North American flora encompasses a diverse range of plant species found across the continent, including trees, shrubs, grasses, and wildflowers. The region's varied climates, from arctic tundra in the north to tropical areas in the south, support unique ecosystems. Notable plant families include Asteraceae, Fabaceae, and Pinaceae, which contribute to the rich biodiversity. Different habitats, such as deciduous forests, grasslands, and deserts, host distinct plant communities. Iconic species include the sugar maple, known for its vibrant fall colors, and the saguaro cactus, a symbol of the southwestern deserts. Conservation efforts aim to protect these vital ecosystems and their native species.
