Growing notes
- Bird-attracting white berries in late summer
- Brilliant red young stems through winter — coppice or hard prune in late winter for the strongest colour
- Spreads by suckers to form thickets — useful for stabilising stream banks and damp ground but allow space
- Extremely cold hardy — succeeds where most ornamentals fail
