Forming dense, spreading mounds of neatly cut leaves, Geranium himalayense, commonly known as Lilac Cranesbill, produces dainty, yet very large, cup-shaped flowers, elegantly borne on long stems, in shades of violet, indigo and blue from early to mid summer. Compact, its foliage remains attractive throughout the growing season and makes it useful as a low ground cover. Turning showy reddish-orange in fall, it creates a pretty contrast.
- Clump-forming and vigorous, this deciduous perennial reaches 9-18 in. in height (22-45 cm) and spreads 12-24 in. wide (30-60 cm). This sturdy performer is not only easy to grow, but it also requires very little maintenance!
- Performs best in full sun or part shade, in average, moist, well-drained soils. Tolerates full shade. Don't let the soil dry out! Native to the Himalaya, this Geranium likes cool locations.
- A perfect border plant, it is a spectacular addition to beds, borders, cottage gardens or underplanting roses and shrubs.
