General Information

Opuntia spinulifera is a usually spiny, evergreen, succulent tree-like cactus with segmented stems and numerous branches arising from near the base; it can grow up to 130cm tall. Individual stem segments are obovate to round, 20 - 25cmlong and 15 - 20cm wide[].
The plant is commonly harvested from the wild for its good quality fruit, it is encouraged in thewild and sometimes grown in home gardens[, ].
The plant is sometimes cultivated and has become naturalized in countries such as Argentina and South Africa.

Known Hazards

The plant has numerous minutely barbed glochids - these are barbed spines that are usually small to minute and are very sharp and brittle. The glochids are very easily dislodged when the plant is touched and can penetrate the skin where, because of their barbs, they become stuck and are very difficult to see and remove. They can cause considerable irritation and discomfort[, ].
Opuntia species can contain quite high levels of oxalic acid, especially in older parts of the plant. Perfectly alright in small quantities, foods containing oxalic acid should not be eaten in large amounts since it can lock-up other nutrients in the food, especially calcium, thus causing mineral deficiencies. The oxalic acid content will be reduced if the plant is cooked. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition[, ].

Cultivation Details

In cultivation, Cactus plants generally will not succeed in moist climates. They usually require a sunny position in a well-drained, circumneutral soil and to be kept more or less dry in the dormant season[].
The mature fruit is persistent on the plant, it has been observed to remain on the cladodes for 12 months or more in edible condition[]

Edible Uses

Fruit - raw or cooked. Of good quality[]. The short, globose, cylindrical to ovoid, yellowish fruit is 4 - 5cm long[].
The fruits of this and several other Opuntia species are known as 'xoconostles' in Mexico, where they are valued for their more acid flavour and are often consumed, though more as a vegetable and flavouring than as a raw fruit[]. A common recipe is to slice and mix xoconostles with tomatoes, onions and hot peppers. Adding diced xoconostle to salsas gives them a special zesty acidic flavour, whilst they can also be used as a base for refreshing drinks[].

The tender young stem segments of various species are often cooked as a vegetable[]. Known as ‘nopals’ in Mexico, where they are a common ingredient in numerous dishes, they can be eaten raw or cooked, used in marmalades, soups, stews and salads. The most commonly used species are Opuntia ficus-indica or Opuntia hyptiacantha (syn Opuntia matudae), although the stems of almost all Opuntia species are edible[, ].
