Pyrenean scurvygrass: complete guide

Overview

Cochlearia pyrenaica, commonly known as pyrenean scurvygrass or alpine scurvy-grass, is a compact alpine plant from the Brassicaceae family. This plant naturally occurs in European mountains, particularly the Pyrenees, Alps, and other mountain ranges. Pyrenean scurvygrass is perfect for rock gardens and alpine borders and forms a valuable accent in rocky environments. This alpine plant is a true classic for alpine garden enthusiasts.

Appearance and Bloom

Pyrenean scurvygrass forms compact rosettes of heart-shaped, glossy green leaves with attractive shine. The plant typically reaches 5-15 cm in height and forms dense cushions. In spring and early summer (March to July), small, snow-white flowers appear in clusters, each with four petals. The flowers have a characteristic shape typical of the Brassicaceae family and are pristine white in color.

The plant grows tightly together, forming attractive cushions on rock outcrops. The glossy leaves form an attractive green foundation year-round.

Ideal Location

Pyrenean scurvygrass grows best in full sun to partial shade. The plant can grow in full shade but will not flower as profusely. Plant it on rocks, steep slopes, or in rock gardens where drainage is excellent. This is very important for success.

This alpine plant fits perfectly in stone gardens, between rocks, and on walls. It can also grow in containers, provided well-draining potting mix is used. Use alpine potting mixes with generous gravel additions.

Soil

Pyrenean scurvygrass requires well-draining, calcareous soil. The plant naturally grows in stony, rocky environments with preferences for alpine soil. Heavy clay or wet soil causes immediate root rot. In the garden, potting mixes with generous additions of gravel or stones can be used, preferably 50% gravel, 30% stone and 20% potting soil.

A neutral to slightly alkaline soil (pH 7-7.5) is ideal. Drainage is absolutely critical for success.

Watering

Pyrenean scurvygrass is drought-tolerant once established and requires minimal watering. Young plants need regular water until established. Mature plants can survive long without supplementary water.

Preventing wetness is crucial. In wet conditions, the plant grows poorly and root rot may develop. Ensure good drainage by regularly checking if water pools around roots.

Pruning

Pyrenean scurvygrass requires very minimal pruning and practically no maintenance. You can remove spent flowers after blooming to prevent seed set. Remove dead leaves in spring to keep the plant neat.

The plant produces very few seeds, so non-invasiveness is not a concern.

Maintenance Calendar

March-April: Flowering period, check drainage carefully May-June: Continued blooming, minimal water if needed July-August: Seed formation, reduce watering September-February: Winter rest, minimal care, plant remains green

Winter Hardiness

Cochlearia pyrenaica is extremely hardy to -20 degrees Celsius or even colder. The plant originates from high mountains where severe winters are normal. Protection is rarely needed in temperate climates.

Companion Plants

Pyrenean scurvygrass forms beautiful combinations with other alpine plants. Combine with saxifrages, sedums, alpine phlox, and other alpine garden classics. The white flowers provide nice contrast with dark gray or bronze foliage. Plant also with other Brassicaceae plants.

The plant attracts butterflies and other pollinators in spring.

Cochlearia pyrenaica is a must-have for any rock or alpine garden. The compact growth, extreme hardiness, and white flowers make it collection-worthy.
