Lophophora williamsii var. Rio Pecos Cactus Seeds

Lophophora williamsii var. Rio Pecos is a highly collectible locality form associated with populations found near the Rio Pecos (Pecos River) region of northern Mexico and the Texas borderlands. Collectors value locality forms because they preserve the characteristics of naturally occurring regional populations, allowing enthusiasts to cultivate plants with documented geographic origins.

Like all forms of Lophophora williamsii, the Rio Pecos variety develops a smooth, spineless, button-shaped body composed of broad, rounded ribs divided into soft tubercles. Its epidermis typically displays attractive shades of blue-green, gray-green, or glaucous green that help reflect sunlight and contribute to its refined appearance.

As the cactus matures, it develops a low, flattened profile with a dense woolly crown at its center. Older specimens may slowly produce offsets, eventually forming attractive multi-headed clusters. Seed-grown plants naturally exhibit slight variations in rib structure, body size, and coloration, making each mature specimen unique.

During the growing season, mature plants produce delicate pale pink to light pink flowers that emerge from the woolly crown. Following successful pollination, elongated pink fruits develop, containing numerous tiny black seeds.

Growing Lophophora williamsii var. Rio Pecos from seed is a rewarding experience for collectors interested in preserving locality forms while cultivating one of North America’s most admired desert cactus species.
