The epiphyllums that I’ve discussed in previous articles may be the most impressive bloomers of the Cactaceae family; but not the only ones. Many other species of cacti also produce elaborate flowers in a wide range of brilliant colors. However, most cacti are grown for their showy stem structures. Many are short and wide, like the golden barrel cactus which is often wider than tall. Others, like the saguaro, grow very tall and lean with multiple branches. Stems of the prickly pear type cacti are broad and flattened. Variations of stem structure are seemingly limitless.

Many other succulent plant species, such as jade tree, are often identified with cacti. The family Cactaceae exhibits swollen green stems which perform photosynthesis and store moisture. Spines are  actually modifies leaves which do not photosynthesize. Most succulents exhibit fleshy, green leaves which photosynthesize with stems which do not. (Most euphorbs behave like cacti with fleshy green stems and spines.) All cacti are endemic to the Americas; but succulents are endemic to every continent except Antarctica.

One need not be a cacti and succulent enthusiast to enjoy them. Many garden enthusiasts use cacti and succulents where the environment is too harsh for more foliar species. Some also enjoy the bold characteristics of cacti and succulents and use them as a “garden sculpture substitute”.

The annual Cacti and Succulent Show and Sale presented by the Northern California Cacti and Succulent Association is an event that would be of interest to garden enthusiasts who would like to become better acquainted with cacti and succulents. The show features hundreds of rare and exotic cacti and succulents. Several thousand plants will be available for sale from more than thirty vendors. Several free seminars feature topics such as potting techniques, propagation, soil composition and showing plants. Experienced members of the Society will be available to answer questions.
