Seeds

Fresh, mature, tree ripened and dried seeds from trees that grow 5 miles from any other varieties of fan palms. 

These are the seeds of Washingtonia filifera (California Fan Palm). It is a shorter and fatter palm tree than Washingtonia robusta (Mexican Fan Palm). 

I planted about 50 of these last fall and they all sprouted. It took almost 2 months for them to sprout  - so be patient and water them regularly.

I live in the desert and do not have any other palm varieties within many miles of my house, so I am fairly certain that these seeds are true and not cross-bred.

Thanks

Washingtonia filifera (filifera – Latin "thread-bearing"), with the common names Desert Fan Palm, California-palm, Fanpalm, Petticoat-palm, Cotton palm, Arizona Fan Palm and California Fan Palm. It is a palm native to southwestern North America between an elevation range of 100–1,200 metres (330–3,900 ft), at seeps, desert bajadas, and springs where underground water is continuously available.

The specific epithet filifera means "thread-bearing."

Washingtonia filifera is the only palm native to the Western United States and 'palm iconic' California (although most palms known to Los Angeles and San Diego metro areas are W. robusta – and are easily confused by the layman with W. filifera) It is the largest native palm in the contiguous United States. The primary populations are found in desert riparian habitats at spring-fed oases in the Colorado Desert (Low Desert) and throughout a major portion of the Mojave Desert; with all populations extant in isolated disjunct populations throughout the stated regions. It has been introduced to populated portions near watercourses in the Sonoran Desert along the Gila River in Yuma, along the Hassayampa River and near New River in Maricopa County, and in portions of Pima County, Pinal County, Mojave County (along the Colorado River) and several other isolated locations in Clark County, Nevada. It is also known in northern Baja California of Mexico. It is an introduced, naturalized species in the warm springs near Death Valley and in the extreme northwest of Sonora (Mexico), and also in Florida and the U.S. Virgin Islands. As an ornamental tree it is cultivated in suitable temperate climates worldwide.

Washingtonia filifera grows to 18 metres (59 ft) in height (occasionally to 25 metres (82 ft)) in ideal conditions.

The fronds are up to 3.5–4 metres (11–13 ft) long, made up of a petiole up to 2 metres (6.6 ft) long, bearing a fan of leaflets 1.5–2 metres (4.9–6.6 ft) long. They have long thread-like white fibers and the petiole are pure green with yellow edges and filifera-filaments, between the segments. The trunk is gray and tan and the leaves are gray green. When the fronds die they remain attached and drop down to cloak the trunk in a wide skirt. The shelter that the skirt creates provides a microhabitat for many small birds and invertebrates. If there is any red color present on petioles or trunk its not a pure filifera but a fila-busta hybrid.

Washingtonia filifera is widely cultivated as an ornamental tree. It is one of the hardiest Coryphoidiae palms, rated as hardy to USDA hardiness zone 8. It will survive temperatures of −10 °C (14 °F) with minor damage, and established plants have survived, with severe leaf damage, brief periods as low as −12 °C (10 °F). The plants grow best in warm temperate climates with dry summers and wetter winters. Specimens outside of Mediterranean climates rarely exceed 15 metres (49 ft).

Washingtonia filifera can live from 80 to 250 years or more.
