What do they mean when they write that a plant is hardy to zones 10-12? Is it 10 or 12 or is it as low as 10 and as warm as 12?
When you see a plant that is listed as hardy to zones 10-12, it means that the plant can survive in areas with an average annual minimum temperature of 30°F to 50°F. Zone 10 is the warmest of the USDA plant hardiness zones, and zone 12 is the coldest. So, a plant that is hardy to zones 10-12 can survive in areas that have both warm and cold winters.
It is important to note that these hardiness zones are just a general guideline. The actual temperature that a plant can survive in will depend on a number of factors, such as the amount of sunlight it receives, the type of soil it is planted in, and the amount of water it gets.
