Woolly Bird’s-Foot Trefoil: A Charming California Native for Water-Wise Gardens

This delightful perennial forb brings a unique combination of silvery foliage and cheerful yellow flowers that can transform any water-wise landscape.
What Makes Woolly Bird’s-Foot Trefoil Special
Woolly bird’s-foot trefoil is a true California native, found exclusively in the Golden State. This perennial forb gets its common name from its distinctive woolly, silvery-gray foliage that creates a lovely textural contrast in the garden. The plant produces clusters of small, pea-like yellow flowers that add bright pops of color against the soft, fuzzy leaves.
