Silver Mound

Artemisia schmidtiana 'Silver Mound'

shrub

Silver Mound is a compact, mounding ornamental shrub prized for its fine, feathery, silvery-gray foliage that creates a soft texture in garden beds. It grows as a low, dense mound and is valued primarily for foliage rather than flowers, though it produces tiny yellow flowers in late summer. This plant is excellent for adding contrast and a cooling visual effect to warm-colored plant combinations.

Growth Stages

1

Establishment

4-8 weeks

Young transplants establishing root systems with compact mounding growth habit beginning to form

Water regularly but allow soil to dry between waterings. Avoid overwatering. Provide full sun. Mulch lightly around base.

2

Vegetative Growth

Several months to 1 year

Plant develops dense, silvery-gray foliage in a tight mound form; height reaches 12-18 inches

Reduce watering frequency as plant matures. Maintain excellent drainage. No fertilizer needed; prefers lean soil. Pinch back growth in spring to encourage bushier form if desired.

3

Flowering

6-8 weeks

Tiny, pale yellow button-like flowers appear on short stems above the foliage in late summer to early fall

Flowers are secondary to foliage appeal. Deadhead spent flowers to encourage continued blooming and maintain compact form, or allow to bloom naturally.

4

Dormancy

3-4 months

Plant enters winter dormancy with foliage remaining ornamental; may show slight color variation in cold climates

Cease fertilizing. Ensure excellent drainage to prevent winter rot. Do not mulch heavily over crown. Allow to dry out between rare waterings.

5

Spring Renewal

2-3 weeks

New growth emerges in spring; plant returns to active growth after dormancy

Prune out any dead or damaged wood. Refresh mulch layer. Resume regular but infrequent watering. This is an ideal time for rejuvenation pruning if plant has become leggy.

Harvest Tips

Silver Mound is ornamental foliage; harvest foliage for arrangements by cutting stems as needed. Can be lightly pruned throughout the season to maintain shape. Cut back hard in early spring (remove 6-12 inches of growth) to rejuvenate leggy plants.

Fun Facts

  • 🌱 Silver Mound is named for its distinctly silvery, fine-textured foliage which can appear almost white in bright sunlight, creating a luminous quality in shaded areas of the garden.
  • 🌱 The plant's silvery appearance is due to tiny hairs (trichomes) covering the leaf surface that reflect light, a adaptation that also helps reduce water loss in hot, dry conditions.
  • 🌱 Artemisia species have been used for thousands of years; the genus is named after Artemisia II, a botanist and queen of Mausolus in ancient Caria.
