Lophophora fricii Haberm.
Lophophora fricii is a globular, spineless cactus with large taproot. The stem is pale grey-green to yellow-green, usually lacking well defined ribs and furrows. The flowers are pale to dark pink and up to 1.6 inches (4 cm) in diameter.
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Lophophora is more tolerant of soil types than its relatives, and typically grows in areas which have decomposed limestone present in the soil. In cultivation, Lophophora does best in a fast draining mineral based soil which is about 2/3 sand.
Abundant water is beneficial in the summer months when the temperatures are over 90 °F (32 °C) and exposed to full sunlight for maximum growth, but must be allowed to dry out completely between waterings.
They should also be fertilized twice a year. Over fertilizing will typically result in the Lophophora developing cracks and splitting.
At times, some Lophophoras will develop a corky material on the plant body if exposed to pesticides or insecticidal soap. This corky condition will usually heal in a manner very similar to human skin if the plants are exposed to full sunlight.
Lophophoras are free flowering in cultivation and although they can withstand low temperatures during winter they do not require a cold shocking in order to initiate flowering.
