Opuntia humifusa plant with fruit

Opuntia humifusa or Prickly Pear Cactus is from eastern North America, from the northeast to Florida.

It is a striking plant with beautiful large flowers.

It is very hardy and can not be grown as a houseplant. It needs a very well draining soil and a spot in full sun.

Description:

It grows in clumps, up to 30 cm high.

The pads are green, 4-10 cm long and 4-6 cm wide. The glochids are yellow or brown, to 3 mm long.

The flowers are yellow, funnel-shaped, 4-6 cm long and flower in late spring. The harsher the winter, the more profuse the flowering.

The fruits are fleshy, purple or red, 3-5 cm long.

The fruits are edible as well as young pads.

This is the ideal cactus for beginners because of the ease with which it is grown, its frost and moisture resistance.

Usage:

The stems, fruits and seeds can be eaten. The stems are usually singed to remove the spines and are then roasted and peeled or fried. The leaf disks may be dried for later use. Fruits are eaten fresh or dried and may be used for jam or syrup. Seeds can be roasted and ground into flour. Indians used the slimy stem juice as a wound dressing.
