Site Requirements
This is a large shrub or bushy tree which colonises mountain areas after disturbance. Best growth is found on freely draining moderately dry to fresh soils of poor to medium nutrient regime. It is not tolerant of drought, is not suited to very wet or alkaline soils, and has limited tolerance of exposure. It is cold hardy in Britain and frost tolerant. It grows in mixture with other tree species and can be used as a nitrogen fixing nurse species.
