Geranium phaeum

Geranium phaeum makes a great background plant & filler of space in lightly shaded areas.  It is fairly tolerant of dryness.  It's a pretty plant with a profusion of dark blue, purple or black flowers in April & May.  Black flowers suggest the common name Mourning Widow.  Geranium phaeum is taller than most  species.  It grows to a height of nearly 2 feet when in flower.  The flower spikes with seed pods are also attractive.  There is no need to cut them back after bloom has faded.  The leaves are pleasing in form.  Some have nice purple blotches, like the cultivar 'Samobor'.  Geranium phaeum is native to Europe in the Pyrenees & Alps in subalpine meadows & forests.  This is a good candidate for dry, light shade.
