Edelweiss

Sun

Full sun; a little afternoon shade can help in warmer gardens, provided the site remains open and airy.

Water

Water moderately while establishing. Once established, allow the soil surface to dry between waterings, but do not leave container plants completely dry for long periods.

Soil

Lean, gritty, sharply drained soil, preferably neutral to alkaline. Avoid rich compost, heavy clay and sites that stay wet in winter.

Height

0.5-1 ft (0.15-0.3 m)

Spread

0.5-1 ft (0.15-0.3 m)

Flowers

Early to late summer; small yellowish flower clusters surrounded by conspicuous, woolly white bracts.

Foliage

Narrow grey-green leaves covered in fine hairs, forming a low clump; usually dies back in cold winters but may retain some leaves in mild conditions.

Slow to moderate

Growth rate

Slow

• Plant with the crown at soil level in a raised rock garden, scree bed or freely draining trough.
• Water new plants during dry spells, directing water onto the soil rather than soaking the crown.
• Avoid routine feeding; rich soil encourages soft growth and fewer characteristic compact flower stems.
• Use a thin gravel mulch around the crown instead of moisture-holding organic mulch.
• Keep fallen leaves away from the crown and shelter containers from prolonged winter rain without enclosing them.

Pruning. Cut spent flower stems back to the basal leaves after flowering, unless you want seed. Remove dead foliage in early spring without cutting into the living crown.

Early spring

Remove dead foliage and check that gravel and soil have not buried the crown.

Spring

Plant into sharply drained soil once the ground is workable; water until established.

Late spring

Check troughs and pots regularly for drying out as growth and flower stems develop.

Summer

Remove faded flower stems, or leave a few to collect seed when the heads turn dry and fluffy.

Autumn

Clear fallen leaves and check that drainage holes and runoff routes remain open.

Winter

Protect pots from persistent rain with an open-sided cover in wet climates; keep them outdoors and ventilated.

• Plant in a sunny rock garden among limestone rocks, where the pale flowers stand above the stones.
• Grow in an alpine trough with small saxifrages and houseleeks for a close-up display.
• Use small groups along the front of a raised gravel bed, away from vigorous neighbours.
• Combine with low blue-flowered alpines for contrast with the silver-white bracts.

Garden styles it suits: Alpine rock garden, Mountain lodge, Dry gravel garden, Small-space and White garden.

Plant it with: Mossy saxifrage, Houseleek, Alpine pink, Carpathian bellflower, Spring gentian and Creeping baby's breath.

Wildlife: The small flower clusters provide pollen and nectar for visiting insects, including flies and small bees.

• Crown or root rot in wet soil: improve drainage, keep the crown exposed and move container plants out of persistent winter rain.
• Decline in hot, humid summers: choose an airy site with cooler afternoon conditions; in persistently hot climates, this may not be a reliable perennial.
• Slugs and snails eating young growth: inspect new shoots and use hand-picking or an appropriate labelled control.
• Loose growth and poor flowering in rich soil or shade: move to a sunnier position and stop feeding.

Not known to be toxic to people, cats, dogs or horses. No part is recognised as a significant poisoning hazard, but animal-specific safety information is limited; it is an ornamental plant, not a food crop.

• Pearly everlasting (Anaphalis margaritacea)

  Much taller, with branching stems carrying many small, papery white flower heads rather than the low, woolly star-shaped clusters of edelweiss.

• Mountain everlasting (Antennaria dioica)

  Forms spreading mats of spoon-shaped basal leaves and bears small white or pink flower heads without edelweiss's broad, star-like woolly bracts.

Edelweiss comes from German words meaning 'noble white', while Leontopodium means 'lion's little foot', referring to the woolly flower heads.

Propagation. Sow seed on the surface of a gritty seed compost and keep cool, bright and lightly moist; do not bury it deeply. Divide healthy, established clumps carefully in spring, keeping roots attached to each section.

Accepted botanical name
