Growing Notes

Fast-growing, and especially well-adapted to California conditions. Apply palm food (3-2-3 with micronutrients) quarterly (OK to skip winter fertilizer application). At maturity, its garlands of thousands of flowers make pollinators and gardeners happy.

Special Interest

First identified in a garden in Riverside, California, in the mid-20th century, this variety has never been identified to species. Some believe it to be a strain of Sabal mexicana from the southern portion of its range. Others see resemblances to the notably large Caribbean species, Sabal causiarum and Sabal domingensis.
