Lophophora williamsii var. San Antonio Cactus Seeds

Lophophora williamsii var. San Antonio is a rare and highly collectible locality form associated with the San Antonio region of Mexico. Locality forms are especially valued by collectors because they represent naturally occurring populations that may exhibit subtle differences in body shape, rib structure, coloration, and growth habit while remaining true to the species.

Like all forms of Lophophora williamsii, the San Antonio variety develops a smooth, spineless, button-shaped cactus with broad, rounded ribs divided into soft tubercles. Its attractive blue-green to gray-green epidermis is often covered with a natural glaucous coating that helps protect the plant from intense desert sunlight while enhancing its distinctive appearance.

As the cactus matures, it develops a low, flattened profile with a dense woolly crown at the center. Mature specimens may gradually produce offsets, eventually forming attractive clusters that become increasingly impressive over many years. Each seed-grown plant displays subtle natural variation in size, rib formation, and coloration, making every specimen unique.

During the growing season, mature plants produce elegant pale pink to light pink flowers that emerge from the woolly crown. After successful pollination, slender pink fruits may develop, each containing numerous tiny black seeds.

Growing Lophophora williamsii var. San Antonio from seed is a rewarding experience for collectors interested in cultivating rare locality forms while observing the slow development of one of the world’s most recognizable desert cacti.
