The well-known California Fan Palm is without doubt the stateliest of all our palms whether native or introduced. It delights in a good soil, deep and well drained, and a plentiful supply of water at the root during the growing season.
Washingtonia filifera is not recommended for cold exposed situations in San Francisco, the Summer being too cold for its making vigorous growth, but south of San Francisco and in the interior counties as far north as Butte county it is perfectly at home and grows vigorously. Washingtonia Sonorae is much more hardy, growing well even in San Francisco.
Propagate by seeds sown, in early Spring, one-half inch deep under glass and kept in pots until one year old; they may then be planted in the nursery and left there until large enough to be planted in their permanent quarters.
