Wild Perennial Lupin (Lupinus perennis)

Native plant is a term to describe plants endemic (indigenous) or naturalized to a given area in geologic time.

This includes plants that have developed, occur naturally, or existed for many years in an area (e.g. trees, flowers, grasses, and other plants). In North America a plant is often deemed native if it was present before colonization.

Some native plants have adapted to a very limited, unusual environments or very harsh climates or exceptional soil conditions. Although some types of plants for these reasons exist only within a very limited range (endemism), others can live in diverse areas or by adaptation to different surroundings (indigenous plant).

Environmental conditions

Native plants form a part of a cooperative environment, or plant community, where several species or environments have developed to support them. This could be a case where a plant exists because a certain animal pollinates the plant and that animal exists because it relies on the pollen as a source of food. Some native plants rely on natural conditions, such as occasional wildfires, to release their seeds or to provide a fertile environment where their seedlings can become established.

Invasive and native plants

Human intervention

As societies move plants to new locations for cultivation as crops or ornamentals (or transport them by accident), a percentage may become invasive species, damaging native plant communities in the introduced range. Besides ecological damage, these species can also damage agriculture, infrastructure, and cultural assets. Government agencies and environmental groups are directing increasing resources to addressing these species and their potential interactions with climate change.

The rich diversity of unique species across many parts of the world exists only because bioregions are separated by barriers, particularly large rivers, seas, oceans, mountains and deserts.

Humans, migratory birds, ocean currents, etc. can introduce species that have never met in their evolutionary history, on varying time scales ranging from days to decades (Long, 1981)(Vermeij, 1991). Humans are moving species across the globe at an unprecedented rate. Those working to address invasive species view this as an increased risk.

Native plant movement

Native plant activists^[which?] support the introduction of ecological concepts and practices by gardeners, especially in public spaces. The identification of local plant communities provides a basis for their work.
