Strikingly beautiful clusters of Yellow flowers are gathered into flat-topped flower heads. The 1-3 ft. tall plants may occur singly or in clumps. The lower leaves are divided into three twice while the upper leaves are divided once. This makes the plant a little course looking but gives the garden structure.
The caterpillars of Black Swallowtail butterfly feed on the foliage of this and other members of the Carrot family. Various kinds of insects visit the flowers primarily for nectar, especially small bees.
The plant blooms for quite a long time. The yellow blossoms really lighten and brighten up the garden. The seed heads turn purplish in late summer. This adds more interest and beauty to the garden.
You can use Golden Alexander in a perennial border, rock garden and it is an outstanding candidate for a rain garden. Splendid companions are Red cardinal flower, Joe Pye weed, Swamp Milkweed, and Asters for a rain garden. In a more wooded setting try Virginia Anemone, Bowman’s Root, Ferns, Amsonia and Foam Flower.
Golden Alexander prefers light shade to full sun. It does well in moist well drained soils.
