Lophophora williamsii 'Huizache'
Lophophora williamsii 'Huizache is a locality-provenance form of peyote originating from the Huizache area of San Luis Potosí, in the arid highlands of north-central Mexico. It is one of the classic "locality" selections that circulate in the specialist seed trade, prized by collectors for the way plants from a single wild population share a recognisable look. As a provenance form rather than a bred cultivar, its care follows the parent species, Lophophora williamsii, to which growers should refer for the full picture.
Because it is simply peyote of a particular origin, 'Huizache' carries exactly the same legal restrictions as the species — see the Legal status section below.
Description
'Huizache' is not a distinct cultivar in the horticultural sense but a provenance or locality form: seed collected from (or descended from) plants growing near Huizache, San Luis Potosí, and kept as a labelled line so that its origin is preserved. In cultivation such plants show the general characters of peyote — a soft, spineless, blue- to grey-green button with low, rounded ribs, tufts of areolar wool, and small pink flowers from the crown.
Locality lines like this one are valued mainly for consistency and pedigree rather than for any single dramatic trait. The natural variation within any wild population means individuals still differ, so no single fixed form should be expected from the line. As with all peyote, appearance is strongly shaped by growing conditions, age and whether a plant is on its own roots or grafted.
Cultivation
Cultivation is as for the parent species; see Lophophora williamsii for the complete account. In short, peyote wants a very free-draining, mostly mineral mix, bright light, and cautious watering with a full dry-out between drinks and a dry, cool winter rest. Overwatering and heavy, water-retentive soil are the usual causes of loss.
Peyote is naturally slow on its own roots, so some growers speed young plants along by grafting them onto a vigorous rootstock, later rooting the growth down. When keeping a labelled locality line such as 'Huizache', it is worth propagating it in a way that preserves the provenance — ideally by seed from known Huizache parents, or vegetatively — and keeping the label with the plant so its origin is not lost. See Repotting and Propagation — offsets for general technique.

Legal status
As a form of Lophophora williamsii, 'Huizache' is subject to exactly the same controls as the species. Peyote contains mescaline, and in the United States both the plant and mescaline are listed as Schedule I controlled substances under federal law; a long-standing, narrow exemption exists for the sacramental use of peyote by the Native American Church. Legal status varies elsewhere, so growers should check their own national and local regulations before acquiring or keeping plants.
Like the rest of the cactus family, Lophophora is also listed under CITES Appendix II, which regulates international trade. Wild peyote populations, including those in San Luis Potosí, have declined through over-collection and habitat loss, which is part of why nursery-propagated, provenance-labelled seed and plants are valued by conservation-minded collectors.
