Yellow Pincushion is an annual wildflower native to California and Baja California that blooms from March to May. It has slender, branching stems up to 2 feet tall covered in gray-green leaves. The small, golden-yellow flower heads are showy when massed together. Yellow Pincushion thrives in full sun and well-drained soil, providing an excellent nectar source for butterflies. It is a sensible choice for native gardens and containers as a substitute for non-native yellow sunflowers.
