Calendrinia spectabilis, rock purslaneOur Native Plant Spotlight at Evergreen this month is one of our personal, all-time favorites – Calendrinia spectabilis. Calendrinia is a plant genus that was originally named for Jean Louis Calendrini, an 18th-century Swiss Botanist.

Calendrinia, sometimes called Rock Purslane, includes approximately 150 species which bear beautiful colors anywhere from red and purple to white. The Calendrinia are native to North America, Australia, and Chile.

The blooming season for this fabulous, drought tolerant, and truly stunning plant begins in spring and continues well into the fall in our warm California weather. It is easily propagated, groomed, and shared.

Calendrinia spectabilis is the staff favorite of all of us here at Evergreen Nursery. We are all very excited for you to have an opportunity to have at least one of your own- we feel confident that you will enjoy them as we all do.

Calendrinia spectabilis, rock purslaneAppearance

Our Calendrinia spectabilis has a strong magenta-colored flower with a long stem.  The succulent, silver foliage will tolerate nearly any type of situation. It grows to a height of 10-18″ and spreads into a dense groundcover to about 4′ wide.

Soil and Water Requirements

The Calendrinia spectabilis can thrive under the toughest circumstances but does best in loamy or sandy, fast-draining soil. It prefers full sun but can tolerate a bit of shade. Being succulent, it stores moisture for periods of drought, making it perfect for xeriscape gardens.


Calendrinia is not a fussy plant at all and doesn’t require deadheading. It can be cut back to about 6″ in the winter to keep the growth tight and tidy.
