Slender wheatgrass: complete guide

Overview

Slender wheatgrass (Elymus violaceus) is an impressive arctic grass originating from East Siberia and North America. This is a very special grass that is extremely suitable for arctic or mountainous conditions.

This grass is one of the most winter-hardy grass species. It grows in areas where other plants struggle. Slender wheatgrass is ideal for gardeners wanting to create an authentic northern or arctic garden.

The grass has an elegant appearance with fine spikes and graceful foliage. Despite its arctic origins, it can also grow in more temperate climates.

Appearance and bloom

Elymus violaceus has fine, thin leaves that grow upright. The leaves have a characteristic purplish or violet color under certain light conditions.

The spikes are elongated and elegant. They grow upright and give the grass a very graceful appearance. Blooming occurs in summer.

The grass reaches a height of approximately 30 to 60 cm. In arctic areas, it grows smaller.

The plant forms slowly expanding groups via underground rhizomes.

Ideal location

Slender wheatgrass grows best in open, sunny locations. At least six hours of direct sunlight per day is ideal. The grass can also grow in partial shade.

This grass is very suitable for mountainous gardens and steep slopes. It can also grow well on poor, rocky soils.

Wind is not a problem for this grass. It actually grows even better in somewhat windy locations.

Soil

Slender wheatgrass grows best in dry to moderately moist, poor soils. The grass prefers no rich, heavily fertilized ground. Light, rocky soils are ideal.

Poorer soils are actually better. The grass grows worse in very fertile ground. The grass easily adapts to lean, poor soil.

The plant loves well-draining soil. A neutral to slightly acidic pH level is ideal.

Watering

Slender wheatgrass is very drought tolerant. Once established, it actually needs no water at all.

Young, new plants need somewhat more water until they become well established. After the first year, watering can be drastically reduced.

Excessive water is harmful to this grass. Waterlogging must be avoided.

Pruning

Carefully remove dead, brown leaves and spikes in early spring.

Damaged spikes can be removed at any time.

Maintenance calendar

Summer: Almost no maintenance needed. Enjoy the blooms.

Autumn: Still beautiful. The spikes remain attractively visible.

Winter: The grass remains winter light green or yellow.

Winter hardiness

Slender wheatgrass is extremely winter hardy. The grass originates from arctic areas and can withstand temperatures of -40 degrees or lower.
