Artemisia scoparia: complete guide

Overview

Artemisia scoparia, commonly known as redstem wormwood or broom mugwort, is a fascinating annual herb from Eurasia. This plant is renowned for its feathery, finely layered foliage and strong aromatic scent. In its natural habitat, it grows over a large geographic area from Europe to Asia.

Redstem wormwood is ideal for gardeners wanting to grow traditional herbs with minimal maintenance.

Appearance and Bloom

Artemisia scoparia grows as an upright annual plant that typically reaches 30-100 cm in height. The stems are reddish, which gives the plant its name. The leaves are very fine, feathery, and finely dissected, giving the plant a very light, feathery appearance.

In summer and fall, very small yellow-green flowers bloom in clusters. These flowers attract beneficial insects.

Ideal Location

Artemisia scoparia requires full sun to half shade. At least 5-6 hours of direct sunlight daily is ideal. It also grows in somewhat shadier locations but is less vigorous.

This plant grows best in warm locations.

Soil

Redstem wormwood grows in almost any soil type but prefers sandy, well-drained soils. A pH of 6.0-7.5 is ideal. It tolerates dry, poor soils well.

Heavy clay or waterlogged soils can hinder growth. Well-drained soils give the best results.

Watering

Artemisia scoparia is highly drought-tolerant once past the seedling stage. Water sparingly. The plant grows better in dry to moderately moist conditions.

Young seedlings need regular watering until well-rooted. Thereafter, minimal water is needed.

Pruning

Minimal pruning needed. Remove only very straggly stems or damaged parts. The plant grows naturally in a neat form.

Maintenance Calendar

Spring: sow directly in the garden after the last frost danger. Summer: water young plants regularly. Fall: harvest seed before they scatter. Winter: no maintenance.

The plant often self-seeds.

Winter Hardiness

Artemisia scoparia is not winter-hardy - it is an annual plant. It does not survive winter in temperate climates. However, in warm regions it can behave as a self-seeding annual.

Started seedlings can potentially be kept indoors.
