    Landscaping With Cactus

    Cactus and succulents are enjoying an overwhelming popularity in the garden design world and even beyond, as their exotic and iconic images appear in pop culture and their fruits and pads are even being made into cocktails, salads and even jellies.

    Beginning and experienced gardeners start out with a few tiny cactus or succulents in containers, just for the novelty. Something hooks them—maybe the intrigue of the plants' low maintenance or their amazing forms and patterns. If you live in a cactus-friendly region, which is much of western North America, Central America, and South America, it's hard not to notice that these hardy plants can be incorporated into a landscape. 

    If you or a landscaping pro have experience and/or knowledge of these desert natives, cactus and succulents can be easily integrated with other drought-tolerant trees, shrubs, perennials, and ornamental grasses for a beautiful and natural looking garden design. Working with cactus requires some research and understanding of their sunlight, soil and watering needs. The specimens with spines need to be handled carefully without getting stuck.

    What's the Difference Between Cactus and Succulents?

    Remember this: all cactus plants are succulents, but not all succulent plants are cactus. Repeat that a few times for it to really sink in. A succulent comes from several botanical families and is defined or classified by its moisture-storing capacity. 

    Cactus (or cacti) can be identified by their small, round areoles from which spines (thorns), branches, leaves, hair, and flowers grow. While some succulents do a good job of impersonating cactus, if they are lacking the round, cushion-like areoles, then you can tell they are not cactus.

    Another distinction: succulents are native to most parts of the world, but cacti are only indigenous from Alaska to Chile in the Western Hemisphere. 

    Cactus for Gardens and Containers

    We've researched and identified some of the most attractive and popular cacti that you can work within a landscape design, whether it's a few containers, raised planting beds, or an entire yard. Consult nurseries and horticulture or cactus societies in your area for additional growing tips that apply to your particular region. 

    Cactus are presented in alphabetical order by their common names.

    Botanical Name: Carnegiea gigantea

    Other Names: Sahuaro, giant cactus, sage of the desert

    Size: A slow grower that may take more than 100 years to reach its full, treelike height of 30 to 52 feet (9 to 15.6 meters)

    Flowers: Fragrant, greenish-white flowers bloom at night in late spring/early summer

    Design Ideas: If planted near desert trees like mesquite and palo verde, saguaros will be protected from heat and frost. In a landscape, they are attractive when grouped with golden barrels, prickly pears, and drought tolerant shrubs like chuparosa and Baja fairy duster.

    These columnar plants are usually found in Sonora, Mexico, the central/southern Arizona desert, and parts of California. Tall and branching, it is one of the most iconic cacti in the world. Unfortunately, they are one of the least cold-tolerant cacti. Carnegiea are named after American industrialist and philanthropist Andrew Carnegie.

    Turk's Cap Cactus

    Botanical Name: Melocactus matanzanus 

    Size: Up to 3.5 inches (9 centimeters) tall and to 3.5 inches in diameter.

    Flowers: Bright pink flowers with fur, which likes to be misted with a water bottle a few times per week

    Design Ideas: For a cactus, Turk's cap is slightly more high maintenance than most and should not be allowed to dry out. Since it grows on rocky hillsides in its native habitat, it will grow well both on slopes and in rock gardens, as well as xeriscapes with native shrubs, perennials, and wildflowers.

    Explorer Christopher Columbus reportedly discovered Melocactus on a West Indies island and brought home it and other cacti to Europe.

    Size: To 6 feet (1.8 meters) high and up to 4 feet (1.2 meters) wide

    Flowers: Blooms are yellowish-green
