Geranium phaeum (Dusky Crane's-bill) is a hardy, shade-tolerant perennial with elegant, deep burgundy to purple-brown flowers in late spring and early summer. Ideal for woodland gardens and shaded borders, it forms neat clumps of soft, lobed foliage and thrives in moist, well-drained soil. Low maintenance and wildlife-friendly, it's a reliable choice for naturalistic planting schemes.
