What are the US hardiness zones?
Zones range from Zone 1 (coldest) to Zone 13 (warmest). USDA zones are based on the average annual extreme minimum winter temperature. Each color represents average coldest temperature in 10°F zones. These zones provide a convenient way to communicate and compare the climates within the United States. Alaska, our largest state, includes 8 zones, ranging from 1 through 8. What do the USDA planting zone numbers mean? The numbers correspond to the average annual minimum winter temperature for each region, indicating which plant species can survive through winter.The Royal Horticultural Society has developed a hardiness rating system that classifies plants in accordance with the minimum temperature they can withstand. This rating system runs from hardiness level H7 (plants that can survive temperatures below -20°C/-4°F) to H1a (plants that must be kept above 15°C/59°F).The USDA plant hardiness zones are the most widely used system globally to determine planting zones. The entirety of the UK falls within USDA planting zones 6-9, which are based on average winter temperatures.The plant hardiness zones are rated 0 through 9, based on climate conditions such as temperature, precipitation and frost duration at locations across Canada.

Each color represents average coldest temperature in 10°F zones.Zone 0 covers the coldest parts of northern Canada, where only the hardiest of plants can grow, while Zone 9 covers much warmer parts of Vancouver Island, where a wider variety of plants can grow, including certain palms and citrus varieties. These hardiness zones are uniquely tailored to our landscapes and climate.
What USDA zone is Melbourne, FL?

This is a change from the 2012 USDA Hardiness Zone Map which has Melbourne in Zones 9b (25°F to 20°F) and 10a (30°F to 25°F). Because Florida lies so close to the equator, it receives stronger sunlight than the rest of the country. If you shine a flashlight on a globe, right in the middle, the area where the light is the brightest represents the areas where the sun’s radiation is most concentrated, and this is responsible for creating heat.Location & Shape. We all know from the third grade that the closer you are to the equator, the hotter it becomes and for the continental US, Florida is the closest state. So, it would make sense for Florida to have a hot climate. Hawaii though holds the number one spot for distance to the equator for the entire country .Most of the state is classified as a humid subtropical climate that experiences extremely long, warm, typically humid summers and mild, cool winters making Florida planting zones some of the higher ranges. Southern Florida has a tropical climate.
