Lophophora williamsii f. variegata
| Light | As for the parent species, but variegated tissue burns easily — bright but filtered light suits it best |
|---|---|
| Water | Sparingly; allow to dry fully between waterings, dry rest in winter |
| Soil | Fast-draining mineral mix (see Soil and potting mix) |
| Temperature | Keep above freezing; USDA zones 10–11 |
| Propagation | Offsets and grafting; seed rarely comes true |
| Toxicity | Contains psychoactive alkaloids; controlled by law (see Legal status) |
Lophophora williamsii f. variegata is a variegated form of the spineless, button-like cactus peyote, in which patches of the body carry reduced or absent chlorophyll. These sectors appear as irregular yellow, pink, or cream blocks against the normal blue-green skin, making the plant a prized ornamental rarity among collectors. It is not a distinct species but a chlorophyll mutation of ordinary Lophophora williamsii, and it carries exactly the same legal restrictions as the parent (see Legal status below).
Description
Like the parent species, this is a low, soft-bodied, spineless cactus with a flattened globular shape, broad rounded ribs and a woolly crown of areoles. What sets the variegated form apart is its colouring: mutation reduces the chlorophyll in parts of the tissue, so the plant develops sectors, bands or flecks of yellow, gold, pink, salmon or cream wherever pigment is missing. The pattern is unstable and unpredictable — it can shift as the plant grows, and the balance between green and variegated tissue varies enormously from plant to plant.
Because the pale sectors cannot photosynthesise, a heavily variegated plant relies on its remaining green tissue to feed the whole body. Plants that lose too much of their green area grow slowly or weaken. Flowering, when it occurs, follows the parent species: small pink blooms from the woolly centre.
Cultivation
Care is broadly as for the parent species — see Lophophora williamsii for the full account — grown in a very free-draining, mostly mineral mix, watered thoroughly only once the soil has dried completely, and kept dry and cool through winter. Overwatering is the usual cause of loss.
The one important difference is light. Variegated tissue has little or no protective pigment, so it scorches far more easily than normal skin. Give bright light to keep the plant compact and to maintain the contrast between green and pale areas, but filter the fiercest afternoon sun to avoid burning the pale sectors. Too little light, on the other hand, encourages soft, etiolated growth and can wash out the variegation.
Weakly variegated or highly prized specimens are sometimes grafted onto a vigorous rootstock. Grafting boosts the plant's overall vigour and can support forms that carry too little green tissue to thrive comfortably on their own roots. See Repotting and Watering for general technique.
Propagation
Variegation of this kind is not reliably passed on through seed, so named variegated plants are usually maintained vegetatively. Lophophora produces offsets (pups), and a pup that inherits variegated tissue can be separated and rooted, or grafted to build up strength. Because the trait is a somatic mutation, results are never guaranteed — offsets may revert to plain green or, occasionally, to fully chlorophyll-free tissue that cannot survive on its own.
Legal status
Lophophora williamsii — including this variegated form — contains psychoactive alkaloids and is a controlled plant in many countries. In the United States it is listed as a Schedule I substance, and simple possession or cultivation is prohibited outside of specifically recognised exemptions. Like the entire cactus family, the genus is also listed under CITES Appendix II, which regulates international trade.
Being a variegated ornamental confers no special exemption: the mutation changes only the plant's appearance, not its legal classification. Growers should check and comply with the laws that apply in their own jurisdiction before acquiring or keeping this plant. This article is horticultural reference only and does not describe, endorse, or explain any use of the plant beyond ornamental cultivation.
