The Dark Violet Hybrid Skullcap is a popular, tough-as-nails perennial designed for low-maintenance landscapes and rock gardens. It is a human-made hybrid—a cross between the pink skullcap and the resinous skullcap. It produces a massive profusion of tiny, snapdragon-like blooms in an intense, neon violet-purple. The leaves are small, oval, and often a velvety gray-green, which provides a beautiful "cool" contrast to the vivid flowers.
