Lacy foliage provides a pleasant cucumber fragrance. My favorite artemisia. It has finely textured, dusty-gray foliage and constant lemon scent that's stronger when crushed. French tarragon substitute. It flowers with yellow blossoms in late summer and early fall.
Some people call it Mexican mint marigold.
I especially like the creeping thymes which make fragrant ground covers. Use between stepping stones, on borders and in stone pockets. Lacy, fern-like foliage and is an evergreen perennial in warmer climates. Colorful flowers on tall stalks which bloom in early summer. Fertilize twice each year with mild organic fertilizer.
