Alpine dock: complete guide

Overview

Alpine dock (Rumex alpinus), also known as monk's rhubarb or mountain dock, is a robust perennial plant in the Polygonaceae family. The plant grows naturally in the mountains of Central and South Europe to West Iran, at elevations of 1,500 to 3,000 meters.

Alpine dock is an impressive plant with large, glossy leaves. The plant is widely used in traditional medicine and nutrition. The stems can be eaten and have a sour taste. It is also widely eaten by livestock on mountain meadows.

Appearance and Bloom

Alpine dock is a large plant reaching 80 to 150 centimeters tall. The leaves are very large, up to 40 centimeters long, triangular and shiny green. They are heart-shaped at the base and have veining. Young leaves have a reddish tint.

Flowers appear from July to September. They grow in long, densely packed racemes at the top of thick, strong stems. The flowers are green and inconspicuous.

The fruits are leaf-like and have distinct angles and veins.

Ideal Location

Alpine dock thrives best in locations with full sun to partial shade. The plant can tolerate up to seven hours of direct sunlight daily. On mountain locations, where air circulation is good, the plant grows best.

The plant grows well in mountain gardens, alpine troughs, and rock gardens.

Soil

Alpine dock prefers rich, fertile soil. The pH should range from 7.0 to 7.5, so slightly basic to neutral. The plant accepts well-draining soils.

When planting, add plenty of compost or organic matter. This provides the plant with necessary nutrients.

Watering

Alpine dock loves consistently moist soil. Water regularly, especially during dry periods. The plant grows in mountain environments where mountain springs are nearby.

In gardens, water regularly, especially during the growing season.

Pruning

Pruning is minimally needed. Remove spent flower heads after flowering ends. This can prevent self-seeding. Old leaves can be removed.

Maintenance Calendar

Spring: Plant young plants in spring. Add fertilizer. Water regularly.

Summer: Water regularly. Flowers appear. Remove spent flowers.

Fall: Seed ripens. Reduce watering. Protect from frost in mild climates.

Winter: In cold climates, the plant dies back. Protect roots with mulch. In mountain climates it is natural and the plant can withstand snow.

Winter Hardiness

Alpine dock is very hardy and thrives in zones 5-9 (down to -29 degrees Celsius). The plant survives freezing in mountain environments. In milder climates, it can remain green year-round.

Companion Plants

Alpine dock grows well with other alpine plants and mountain herbs. It attracts bees.
