Establishment
4-6 weeksYoung transplant with small silvery foliage; compact mounding habit beginning to form
Water regularly but lightly until roots establish (4-6 weeks). Ensure excellent drainage. Protect from excessive wind. Light pruning to encourage bushiness.
Vegetative Growth
Spring through early summerVigorous foliage expansion with increasing mound formation; silvery-gray feathery leaves densify; plant reaches 1.5-2 feet height and width
Minimal watering once established. Pinch back growth tips in spring to encourage fuller, more compact form. No fertilizer needed; nutrient-poor soil is actually beneficial.
Pre-Flowering
Mid-summer to late AugustPlant reaches full size; foliage becomes denser and more refined; buds begin forming on terminal shoots in late summer
Continue drought conditions. Reduce watering to minimal levels. Do not fertilize. Allow plant to harden off for winter.
Flowering
August through SeptemberDelicate pale yellow flower spikes appear above silvery foliage; flowers are small and insignificant but add airy texture
Deadhead spent flowers if desired to maintain neat appearance, though flowers add ornamental value. Avoid overhead watering to prevent mildew.
Dormancy/Winter
October through MarchFoliage may fade slightly; plant becomes semi-evergreen; growth slows dramatically

Fun Facts
- 🌱 Lambbrook Silver is a hybrid artemisia (indicated by the × in its scientific name), bred specifically for ornamental use and superior foliage color compared to species artemisias.
- 🌱 The silvery-gray color of artemisia foliage comes from tiny hairs (trichomes) that cover the leaf surface, which also help the plant reflect heat and reduce water loss in hot, dry conditions.
- 🌱 Artemisia species have been culturally significant for thousands of years; the genus is named after Artemisia II, a 4th-century BC queen of Mausolus, and various artemisias are used in traditional medicines worldwide.
