Lophophora diffusa var. koehresii ‘San Francisco’ Cactus Seeds

Lophophora diffusa var. koehresii ‘San Francisco’ is a rare collector-selected form associated with the San Francisco locality in Mexico. Highly valued by cactus enthusiasts, this unique selection combines the distinctive characteristics of Lophophora diffusa with a documented collector lineage, making it an exceptional addition to any specialty cactus collection.

Like other members of the Lophophora genus, this variety develops a smooth, spineless, button-shaped body with a compact, symmetrical growth habit. Compared to Lophophora williamsii, Lophophora diffusa typically has broader, less-defined ribs and a softer, pale yellow-green to light green epidermis. Its subtle coloration and rounded form give the plant a refined, sculptural appearance that is highly appreciated by collectors.

As the plant matures, it develops a dense white woolly crown at the growing point. Mature specimens generally remain solitary but may occasionally produce offsets under excellent growing conditions. Seed-grown plants naturally exhibit slight variations in body shape, coloration, and rib formation, making each specimen unique while retaining the defining characteristics of the San Francisco selection.

During the growing season, mature plants produce elegant white to creamy white flowers, sometimes with a faint yellow or pale pink tint depending on the individual plant and growing conditions. Following successful pollination, slender fruits develop, containing numerous tiny black seeds.

Growing Lophophora diffusa var. koehresii ‘San Francisco’ from seed is a rewarding long-term project for collectors seeking an uncommon locality form with exceptional ornamental value and botanical interest.
