A wildflower (or wild flower) is a flower that grows in the wild, meaning it was not intentionally seeded or planted.
A perennial plant or simply perennial (from Latin per, meaning “through”, and annus, meaning “year”) is a plant that lives for more than two years. The term is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth from trees and shrubs, which are also technically perennials.
A shrub is distinguished from a tree by its multiple stems and shorter height, usually under 6 m (20 ft) tall. Plants of many species may grow either into shrubs or trees, depending on their growing conditions.
A vine in the narrowest sense is the grapevine, but more generally it can refer to any plant with a growth habit of trailing or climbing stems or runners.
Grasses, or more technically graminoids, are usually herbaceous plants with narrow leaves growing from the base.
In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height.
