Salix alba 'Tristis' (Golden Weeping Willow)


Michael's Opinion

A favourite of designed streamside plantings the Golden Weeping Willow is a very majestic, broad canopied tree that can reach a height of 20 m. It is a very fast growing species that has a voracious appetite for water; roots have been known to clog water and septic lines. Since it is a fast growing species it is also weak wooded and as such causes constant litter problems and is very problematic during winter storms.
