Eupatorium

(Common Names: Knitbone, Joe Pye Weed)

Tall imposing plants grown for their fine foliage and late summer / autumn heads of flower.  Grow in damp soils for tallest plants. In our experience they grow well in dry soils but don't get so tall, nor spread so fast. Best with their heads in the sun. Slow to come through in spring so be patient

Propagate by division in spring. The rootstock is quite hard and the divisions can look like dead sticks in early spring but little buds soon show.

We don't know of any specific pests. If you've got a sluggy garden then protect them until about 6" / 15cm tall.

A member of the Asteraceae family.

Eupatorium maculatum Atropurpureum

This variety has darker stems than the species and looks good at the back of the border. Fluffy pink flowers from late August onwards. 5-6ft / 150-180cm tall, but self supporting.

Can be grown en masse at the back of the border or as a dramatic and architectural spot plant at the front of the border, especially at the end or on a corner where it forms a towering column of leaf and purple stems clothed with flower from top to bottom.

RHS Award of Garden Merit.

Eupatorium maculatum Baby Joe

Same large heads of purple-pink flowers but half the height to the species.
