White mugwort and its cultivars are erect, clump-forming perennials which typically grow up 4 to 5 feet tall and wide. They have upright, branched, terminal sprays of loose panicles of creamy white flowers which bloom atop stiff, dark mahogany stems in late summer. Stems usually do not need staking. Pinnately divided blackish-green leaves have coarsely toothed segments. Most artemisias have non-ornamental flowers and are grown primarily for their attractive silver/gray foliage. By comparison, the white mugworts have attractive flowers and green (blackish-green in the case of this cultivar) leaves. They generally require more water than their silver-foliaged-kin.
Best grown in fertile, loamy, moderate to moist, well drained soils in full sun. Excellent soil drainage is essential for growing this plant and it does poorly in moist to wet soils as plants are susceptible to root rot. Plant stems tend to flop in the summer, if over-fertilized, over-watered, or receive too little sunlight. Prune plants in early spring to tidy, being careful to leave sufficient numbers of live buds on each stem to facilitate bushy growth. Never prune stems to the ground. Foliage may also be lightly sheared in summer to shape, but avoid pruning in fall.
