Uses
Dried Flower Arrangements
CraftSilvery artemisia is a staple in dried floral designs and wreaths due to its long-lasting silvery foliage that adds texture and contrast. The fine, feathery texture complements bolder dried flowers and grasses. [source]
Herbal Tea & Flavoring
CulinaryThe leaves can be used to make aromatic herbal tea with a slightly bitter, artemisia flavor, and historically have been used as a bitter in beverages. Use sparingly as a culinary herb due to potency. [source]
Traditional Herbal Medicine
MedicinalUsed in traditional folk medicine for digestive support and as a mild antimicrobial; some Native American tribes used it ceremonially. Modern use is largely traditional; consult practitioners before medicinal use. [source]
Moth & Insect Repellent
HouseholdThe aromatic oils in silvery artemisia have been traditionally used to repel moths and insects from stored textiles and clothing. Dried leaves can be placed in sachets in closets and drawers. [source]
Pollinators & Beneficial Insects
WildlifeThe late-summer flowers attract bees, butterflies, and other pollinators, providing nectar when other food sources are diminishing. The plant also serves as habitat for beneficial insects. [source]

Harvest Tips
Cut stems for fresh or dried arrangements anytime during the growing season; harvest before or just as flowers open for best dried foliage quality. Cut stems to 6-12 inches to encourage bushier regrowth. Foliage is most aromatic and silver in mid to late summer. Dry bundles upside-down in a cool, dark place for 1-2 weeks for dried arrangements.
Fun Facts
- 🌱 Artemisia ludoviciana is native to western and central North America and has been used by Native American tribes for centuries in ceremonies, medicine, and as an insect repellent.
- 🌱 The silvery coloration of the foliage comes from fine hairs (trichomes) that cover the leaves, which also help the plant reduce water loss in dry conditions and reflect intense sunlight.
- 🌱 Silvery artemisia is closely related to tarragon (Artemisia dracunculus) and wormwood (Artemisia absinthium), all belonging to the same genus known for aromatic and medicinal properties.
