Cucumber (Cucumis sativus) is a widely cultivated plant in the gourd family. Our packs have around 300 seeds in them and around 1000 an ounce. Cucumbers are not cold tolerant, and don't transplant well either. These are great for a trellis! If you live in a long growing season area, you can do 2 or 3 plantings about 1 month apart. This keeps you having fresh cucumbers all the way until fall!
