Species Rock Wormwood

Rock Wormwood

Artemisia woodii

Rock Wormwood (Artemisia woodii) is a low-growing, mat forming perennial shrub native to western North America. It is green-gray in colour and grows up to 2 inches tall. It forms dense, spreading clusters of narrow, needle-like leaves with tiny white flowers. The plant produces a large number of seeds that can remain dormant for many years, leading to regrowth even in adverse conditions. It is tolerant of drought, poor soil, and burial under debris, but prefers a well-drained site high in calcium and low in nitrogen. Rocks Wormwood can be used in rock garden beds, for erosion control, as a low-growing ground cover, or as an attractive border.

watering

When it comes to watering rock wormwood, a key element to remember is to provide only adequate watering. To properly water your rock wormwood plants, the soil should be allowed to dry out almost completely between waterings. When the surface of the soil feels dry, slowly give your plant just enough water until moisture is seen dripping out of the drainage holes; then stop. During peak growth season, water your plants every 7 to 10 days. In the winter, allow the soil to dry out completely before adding water.

sunlight

Rock Wormwood (Artemisia woodii) grows best in full sun. It prefers 8-10 hours of direct sunlight each day, and should be planted in an area that receives at least 5 hours of sun in the morning and 3-4 hours in the afternoon. Rock Wormwood should never be in an area that is too shady as it can reduce blooming and promote the growth of too much foliage. When planting, make sure to choose a sunny spot with well-drained soil so the plant’s roots can get the nutrients they need.

pruning

Rock Wormwood should be lightly pruned in late Winter or early Spring. It is important to note that pruning may increase the density of the plant, so only light pruning should be done, removing only the oldest, tallest, or broken shoots. This should be done just before new shoots and flowers appear. Additionally, some control pruning can be done in Summer in order to contain the size and shape of the plant. Extremely vigorous stems should be removed and can be cut back to a monofoliate branch or a few new leaves. Be sure to follow all the usual safety guidelines when pruning this plant.
