Pachyphytum bracteosum
| Light | Bright light to a little direct sun; ample light keeps the rosettes tight and the farina heavy |
|---|---|
| Water | Deep soak, then allow to dry fully; reduce sharply in winter |
| Soil | Fast-draining, mostly mineral mix (see Soil and potting mix) |
| Temperature | Keep above freezing; happiest in USDA zones 9b–11 |
| Propagation | Leaf cuttings, stem cuttings and offsets (see Propagation — cuttings) |
| Toxicity | Generally regarded as non-toxic to cats and dogs |
Pachyphytum bracteosum is a shrubby Mexican succulent grown for its broad, spoon-shaped leaves of pale silvery-lavender, held in loose rosettes atop thick, gradually lengthening stems. The whole plant is coated in a fine, powdery white bloom (farina), which softens the leaf colour to a chalky pastel and gives the species much of its charm. It belongs to the genus Pachyphytum, a small group of thick-leaved relatives of Echeveria from the Crassulaceae.
Description
Pachyphytum bracteosum forms open, few-leaved rosettes of flattened, obovate (spoon-shaped) leaves. The leaves are notably broad and fleshy, rounded at the tip, and range from grey-green to a distinctly lavender or lilac cast depending on light and season. A dense farinose coating covers the surface — best left undisturbed, as the powder does not regrow once rubbed away and protects the leaf from strong sun.
Unlike the tighter, more symmetrical rosettes of many Echeveria, this species tends to sprawl and build up woody stems over time, with older rosettes lifting on thickening trunks and offsetting from the base. In late spring and summer it can push tall, arching flower stalks bearing conspicuous leafy bracts (the source of the epithet bracteosum) and nodding, bell-shaped flowers in shades of red, largely enclosed by the silvery bracts.
Distribution and habitat
The species is native to Mexico, where it grows on rocky slopes and cliff faces in seasonally dry country. In habitat it roots in gritty, sharply drained ground and endures long dry spells, storing water in its plump leaves and stems — a background worth keeping in mind when deciding how often to water in cultivation.
Cultivation
Pachyphytum bracteosum is an easygoing, beginner-friendly succulent that asks mainly for strong light and a free-draining home. Grow it in a very open, mostly mineral mix and give it the brightest spot you can, with at least some gentle direct sun; in weak light the rosettes stretch, the leaves space out and spread, and the lovely lavender colour fades toward plain green (see Etiolation).
Water by soaking the soil thoroughly, then leaving it until it has dried right out — the thick leaves mean the plant tolerates drought far better than a soggy pot. Cut watering back hard over winter, when growth is naturally slow, to avoid rot in cold, damp conditions. Keep the plant frost-free; it is not hardy. Try to handle it by the stem or pot rather than the leaves, since fingerprints permanently mark the powdery bloom. See Watering and Repotting for general technique.
Propagation
This is one of the simpler succulents to multiply, and several methods work well:
- Leaf cuttings — a clean, whole leaf twisted gently from the stem will often callus and produce a tiny plantlet and roots at its base.
- Stem cuttings — behead a leggy rosette, let the cut end callus for a few days, then set it on dry mix to root.
- Offsets — established plants pup from the base and lower stem; these can be separated once rooted.
Allow all cut surfaces to dry before potting, and go easy on water until roots establish. See Propagation — cuttings, Propagation — leaf and Propagation — offsets for details.
Common problems
- Etiolation — the most common complaint; too little light stretches the stems, flattens the rosettes and washes out the lavender colour.
- Rot — from overwatering or a poorly draining mix, especially in cold weather; leaves and stems go soft and translucent.
- Lost bloom — the farina rubs off with handling and does not return, leaving shiny patches; harmless but cosmetic.
- Pests — mealybugs are the usual pest, tucking into leaf axils and around the roots; watch also for aphids on flower stalks. See Pests and diseases.
