COMMON NAME: Prickly Pear Cactus
OTHER COMMON NAME(S): Cactus Pear, Indian Fig, Old Mans Hand
SCIENTIFIC NAME: Opuntia humifusa
FAMILY: Cactaceae COMMUNITY: Secondary Dune
STATUS: Native
LIFESPAN: Perennial
HEIGHT: Usually prostrate
FLOWERING TIME: June-July
FRUITING TIME: Late summer
DISTRIBUTION: Eastern Ma.-west to Mn., south to Florida and Texas
IDENTIFYING CHARACTERISTICS: Jointed, pad-like, segmented, succulent
stems ~ large, showy yellow flowers ~ club-shaped, reddish-purple fruit
ripens in late summer
GENERAL INFORMATION: The succulent stems allow the plant to retain
water. The only native cactus found east of the Mississippi, the Prickly
Pear Cactus is found in the desert-like conditions of the secondary sand
dunes.
The pads and fruits are edible, though great care must be taken with the
spines. Even though they are so small as to often be invisible, they are
a painful skin irritant. The pads are a mucilaginous vegetable, similar
in texture to okra and are high in potassium and beta carotene. Cactus
candy can be made from thick strips of the pads. Boiled joints of
the western species are sold by street vendors in Mexico. The seeds can
be ground into a nutty flavored flour that is high in protein and oils.
The bitter sticky juice of the prickly pear can be used as emergency drinking
water. Prickly Pear Cactus is also grown as fodder for livestock. The
spines are removed by a flamethrower when used to feed livestock.
Please note: While harvesting wild berries/fruit is permitted at
Island Beach State Park, visitors must adhere to park regulations at all
times and must not damage vegetation or go off designated trails. This
