3-6 monthsYoung plant with sparse silvery foliage, slow initial growth. Roots developing.
Water regularly but allow soil to dry between waterings. Protect from extreme heat/cold in first season. Do not fertilize.
Vegetative Growth
6-18 monthsFoliage fills in, stems elongate, silvery color intensifies. Plant gradually increases in height and width.
Reduce watering frequency as plant establishes. Pinch back stem tips in early summer to encourage bushier growth. No fertilizer needed.
Flowering
6-8 weeks in late summer/fallSmall yellow or cream-colored flowers appear in terminal spikes. Blooms are inconspicuous but present.
Deadhead spent flower spikes to redirect energy back to foliage if desired, though flowers are not the main ornamental feature.
Maturity
Year-roundFully developed shrub (2-4 feet tall and wide depending on variety), dense silvery foliage throughout growing season.
Minimal water except during severe drought. Prune in early spring to maintain shape and remove dead wood. Extremely low maintenance.
Dormancy
December-February in cold zones; minimal dormancy in warm zonesIn colder zones, foliage may persist but growth halts. In warmer zones, semi-evergreen growth continues.

-
Remove affected foliage; improve air circulation. Fungicidal sprays rarely needed in dry conditions.

Harvest Tips
Silver Artemisia is grown for ornamental foliage; no harvest for food. Foliage can be cut anytime for fresh or dried arrangements. For drying, cut stems in mid-to-late summer before flowers fully open, bundle, and hang in cool, dry location for 2-3 weeks. Dried foliage retains silvery color indefinitely.
Fun Facts
- 🌱 Silver Artemisia is native to semi-arid regions of western North America and can thrive with less than 12 inches of annual precipitation, making it ideal for water-stressed regions.
- 🌱 The silvery appearance of the foliage comes from tiny, hair-like structures called trichomes that reflect sunlight, helping the plant reduce water loss and protect against intense UV radiation.
- 🌱 Many Artemisia species, including this one, have been used for centuries in traditional medicine and spiritual practices across multiple cultures, from Native American sweat lodges to Chinese acupuncture.
