Chelone obliqua

Twisted Shell Flower

Twisted Shell Flower is a clump-forming perennial with upright stems and sharply veined foliage. In late summer, spikes of dusky pink to purple flowers rise above the leaves, giving height and colour. Medium in size and long-flowering, it thrives in moist soil and suits borders or bog gardens. So if you’ve wondered what will add late-season colour in damp Irish ground, this perennial is a strong candidate.
