Clickable Species Maps

• Click on an individual State/Province or to view native and naturalized species.
• Click on a USDA Hardiness Zone (lower left) to view plants commonly planted in that zone.
• This USDA plant hardiness zone map is based on USDA Miscellaneous Publication 814, "Plant Hardiness Zone Map," which was revised in 1965 and more recently in 1990. For our purposes, zonal subdivisions in the original map have been combined.
• Ornamentals are species (not varieties) that are commonly planted.
• For the original map, along with additional information, please visit the National Arboretum
