USDA Hardiness Zone 13b

Zone 13b is a zone in the USDA Hardiness climate zone rating system. The USDA Hardiness system can be useful to gardeners in establishing if certain plants are suitable for your garden's microclimate and was originally devised by the US department of agriculture. There are currently 5 gardens being tracked on Folia that are in USDA Zone 13b.

Typical example plants that tend to grow vigorously in this zone include Sunflower, Tomato, Broccoli, Cucumber, Garden Cosmos, Sweet pea, Stevia, Thyme and Ornamental pepper.

Some locations recently identified as being in this zone include Barcelona (Spain).

If your area is defined as within 13b, you typically get low temperatures of between 12°C (54°F) and 12°C (54°F)

Zone 13b has a corresponding Sunset zone of 25, H1, H2.

Due to large differences in average temperature, USDA Zone 13b is typically known as Zone 7 in Australia.
