Knowing your horticultural zone is essential to gardening—it gives you a head start to know what will and probably will not grow in your region. Using the hardiness zone map (above), you can determine your location's 'zone' and know which plants are most likely to grow successfully there. For example, a plant that is listed as hardy in zones 3-8 will more than likely grow well in a location within zones 3, 4, 5, 6, 7 & 8. However, if you live in a zone 2 region, that plant will probably not thrive.
