Geranium pratense 'Midnight Reiter' is a striking hardy geranium, grown for its rich violet-blue flowers set against dramatic dark purple to near-black foliage. Flowering in early to mid-summer, it forms an upright, clump-forming perennial that adds strong colour contrast to borders. Fully hardy and easy to grow, it thrives in sun or light shade and is well suited to cottage gardens and contemporary planting schemes.
