Eupatorium (Agrimony)

Plant in good soil in sun or shade.

The variety 'Chocolate' has purple new-growth and purple flowers.

Seed-saving
In all Eupatoriums, the flowers brown and fall off and show a casing in which blackish nutlets with tiny white parachutes can be found. Sometimes it takes 3 weeks from flower decay to viable seeds, so be sure to be patient with seed-collecting, waiting until the first frost. Remove entire stems and shake them into a bag. This can be stored in a cool location over the winter for spring seed-starting.

Dividing
Most Eupatoriums have clumping roots. Dig up plants to be divided in the spring and locate crowns to cut or freely break off of the main plant, or divide by seperating the clump down the middle. This should be done just as the buds on the surface are beginning to green.

In the case of E. rugosum (White Snakeroot) the roots form snaky rhizomes. Once the plant is dug up, locate crowns developing around the main plant, and cut them off for planting in other parts of the garden or giving away to friends.

Companions
Eupatoriums make a nice association with silver-leaved plants, Ornamental Grasses, Malva, Physostegia, Stokesia, and most fall flowering plants like Asters, pink Coreopsis (C. rosea and C. rosea 'American Dream'), Boltonia, Perovskia and Sedum 'Autumn Joy', 'Moerchen' or 'Brilliance'. Plants are late to emerge in spring and make an excellent cover for ripening Daffodil foliage.
