Erodium glandulosum
Black-eyed Heronsbill
Zone 4 to Zone 9
Plant Shapes: Tuft

(Formerly Erodium petraeum glandulosum) Loaded with charm, this long-blooming plant forms a low tuft or mound of ferny olive-green leaves. Orchid-like flowers appear from late spring through to the fall, in a soft lavender shade with deep violet-black spots or eyes. One of the hardiest Heronsbill species, asking only for the excellent drainage provided by a rock garden, gravel scree or alpine trough. Divide clumps every 2 to 3 years in spring. Foliage is said to be fragrant. A cousin to the familiar Cranesbill Geraniums. Received a Royal Horticultural Society Award of Garden Merit (1993).
