Most of the trees grown in gardens have a rounded or broad-spreading shape, and even more so if the trees are isolated and have plenty of space to fill. Big, broad trees are beautiful in their own right, of course, but are even more attractive when teamed up with some trees of upright shape. Trees of upright shape are often called pillar or pencil trees to denote the relative narrowness of their outline. They are also called fastigiate, which is the botanical term for trees of upright, narrow habit. There are very few trees of naturally upright habit, really just Italian cypress and some pillar junipers.
