Geranium sanguineum 'New Hampshire Purple' is a compact, low-growing hardy geranium, producing rich purple-magenta flowers in early to mid-summer. Free-flowering and robust, it forms a neat, spreading mound of finely divided green foliage that often develops attractive red tones in autumn. Ideal for sunny borders, rock gardens, and ground cover, it is fully hardy, easy to grow, and very low maintenance.
