Silver Mound Artemisia (Artemisia schmidtiana ‘Silver Mound’)
Silver Mound Artemisia also known as Wormwood, Ghost Plant, Mugwort this small herbaceous perennial, native to Japan, is hardy in zones 3 to 7. Growing as a spreading mound this plant matures to a height of 12″ and spreading 18″ wide.
A perennial border powerhouse chosen for its spectacular silvery green, fine textured foliage. Silver Mound should be grown in full sun and well drained soil. Prune early spring. In the disease and pest category rust seems to be the main problem.


I live in Minneapolis, Minnesota. The silver mound is very nice looking up until August- September. It opens in the top middle and looks like it needs to be trimmed and prunned. Any advice?
Artemisia are ideally pruned in the Spring. When pruned in the fall new growth is encouraged and does not have time to harden off before the Winter comes rolling in, this results in plants freezing.
Can silver mound be divided to create more plants from the original plant? We live in Duluth, Minnesota and love these plants!
Thanks for any tips to help us . . .
Sincerely,

Propagation is best done by stem cuttings. Cuttings can be easily rooted during the Summer. Worm wood rarely spreads, hence cuttings rather than division of the plant prove to be the most effective method of propagation.
