Lophophora williamsii Texana is a specific variety of the Lophophora williamsii cactus, recognized for its distinct characteristics and native range. This plant thrives in arid environments. This guide provides insights into identifying, growing, propagating, and understanding the conservation and legal aspects of this cactus.
Identifying Lophophora williamsii Texana
Lophophora williamsii Texana exhibits a spineless, globular form, ranging from blue-green to grayish-green. Its structure often features fewer, more pronounced ribs than other varieties. The plant usually grows as a single head, though older specimens (around 3-4 years old or 5-6 centimeters in diameter) may develop offsets or “pups” at their base.
This cactus produces pinkish-white to pale pink flowers from its fuzzy, woolly center during its growing season. Seed pods can sprout within two weeks after flowering. In its natural habitat, Lophophora williamsii Texana is found in Texas and northern Mexico, inhabiting arid, rocky terrains, often in areas with decomposed limestone.
Cultivating Lophophora williamsii Texana
Light Requirements
Lophophora williamsii Texana requires bright, indirect light or filtered sun for optimal growth. While it tolerates some direct morning sunlight, prolonged exposure to harsh sun can cause scorching. Indoors, place the plant near a south-facing window with sheer curtains or use grow lights for 10-14 hours daily. Gradual acclimatization is recommended when changing lighting conditions.
Soil Composition
A well-draining, gritty, and mineral-rich soil mix is vital for Lophophora williamsii Texana. This cactus is prone to root rot if moisture lingers. A suitable potting mix should contain a high proportion of inorganic materials like pumice, perlite, and coarse gravel, with minimal organic matter. Crushed activated charcoal and seashells or bird grit can also be incorporated for drainage and minerals.
Watering Practices
Infrequent but thorough watering is key for Lophophora williamsii Texana, following a “soak and dry” method. The soil must dry completely between waterings to prevent rot. During the active growing season (warmer months), water every few weeks. During winter dormancy, reduce or cease watering, especially if temperatures drop below 40°F (4°C), as watering in cold can be fatal.
Temperature and Humidity
Lophophora williamsii Texana thrives in warm temperatures and low humidity, mimicking its desert environment. It tolerates heat, with optimal growth often above 100°F (38°C) during the growing season. While resilient to heat, it is vulnerable to frost; prolonged freezing temperatures can be damaging. Good air circulation helps prevent fungal issues from high humidity.
Fertilization
Minimal fertilization is sufficient for Lophophora williamsii Texana. If needed, use a low-nitrogen, high-potassium fertilizer diluted to a weak solution. Apply sparingly during the active growing season, about once a month. Over-fertilization can harm the plant.
Pest and Disease Management
The most common issue is root rot, caused by overwatering or poor drainage. Ensure the soil dries completely between waterings and use a porous soil mix. Pests include mealybugs and spider mites, identified by cottony masses or fine webbing. Treat by carefully removing pests with rubbing alcohol on a cotton swab or using an appropriate horticultural insecticide.
Propagating Lophophora williamsii Texana
Seed Propagation
Propagating Lophophora williamsii Texana from seed is common but slow. Sow seeds in a well-draining cactus mix, keeping the substrate lightly moist until germination. This requires consistent temperatures (70-100°F / 21-38°C) and bright, indirect light. Seedlings grow very slowly, taking several years to reach significant size.
Offset Propagation
Lophophora williamsii Texana can also be propagated from offsets (“pups”) that form at the base of the main plant. Carefully remove an offset with a clean, sharp knife. Allow the offset to “callus” (dry out for several days to a week) to form a protective scab. Once callused, plant it in a well-draining medium and water sparingly until roots establish.
Conservation and Legal Considerations
Lophophora williamsii, including the Texana variety, is listed on Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). This means the species is threatened with extinction, prohibiting international commercial trade in wild-collected specimens. Trade in cultivated specimens is highly restricted, requiring specific permits and adherence to regulations. Its endangered status is due to habitat destruction, root plowing, and over-collection.
In the United States, Lophophora williamsii contains mescaline, a Schedule I controlled substance under federal law (21 U.S.C. § 812). This classification generally makes its cultivation, possession, and distribution illegal for the general public. Schedule I substances have a high potential for abuse and no accepted medical use in the U.S.
An exemption exists under the American Indian Religious Freedom Act of 1978 (amended 1994). This allows members of the Native American Church to use Lophophora williamsii for bona fide religious ceremonies. This narrow legal provision applies only to authorized religious use by Native American Church members and does not extend to the general public. Individuals cultivating this plant are responsible for complying with all applicable federal, state, and local laws, as regulations vary.
