Best vibrant addition for gardeners seeking reliable, healthy flowering plants.

Its fern-like foliage provides a beautiful contrast to the blooms. This perennial is well-suited for rock gardens due to its preference for well-drained soil and average to fertile conditions. It requires protection in winter with mulch or dried leaves. While generally disease-resistant, it can attract slugs. This plant is not recommended for hot and humid Southern climates.
