What form of tree growth is described as having branches that droop towards the ground?

The form of tree growth known for its branches that droop towards the ground is referred to as "weeping." This growth habit results in a distinctive appearance, where the branches arch downwards, often creating a graceful and cascading effect. Weeping trees are typically chosen for ornamental purposes due to their unique aesthetic appeal. This characteristic can be found in several species, such as the weeping willow or weeping cherry, which showcase this trend prominently.

In contrast, other growth forms such as vase-shaped involve upward and outward branching that creates an open canopy, while upright trees display vertical growth with branches that extend upwards. Pyramidal trees generally have a conical shape with a symmetrical growth pattern, where branches grow outward at various levels from the trunk but remain relatively upright and do not droop. Understanding these growth forms helps in the selection and placement of trees for landscaping and horticultural purposes.
