The Washington Palm or otherwise called the Mexican Fan Palm has traditionally been more widely grown in Florida than its close relative, the California Washington Palm, probably because of its faster growth rate. Hybrids between the two species occur, and many specimens in landscapes in both Florida and California are likely of mixed ancestry. Though a desert palm, the species lives nearby permanent surface or sub-surface water, and faster growth occurs with periodic age. The Washington Palm loses some of its appeal as the trunk tapers and thins. In Florida, lighting commonly ends the landscape life of this palm as soon as it begins to tower over surrounding vegetation. It is the tallest growing of the hardier palms. |
