Artemisia frigida (Fringed Sage)

From CONPS: A perennial, tap-rooted sub-shrub with soft, feathery, highly aromatic silvery-green foliage that hides a woody base. Small, deeply divided leaves are the reason for the common name. Tiny silky hairs cover the leaves, giving the plant its distinctive silvery-green cast and making the whole plant soft to the touch. Stalks rise above the foliage in mid-summer to sport a multitude of tiny yellow flowers, which spew an abundance of pollen. (Allergy sufferers beware.) Flower stalks can be cut down to encourage new growth and maintain a more mounded overall shape. Mature height 8" - 12", space 12" - 18" apart. Prefers full sun and well drained soil.
