5 Washingtonia filibusta Seeds – Cold Hardy Hybrid Fan Palm

Washingtonia filibusta is a vigorous hybrid fan palm, resulting from a cross between the robust Washingtonia robusta and the hardy Washingtonia filifera. This variety is prized for its fast, upright growth and distinctive, deeply cut, fan-shaped fronds that create an instant tropical statement in any landscape. Its adaptability and striking silhouette make it a popular choice for gardeners seeking a bold, exotic look with reliable performance.
For ornamental use, this palm is ideal for creating a dramatic focal point in large containers, courtyards, or as a windbreak when planted in rows. It thrives in full sun and tolerates a wide range of soil types, including sandy and alkaline conditions, provided drainage is adequate. This plant is naturally drought-tolerant once established and grows best in USDA zones 8-11, with some protection in cooler regions during harsh winters.
