Hydrangea arborescens
'Emerald Lace'

Hydrangea arborescens 'Emerald Lace' is an unattractive hydrangea with leaves like holly and a straggly, ungainly form. Perhaps, after some careful cultivation, it will look better in its second year..

Inflorescence: Lacecap type, 140mm across, with white fertile flowers in the centre surrounded by white sepals.

Pruning: H. arborescens ‘Emerald Lace’ can be cut back hard in autumn as this species will flower on new growth. They should be hard pruned (all shoots, branches, twigs) to about 15cm from the ground every year.

Propagation: In May or June detach a runner from the parent plant whilst still small and pot up. The runner should have several inches of root and two or three pairs of leaves. Keep damp and place in the shade.

H. arborescens is a native species of the eastern U.S.A., from Iowa to Florida and Louisiana.

Found by Stan Tyson, Illinois, USA in 1990.
