Geranium sanguineum 'John Elsley' is a bold and floriferous hardy geranium, producing large, rich magenta-pink flowers with darker centres in early to mid-summer. Slightly more vigorous than many sanguineum cultivars, it forms a dense, mound-shaped plant with 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 long-lived.
