Eupatoriums Rugosum Chocolate or hemp agrimonies bear handsome dark purple brown foliage that will gradually fade to green as masses of tiny white flowers appear in late summer. Perfect for dry shade, these perennial plants will add depth to the garden border and will mix especially well with other perennials such as achilleas, asters, euphorbias, geraniums and phloxes or with silver grasses. They are magnets for bees, butterflies and other pollinating insects.
Plant in moist, alkaline soil in partial shade. Protect from frost as this may damage new growth.
Eupatoriums are supplied in 9 cm pots. Always unpack on arrival and store in a cool place until ready to plant.

Snails and slugs:these pests enjoy munching on young shoots, stems, leaves and flowers. Watch out for damage!
