Additional Information

Handsome tree, distinctive for its regular branching, spreading to horizontal to pendulous, from top to bottom of the tree. This effect is partly lost when lower limbs must be removed for traffic underneath. Requires an acidic soil and is subject to severe iron chlorosis on calcareous soils. This can be corrected but it means additional maintenance.
