Pacific Wormwood

Artemisia campestris subsp. pacifica

Pacific Wormwood (Artemisia campestris subsp. pacifica) is a perennial shrub native to the Pacific Northwest. Growing up to 1.5 m tall, its gray-green foliage forms low mounds of woolly-textured growth. Its deep-rooted fibrous system helps prevent soil erosion--making it an ideal choice for naturalization projects. Its clusters of inconspicuous flowers produce small, tan seed heads that are attractive to birds. Enjoy a bit of wild beauty in your garden with Pacific Wormwood!

watering

Pacific Wormwood should be watered deeply but infrequently throughout the growing season. During the dry summer months, it should be watered every 7-14 days and in the spring/fall months, every 14-21 days. It's important to use approximately 1-2 inches of water for each watering. If the soil in the pot becomes dry, increase the amount of water, but be careful not to overwater the soil, as the roots may rot if there is too much water.

sunlight

Pacific Wormwood plants enjoy full sun exposure of at least 8 to 10 hours of direct sunlight per day to grow and thrive. During the summer months, Pacific Wormwood should receive sunlight all day long; however, it can still do well in partial shade when the sun is intense. During the winter, Pacific Wormwood require 6 hours of sunlight per day. These plants prefer the sun to be at its highest point in the sky for the maximum amount of sunlight, so aim to position them in outdoor areas of the home that receive direct sunlight in the afternoon, such as southern-facing windows or open patios.

pruning

Pacific Wormwood should be pruned at the end of winter or the beginning of spring. Prune the plant back to around 4-6 inches in height. Make sure to remove dead wood, diseased leaves, or weak branches. Prune any canes or crossed branches that crowded the center or sides of the plant. Trim or pinch the stem tips to encourage bushiness. It is important not to over-prune to the point where the plant’s vitality and vigor may be impacted.
