New Hampshire Purple Hardy Geranium

Geranium sanguineum ‘New Hampshire Purple’ is a compact hardy geranium grown for deep, vivid magenta flowers over lobed green foliage. Its documented mature size is about 8 to 12 inches tall and up to 18 inches wide, making it a useful front-of-border perennial and a low cover between taller plants. ## Placement and season Set plants in full sun or partial shade, with enough room for the foliage to spread. The Morton Arboretum notes the cultivar’s magenta flowers and compact dimensions; its bloodred geranium guide describes the species as a low ground cover that flowers from late spring into midsummer.

Full sun is also tolerated. Avoid waterlogged sites. The lobed foliage provides a green ground layer after flowering; red fall color is characteristic of bloodred geraniums.

Divide established clumps when they outgrow their allotted space. Check neighboring plants as the clump broadens, and allow room for its measured spread rather than crowding it against small companions.
