Mexican snowball

Sun

Full sun to light shade; provide afternoon shade in very hot climates. Introduce indoor-grown plants to direct sun gradually.

Water

Water thoroughly, then let the potting mix dry before watering again. Keep almost dry in cool winter conditions; never leave the pot standing in water.

Soil

Very freely draining, gritty soil or cactus potting mix amended with pumice or coarse grit. Avoid heavy clay and sites that stay wet in winter.

Height

0.3-0.7 ft (0.1-0.2 m), with flower stems reaching about 1 ft (0.3 m)

Spread

0.7-1 ft (0.2-0.3 m), gradually wider as offsets form

Flowers

Late winter to spring, sometimes into early summer; pink to coral bells with yellow tips on arching stems.

Foliage

Evergreen. Fleshy, spoon-shaped, pale blue-green leaves arranged in tight rosettes, with a powdery white coating and sometimes pink-flushed edges.

Growth

Slow to moderate

Care needed

Low

• Use a pot with drainage holes and empty any saucer after watering.
• Water the soil rather than the rosette, allowing the mix to dry between soakings.
• Feed lightly once or twice during spring and summer with a diluted cactus fertiliser.
• Keep gravel around outdoor rosettes to reduce contact with damp soil.
• Move containers into a bright, frost-free place before cold weather and persistent winter rain.
• Avoid rubbing the leaves; their protective powdery coating does not readily recover.

Pruning. Cut spent flower stems near their base after flowering. Gently remove completely dry lower leaves and detach unwanted offsets in spring or early summer; do not trim healthy leaf tips.

Early spring

Check for mealybugs and remove dry leaves that shelter pests.

Spring

Repot crowded plants into a slightly larger pot with fresh, gritty mix; separate offsets if wanted.

Late spring

After frost risk has passed, gradually acclimatise overwintered plants to outdoor sun.

Summer

Water when the mix has dried and provide afternoon shade if leaves begin to scorch.

Autumn

Reduce watering as growth slows and move pots under bright, frost-free cover where winters are cold or wet.

Winter

Keep sheltered plants in strong light and water sparingly, only when the mix is dry and leaves begin to lose firmness.

• Group rosettes in shallow, well-drained bowls where their pale colour and repeated shapes are easy to see.
• Edge frost-free gravel beds with low clusters beside small aloes and other dry-growing succulents.
• Tuck plants into sunny rock-garden pockets that shed water quickly.
• Use pale gravel and dark containers to emphasise the blue-white foliage in a small courtyard.

Garden styles it suits: Contemporary minimal, Modern courtyard, Modern Mediterranean, Dry gravel garden, Desert / xeriscape and Small-space.

Plant it with: Zebra haworthia, Lace aloe, Blue chalksticks, Jelly bean plant and Ghost plant.

Wildlife: Flowers can provide nectar for visiting insects and, where present, hummingbirds. Its wildlife value is modest compared with locally native flowering plants.

• Root or crown rot: improve drainage, stop watering until the mix dries, and remove rotten tissue; salvage healthy offsets if the main rosette is lost.
• Mealybugs: isolate affected pots, remove visible insects with an alcohol-dampened cotton swab without wetting the foliage broadly, and inspect leaf bases and roots repeatedly.
• Stretched, loose growth: move the plant gradually into brighter light; existing elongated growth will not become compact again.
• Sunburn or frost damage: acclimatise plants gradually to strong sun and keep them frost-free; damaged leaf tissue will not recover.

Not known to be toxic to cats, dogs, horses or people; no part is recognised as poisonous. It is not a food plant, and eating plant material may still cause mild stomach upset.

• Blue rose echeveria (Echeveria × imbricata)

  Usually forms larger, flatter rosettes with broader, more distinctly pointed leaves; Mexican snowball generally has smaller, more cupped rosettes with rounded, spoon-shaped leaves.

• Ghost plant (Graptopetalum paraguayense)

  Has more angular, pointed leaves and eventually develops trailing stems; its flowers are open, white stars rather than pink-and-yellow bells.

• Common houseleek (Sempervivum tectorum)

  Has firmer, sharply pointed leaves, often with fine hairs along the edges, and star-shaped flowers. It is much more cold-hardy, and each flowering rosette dies after blooming.

Echeveria honours Mexican botanical artist Atanasio Echeverría y Godoy, while elegans means elegant; Mexican snowball refers to the pale, rounded rosettes and Mexican origin.

Propagation. Detach offsets in spring or early summer, let cut surfaces dry and callus for a few days, then place them in gritty potting mix. Whole, undamaged leaves can also produce plantlets; keep them in bright indirect light and avoid wet conditions while roots develop.
