Introduction
Stately and distinctive, the Mexican Fan Palm is one of the most widely grown palms in
subtropical climates. The massive gray trunk is barrel shaped and ringed with old leaf scars,
and my reach over 3 ft in diameter. The leaves are stiff and their cottony threads fall off
with age. The petioles (leaf stems) of mature palms have curved thorns along the leaf margins.
Leaves should be removed or a “petticoat” will form from the crown to the ground. The blossoms
are white and yellow and produce an oblong or round red-black fruit about a 0.5 inch in diameter.
