Establishment
4-6 weeksSmall transplant with silvery foliage beginning to develop

Vegetative Growth
Spring through mid-summer (3-4 months)Plant develops dense silvery-gray, feathery foliage; forms mounding habit
Minimal fertilizer needed; avoid rich soil. Prune occasionally to maintain compact shape. Reduce watering frequency as plant matures.
Flowering
Late summer to early fall (6-8 weeks)Small, inconspicuous yellow flower clusters (panicles) appear above foliage
Flowers are secondary to foliage interest. Deadheading is optional but promotes bushier growth. May flower repeatedly if moisture is provided.
Maturity
Ongoing (year 2 onward)Fully developed mounding shrub, typically 12-18 inches tall and 24-36 inches wide
Requires virtually no maintenance once established. Cut back old growth in spring if desired. Extremely salt and wind tolerant.

Fun Facts
- 🌱 Beach wormwood is native to coastal regions of northeastern North America, Russia, and Japan, demonstrating remarkable adaptation to harsh salty, sandy environments.
- 🌱 The common name 'wormwood' derives from the genus Artemisia, though beach wormwood is less bitter than other wormwood species and is primarily grown for ornament rather than the medicinal compounds found in common wormwood.
- 🌱 Its silvery coloration is due to fine hairs (trichomes) on the leaves that reflect light and reduce water loss, a clever adaptation that also gives it exceptional salt and drought tolerance.
