Arrosage: Allow the soil to dry out significantly between waterings to prevent root rot.
Engrais: Apply a light, balanced fertilizer sparingly during the spring growing season.
Taille: Trim back dead foliage in late winter or early spring to encourage fresh growth.
Rempotage: Repot only when the plant becomes root bound, using a very gritty alpine soil mix.
Sol: Rocky, sandy, well draining
pH du sol: Neutral to slightly alkaline
Température: -25 à 25°C
Humidité: 30 à 50%
Résistance à la sécheresse: Élevée

Problèmes courants

Root rot — Occurs when the soil stays too wet or lacks proper drainage.
Aphids — Small insects that may cluster on new growth during the spring.

La cultiver

Multiplication: seed, division
Quand planter: spring, autumn
Hivernage: Ensure the plant is kept dry during winter to prevent crown rot. A layer of grit around the base helps keep the foliage off damp soil.
En pot: It is excellent for containers, provided you use a very gritty, fast-draining alpine soil mix in a pot at least 15 cm wide.

Seed

1. Sow seeds on the surface of a gritty, moist seed mix in early spring.
2. Keep in a cool, bright location.
3. Germination can be slow and erratic.

Division

1. Carefully lift the plant in early spring.
2. Gently tease the root clump apart.
3. Replant immediately into well-draining soil.

Pair with other slow-growing alpine plants to prevent them from being crowded out.

Bonnes associations

Aster alpinus — They share similar requirements for rocky, well-drained soil.
Phlox subulata — This provides a nice color contrast and thrives in similar alpine conditions.

Espèces similaires

Artemisia ludoviciana — It offers similar silver foliage but is much more vigorous.
