Which term describes the characteristic of plant that is round like a globe?

The term that accurately describes a plant characteristic that is round like a globe is "spherical form." This term specifically refers to the three-dimensional shape of the plant, emphasizing its roundness and similarity to a sphere. In botany and horticulture, understanding plant morphology is essential, and "spherical form" conveys the inherent geometry of such plants effectively. This term is commonly used to classify plants based on their physical appearance, particularly when discussing ornamental plants or landscape design.

While "rounded form" may seem appropriate, it does not specifically convey the exact shape as accurately as "spherical form," which is standard terminology in describing plants exhibiting this characteristic. The other terms, including "abbreviated form" and "horizontal form," do not relate to the description of roundness and therefore do not apply to this context.
