The Prickly Pear

Blind-Eye Prickly Pear

Opuntia is a genus of cactus which produces a sweet studded fruit–the prickly pear. Like all true cacti, the Opuntia genus comes from the Americas. Opuntia plants are naturally occurring from Connecticut and Long Island west to Chicago and southern Canada! More and more species can be found growing in the American southwest down into Mexico (where the greatest diversity of Opuntia species are found). Varieties of the plants also grow naturally throughout Central America, the Caribbean, and down into South America (although “naturally” might be the wrong word—the peoples of the Americas have been instrumental in the spread of these plants for a long time).

Opuntia plants consist of large flat green pads which have two sorts of spine. There are long sharp hard spines capable of drawing blood & causing serious injury, but also, more insidiously, there are infinitesimal hairlike prickles called glochids. If touched, these glochids feel like fur but the microscopic ends break off and penetrate the skin where they prickle agonizingly. Argh! Just writing about them is making me itch.

Prickly pears are incredibly hardy plants which are resistant to drought, disease, and animals. They easily grow into great clonal colonies which people sometimes use as a sort of natural fence. In the sixties, Cuba planted a prickly pear wall all around the American military base at Guantanamo Bay so that fleeing dissidents would be unable to seek shelter there.

However it is not for its spines, its toughness, or its prodigious ability to grow that the prickly pear is principally known, but for its sweet colorful fruit. These cactus fruits are colloquially (but wrongly) known as “pears” or “figs” in English (and endless other names in many, many other languages). The fruit are filled with delicious juice, tasty flesh, and hard but edible seeds. The fruits have only modest amounts of essential nutrients (particularly fiber, vitamin C, and magnesium), but they are filled with phytochemicals–a catch-all term for molecules made by plants which may have biological/medical significance. Scientists believe prickly pear fruit may be beneficial for mitigating the negative health consequences of diabetes, high cholesterol, and obesity (and hangovers too). Additionally, certain prickly pear phytochemicals may have antiviral and anti-inflammatory properties. There were lots of ambiguous words and conditional phrases in there. I don’t know what to tell you…Medical science is working on it, but they have a lot on their plate.

Whatever the health benefits, prickly pear is delicious and it grows in places where other things do not. This means the plant has been imported to Australia, Asia, Africa, the middle east, and many other places. It is easy to grow, and hard to kill, so prickly pear is (quietly) one of the great invasive species of the time. Since it has mostly established itself in forsaken deserts where nothing was growing anyway, nobody is particularly worried…for the moment. Did I mention forsaken deserts? The prickly pear is particularly at home in Israel and Palestine where it has become an integral part of both cultures. I was first shown how to cut open and eat prickly pears by a Jew who said that hardened native-born Israeli Jews who farm the desert call themselves “sabras” (the modern Hebrew term for the fruits) because they are spiny and tough on the outside but sweet and generous in their hearts.

I really like prickly pears and I have been wanting to make a bunch of prickly pear ice cream custard. I will let you know how this project goes…I have the feeling it is going to turn into a big hilarious magenta mess, so stay tuned for that!

Succulent Gardens

Sheilam Cactus Garden (South Africa)

Oh, there are all sorts of gardeners! Some people tend sugar plantations or farm huge monocultures of wheat whereas others raise variegated vegetable gardens or grow orchards full of exotic fruit. There are herb gardeners and OCD topiary gardeners. There are knot gardeners, and orchid keepers, and pharmacological botanists with climate controlled greenhouses. I am a flower gardener who also enjoys ornamental trees (a combination which makes for a beautiful but not entirely practical garden), however the strangest gardeners of all must be succulent gardeners who tend surreal writhing beds of mutated globes, obscene barrels, and fat tentacles all covered with thorns and spikes!

Succulent plants are desert dwellers which store water in specialized internal storage structures (which, because of the nature of water, are usually thickened and fleshy). In order to fend off the animal inhabitants of deserts (who also live on thirst), these plants have evolved all sorts of defenses to protect their internal cisterns. Thus the cacti, aloes, orpines, agaves, spurges, and so forth are covered with wicked siliceous spikes or with rows of tooth-like spines or with stinging alkaline sap (or in some cases are just straight-up deadly poisonous).

Succulent gardeners revel in this botanical arms race. The best cactus gardens look like the homes of hallucinating sorcerers. Forboding olive towers loom over chartreuse striped tendrils and purple spiky blobs. Snaky limbs bearing obscene fluorescent blooms reach out from a fat orange orange caudex above a world of yellow globes studded with black spines. Just look at these strange landscapes and revel at the combined power of nature’s asceticism and humankind’s sybaritic excess!

The San Diego Botanic Gardens

I have assembled a little gallery of these monstrous and beautiful dry gardens, but none of the images rival the real thing. You should jump in your car and head for a nearby botanical garden (even in cold latitudes there are usually desert greenhouses), or, if you are really feeling disenfranchised just head for Los Angeles where the craziest cactus gardens on Earth are right there on some absentee producer’s front lawn.
