General Description

Ornately lobed leaves create a pretty base for the magenta and black-eyed flowers high above the Red Admiral cranesbill. Blooming occurs from midsummer to fall, this hybrid perennial is an upright, clumping plant requiring little maintenance.

The stems and rounded, deeply dissected leaves of this geranium are bright medium green and hairy. In late fall the leaves turn shades of red and yellow. Its delicate flowers first appear in summer and continue into fall. The five-petaled blooms are a vibrant magenta with red-violet undertones; the center is black. The dry, brown fruits are shaped like bird's beaks and filled with seeds.

Grow ‘Red Admiral' in full to partial sun and average garden soil that is humus-rich, moist but well-drained. It is tolerant of alkaline soils and in hot summer regions light shade is best. The foliage may begin to look ratty in hot summer weather. If this happens, trim back the old to allow a flush of new leaves and to coax it to rebloom in fall. This perennial is best placed in sunny perennial or ornamental grass gardens. This cultivar may self-sow and such offspring will not necessarily be true to parent.
