Upright Main stems and branches emphasize upward growth. An upright tree can still develop a broad canopy. Spreading Branches extend outward to form a broad canopy. The tree does not have to be wider than it is tall. Weeping Branches or branchlets arch or hang downward. The tree can still have an upright trunk. Rounded The crown has a rounded outline. This describes the overall shape rather than the direction of each branch. Dwarf A cultivar with a smaller natural stature than typical forms of its species. Dwarf describes size, not branch direction or a fixed height limit; it does not automatically mean slow growth.
