Fremontodendron decumbens, commonly known as Pine Hill Flannelbush, is a semi-deciduous shrub native to the chaparral and foothills of the Sierra Nevada in California. It is a rare species, typically growing up to 3 feet tall with a sprawling habit. The Pine Hill Flannelbush is known for its bright yellow, cup-shaped flowers that bloom in the spring and are quite showy, attracting various pollinators. The leaves have a flannel-like texture, which is where the common name is derived from.

In cultivation, Pine Hill Flannelbush is valued for its drought tolerance and vibrant floral display, making it an excellent choice for native plant gardens, xeriscaping, and as an accent in rock gardens. It requires full sun exposure to thrive and prefers well-drained, rocky soils, mimicking its natural habitat. While it is low-maintenance once established, it does not tolerate overwatering or heavy, clay soils. Gardeners should be cautious as the plant’s foliage can cause skin irritation in some individuals. There are no major disease problems, but root rot can occur in poorly drained soils.CC BY-SA 4.0
