Trees and Shrubs

Every plant species has certain environmental requirements for sunlight, temperature, soil conditions, moisture, drainage, exposure, etc. that determine where it can grow successfully. The idea of plant communities – of plants with similar requirements growing together in specific places on the landscape – originated near Walnut Canyon in the late 1880s.
