 The tree's tall and rapid growth is a function of its shade intolerance.Grown in the full sun, the species tends to grow shorter, slower, and rounder, making it adaptable to landscape planting.In forest settings, most investment is made in the trunk (i.e., the branches are weak and easily break off, a sign of axial dominance) and lower branches are lost early as new, higher branches closer to the sun continue the growth spurt upward.
