Cool weather crops can often take a light freeze and frost and manage without problems. They are often crops you can plant in the spring and fall as they love the cool weather.
Cool weather vegetable crops like nights that average in the 50’s, moving down into the 40’s or up into the 60’s at times. They like their days in the 60’s and 70’s. Once you get into the upper temperatures many of the plants stop producing, bolt to flowering for seed production or just die out.
Here is a list of cool weather crops I will keep updating. Leave comments for vegetables I need to include. The harvest ranges should match cool weather in your area. You can start most of these from seed and many do well as seed starts for transplants.
