A classic cottage‑garden perennial producing masses of rich scarlet, semi‑double flowers from early summer into autumn. Upright, wiry stems rise above a neat mound of fresh green foliage, giving long‑lasting colour at the front of borders. Loved by bees and carrying the RHS Award of Garden Merit, it’s reliable, easy to grow, and thrives in full sun or light shade. Perfect for adding vibrant, fiery colour to mixed borders, with blooms that also work beautifully in informal cut‑flower arrangements.
