Unfortunately, as with most cacti, Ferocactus is a slow growing plant, taking several years to reach 10 cm in height. Because of its rarity and beauty, this cactus has commercial potential as an ornamental plant. It makes a great specimen for the dry coastal garden in the southern counties. Unfortunately, there are no reports on the climatic conditions required for Ferocactus seed germination in the field. Although wild populations are in the immediate vicinity of the coast, it can be grown inland in areas that do not experience regular freezing. The cactus blooms in yellow to greenish flowers with red or pink scales. The spines stick straight out or may curve a bit, and are red when new, dulling to gray or tan. The flesh is bright green and arranged into several ribs covered in arrays of long spines. This cactus is spherical, oblate, or nearly cylindrical, is usually wider than tall, and less than 30 centimeters in height. As a result, it is included on CNPS List 2B.1. Most of its native range is in San Diego County, California, where most of its habitat has already been removed, and much of the remaining habitat is threatened by development, agriculture, and other alterations in its habitat. It is native to southern California and northern Baja California, along a very restricted portion of the coast. PLANTS Profile - Ferocactus sp.About San Diego Barrelcactus (Ferocactus viridescens) 14 Nurseries Carry This Plantįerocactus viridescens is a rare species of barrel cactus known by several common names, including coast barrel cactus and San Diego barrel cactus.Please, enjoy the beauty of their flowers, marvel at the great lengths taken in protection against herbivory and the hot sun under which they live, and do not remove them from the wild. The tunas may be eaten and some Native Americans used this plant for candy.įerocactus plants are rare and most species are afforded protection from their spines. From the spines, fishing hooks can be made. The flowers of the plant were collected and eaten dry or fresh, and the tiny black seeds were ground and eaten as well. They are fairly well known as an emergency source of water in the desert, although experimentation will discourage this practice. The larger spines keep away thirsty desert creatures, and the smaller spines help prevent water loss and scorching by reflecting away some of the intense desert sunlight.Īlmost unbelievably, people use these plants. They are covered with large and small spines. The plants themselves are like thick tubes, with ridges going down the sides. The anthers from the many stamens form a little carpet, from the centre of which come a few styles of the pistil. Between the petals and the numerous stamens is a ring of hairs. The petals of each flower are many, and unlike the flowers of other cacti, do not really form a tube. The flowers appear in a ring near the top of the tube. Ferocactus wislizeni has reddish-orange petals. The most common species in California, Ferocactus cylindraceus, has yellow petals that are reddish at the base. As one would expect of such an iconic emblem of the desert southwest, these plants grow mainly in the desert, in sandy or rocky soils with little water and lots of sun.Ĭactus plants without fail yield beautiful flowers. The Spanish name for this plant is viznaga, a common term for fat, cylindrical cacti, which can also include Mammillaria, Escobaria, and other genera. The genus name Ferocactus is Latin for “fierce cactus,” an apt description that will be affirmed by any who have seen the densely packed, stiff spines covering the fleshy-looking plant. Barrel cacti grow into a squat tubular shape, giving it the appearance of a very spiky ribbed barrel. The Barrel Cactus is a member of the Cactaceae, or cactus family.
