2,5 - 3 m x 3,5 - 4,5 m
High adaptability to various types of soil. Because of the higher growth rate more poor soils should be preferred. Only limited tolerance to poorly-drained soils. Low susceptibility to chlorosis makes cultivating on sites with high pH level possible. The growth rate is clearly higher on heavy soils. The production of root suckers depends on the type of soil, but is mostly very low.
Reacts sensitively in container culture, therefore losses are possible while overwintering.
