Artemisia ludoviciana 'Valerie Finnis' (Valerie Finnis Silver Wormwood) - A low, spreading sub-shrub/perennial that grows to form mounds to 2 feet tall by 4 feet or more wide (spreads slowly in heavier clay soils but runs more freely in lighter sandy ones) with large white-gray felted aromatic lance-shaped leaves that are lobed near the tips and on stems of the same color. In mid-summer appear the clusters of small yellowish to cream-white flowers that rise just above the foliage - flowers while interesting, are not that attractive. Plant in full to part sun (plants get floppy with too much shade) with occasional to very little irrigation - drought tolerant, once established. Completely dormant in winter and hardy well below 0°F and can reportedly be grown down to USDA Zone 4a (-30°F) and some say even to USDA Zone 1 (-50°F). Give a hard annual cutting back to the ground to keep tidy and prune off flowers to rejuvenate growth. This plant is not attractive to deer and tolerates poor or dry soils so long as they drain well.
