Washingtonia filifera – California Fan Palm Seeds

Washingtonia filifera, commonly known as the California fan palm or desert fan palm, is a robust, slow-growing palm with a thick, columnar trunk that can reach 15–20 meters (50–65 feet) in height and 0.6–1 meter (2–3 feet) in diameter. Its crown is filled with large, fan-shaped leaves measuring 1–2 meters (3–6 feet) across, with light green blades and long petioles that feature orange-brown fibers. The dead leaves often form a dense, shaggy “skirt” around the upper trunk, adding to its distinct appearance. It produces small white flowers in hanging clusters, followed by black, berry-like fruits.

Native to the desert oases of the southwestern United States and northwestern Mexico, this palm is highly drought-resistant and thrives in sandy, well-drained soils. It is more cold-hardy than its relative, Washingtonia robusta, tolerating temperatures down to -10°C (14°F). Additionally, it has good wind resistance, making it well-suited for arid climates and landscaping in areas prone to occasional frosts. This iconic palm is a symbol of desert landscapes and is valued for its resilience and dramatic form.
