The Toma Verde Tomatillo is a very cold tomatillo. Sometimes called a husk tomato, you can start these 10 to 12 weeks before last frost. They will take a frost either in the early season or late season. These are a great Heirloom garden seed. Putting up a trellis will make harvest an easy task. Pick when the fruit is touching the husk. A must have in any garden--Happy growing!!!
