An Overview of Big Island Botanical Gardens
Plant Diversity and Climate
The quantity and variety of plants and flowers that call the Big Island of Hawaii home is truly astonishing. Some of the Big Island botanical gardens have over two thousand varieties of plants growing on their grounds. This diversity is largely due to the wide range of climate zones across the island, mixed with the consistent temperatures of those zones. The Big Island possesses the highest concentration of climate zones of any place in the world: 4 out of 5 Major climate zones and 10 out of 13 sub-zones. The climate diversity makes it the perfect setting for incredible botanical gardens to thrive all around the island.
Plant Hardiness Zones
Plant hardiness zones identify the location of environmental conditions under which a species or variety of plants can successfully survive and grow. Hawaii is one of the warmest areas on the USDA map with 9 plant hardiness zones. These zones are determined by the average annual extreme minimum temperature. For instance, the Kona Coffee belt lies in Hardiness Zone 11b & 12a with a minimum average low of 45-55 degrees, perfect for growing world famous Kona Coffee.
