Lophophora williamsii var. Grandiflora Cactus Seeds

Lophophora williamsii var. Grandiflora is a rare and highly sought-after horticultural form prized for its larger-than-average flowers, as reflected in its name, Grandiflora, meaning “large-flowered.” This exceptional variety combines the classic beauty of Lophophora williamsii with impressive floral displays, making it a favorite among collectors and specialty cactus growers.

Like all forms of Lophophora williamsii, the Grandiflora variety develops a smooth, spineless, button-shaped body with broad, rounded ribs divided into soft tubercles. The epidermis typically ranges from soft blue-green to gray-green and often has a subtle glaucous coating that helps protect the plant while enhancing its elegant appearance.

As the plant matures, it develops a compact, flattened growth habit with a dense white woolly crown at its center. Mature specimens may slowly produce offsets, eventually forming attractive clusters. Every seed-grown plant develops slight natural variation in size, rib formation, flower characteristics, and coloration, making each specimen unique.

The defining feature of Lophophora williamsii var. Grandiflora is its showy, larger-than-average pale pink to soft pink flowers, which emerge from the woolly crown during the growing season. Following successful pollination, elongated pink fruits develop, each containing numerous tiny black seeds.

Growing Lophophora williamsii var. Grandiflora from seed offers collectors the opportunity to cultivate a distinctive flowering form while enjoying the slow and rewarding growth of one of the world’s most admired desert cacti.
