Rue
Ruta graveolens
Even if it didn't bloom, rue would be worth growing for its foliage alone. The bright blue-green leaves are deeply divided, giving the whole plant a delicate, lacy look. In midsummer, the clumps are accented with clusters of bright yellow-green flowers. Good drainage is essential for healthy growth. Plants grow 2 feet tall. Zones 5 to 9.
Yarrow
Achillea millefolium
Common yarrow produces flattened clusters of red, pink or white flowers on slender stems clad in feathery green foliage. These summer flowers are great for fresh or dried arrangements. If you prefer yellow flowers, you could substitute another species or hybrid. Plants are usually around 2 feet tall. Zones 3 to 8.
