Coccothrinax proctorii

Geoff Stein - Author & Editor

Pronunciation: coe-c0e-THRIH-nax prock-TOR-ee-eye


Common Name: Cayman Thatch Palm; Proctor's Silver Palm

Chamaedorea proctorii is a fairly rare species for California, but one that seems it might be OK in the right climates. In the wild, this is a palm with a fairly stout, clean trunk, short leaves with a pronounce droop to them and very silvery in color at last on the ventral surfaces. Currently there are no mature palms in California. Like all Coccothrinax, this is not a fast growing palm in California
