A compact and attractive form of the native Alisma with more rounded leaves. When mature this plant sends up numerous flower heads with multiple delicate pinkish-white petals. Likes to be kept constantly moist. Remove flower heads soon after flowering to encourage new flowers and prevent self seeding. Trim old foliage after dying back in Autumn Plant in full sun to partial shade between 0cm and 15cm deep. Flowering period: June to August Mature height: 60cm to 90cm Growth rate: slow Reviews There are no reviews yet.
