Soapweed (Yucca glauca), also known as Soapweed Yucca or Narrowleaf Yucca, is a striking semi-woody perennial that adds a unique architectural element to your garden with its clumps of narrow, pale-green, dagger-like leaves. A member of the Agave family, this plant is well-adapted to dry, arid climates. Though it may take many years to flower, the effort is well worth it, as a spectacular flower stalk emerges, bearing bell-shaped, greenish-white flowers that are followed by woody seed capsules.
Soapweed Yucca is an essential plant for supporting native ecosystems. Its leaves provide year-round interest and its flowers attract butterflies and beneficial insects, but the plant's true ecological value lies in its co-dependent relationship with the Yucca Moth, which is the sole pollinator of its flowers. The deep taproot, which can extend up to 20 feet, makes it exceptionally drought-tolerant and a resilient choice for challenging landscapes.
Native to the southwestern US, this plant is the New Mexico State flower.
