Description

Very vigorous and rather unruly, maintaining a clean stem has proven difficult, effectively disqualifying 'Sapporo Gold' for street use, consequently it is now promoted primarily as a hedgerow tree. The foliage is similar to 'Sapporo Autumn Gold', which has the same parentage.

Pests and diseases

'Sapporo Gold 2' (Resista) has a high resistance to Dutch elm disease.

Cultivation

The tree was registered in 1990 as 'Sapporo Gold 2' (Resista) and has been marketed by André Briant Jeunes Plants [2], Saint-Barthélemy-d'Anjou, as a hedging plant ever since.^[1]
