Calycadenia villosa

Dwarf Western Rosinweed is a compact perennial with bright yellow flowers, native to western U.S. regions.

Also known as: Dwarf Western Rosinweed

Calycadenia villosa, commonly known as Dwarf Western Rosinweed, is a perennial herb native to the western United States, particularly found in California and Nevada. This species typically grows to a height of 30 to 60 centimeters, forming a compact, bushy habit with numerous branching stems. The leaves are narrow, linear, and covered with a fine layer of hairs, giving them a distinctive texture. The flowers, which bloom from late spring to early summer, are bright yellow and resemble daisies, attracting various pollinators such as bees and butterflies. The fruit is a small achene, which aids in wind dispersal, allowing the plant to colonize new areas effectively.

Ecologically, Dwarf Western Rosinweed plays a significant role in its native habitat, providing nectar and pollen for insects while also stabilizing soil with its root system. It is well-adapted to dry, rocky soils and can tolerate drought conditions once established. This species has been used in traditional medicine for its anti-inflammatory properties, and its attractive flowers make it a candidate for ornamental gardening. Its hairy leaves and stems help reduce water loss, making it resilient in arid environments.
