The ghost plant is one of the most forgiving of all succulents, forming trailing stems of chalky grey rosettes that shift from palest lilac to warm apricot-pink depending on how much sun they receive. It earns its place tumbling over the edge of a pot, a dry stone wall or a gravel bed, where its pearly colouring sets off darker foliage beautifully. Most remarkable of all, a single fallen leaf will happily root itself into bare grit and produce a new plant.
Growing conditions
Give ghost plant the brightest position you can offer. In full sun the rosettes tighten and flush pink, bronze or soft apricot; in shade they stretch, stay blue-grey and lose their compact shape. Under glass, a south- or west-facing windowsill suits it well, though very hot glass in midsummer can scorch unacclimatised leaves.
Drainage matters far more than fertility. Use a gritty compost — roughly half loam-based compost to half horticultural grit, perlite or pumice — and avoid peat-rich mixes that stay sodden. A neutral to slightly alkaline pH of around 6.5 to 7.5 is ideal, and the plant is perfectly content in poor, stony ground.
In mild coastal and urban gardens it can live outdoors all year in a raised bed, wall crevice or green roof, provided winter wet is excluded. Elsewhere, treat it as a container plant to be moved into a cold greenhouse, porch or conservatory before temperatures drop below about 2 °C.
How to plant Graptopetalum
Plant in spring, from April to early June, when light levels are rising and roots establish quickly. Autumn planting is risky outdoors because cold, wet compost around fresh roots almost always leads to rot.
Spacing: allow 30–40 cm between plants so trailing stems can spread without crowding and air can circulate around the rosettes.
Depth: set the stem base just at soil level — never bury the lowest leaves, which will rot where they touch damp compost.
Soil preparation: work in plenty of grit or coarse sand, and on heavy ground plant into a raised bed or mound at least 15 cm high.
Watering in: water once lightly to settle the grit, then leave the plant dry for a fortnight to encourage roots to search downwards.
Propagation: twist off a whole leaf, let the wound callus for three to five days, then lay it on dry gritty compost — roots and a tiny rosette appear within a few weeks.
Care through the seasons
Spring: This is the main growth period and the time flower stems appear, carrying star-shaped white blooms freckled with red. Resume watering gradually, soaking thoroughly then allowing the compost to dry out completely before repeating. A single half-strength feed of low-nitrogen liquid fertiliser in April is ample for the whole season.
Summer: Water every ten to fourteen days in containers, less in open ground, always in the morning and always at the base. Growth often pauses during the hottest spells, which is normal — do not try to force it with extra feed. Move newly bought plants into full sun over two or three weeks to avoid scorching the farina-coated leaves.
Autumn: Taper watering off sharply from late September so the plant enters winter almost dry. Tidy any leggy stems by beheading the rosettes and replanting them — autumn cuttings root slowly but reliably in a frost-free spot. Clear fallen leaves from around the crown, as rotting debris is a common source of infection.
Winter: Ghost plant becomes semi-dormant and needs little or no water between November and February, just enough to stop the roots shrivelling. Keep it bright, airy and above 2 °C, and protect outdoor plants from rain with a pane of glass or an open-sided cloche.
Best varieties to grow
The species itself is the classic choice, but several selections and intergeneric hybrids offer different colouring and habit.
Graptopetalum paraguayense subsp. bernalense — a tighter, greener and more compact form with smaller rosettes, useful in troughs and alpine pans.
Graptopetalum paraguayense ‘Purple Haze’ — looser, more open rosettes that take on distinctly lilac to purple tones in strong light.
×Graptoveria ‘Fred Ives’ — a vigorous cross with Echeveria gibbiflora, bearing large bronze-pink rosettes up to 20 cm across.
×Graptosedum ‘California Sunset’ — a sedum hybrid with narrower leaves that turn glowing orange-coral in full sun and drought.
Pests, diseases and common problems
Root and stem rot: translucent, yellowing or collapsing leaves at the base, usually after overwatering or winter wet. Lift the plant, cut back to clean white tissue, let it callus for a week and restart it as a cutting in dry grit.
Mealybug: white cottony clusters hidden deep between the leaves and around the roots, causing stunted, sticky growth. Dab colonies with a cotton bud soaked in surgical spirit and follow up with a plant-based soap spray every ten days.
Vine weevil: plants wobble loose in the compost whilst creamy C-shaped grubs eat the roots, most often in containers. Drench the compost with parasitic nematodes (Steinernema kraussei) in spring and early autumn when soil is above 5 °C.
