foliage clumps to 15 in. high, 2 ft. wide.
