Peas are a cool season crop that produce an abundant harvest (and the perfect garden snack) when grown in the right conditions. There are many different types of peas to choose from, including snow peas and sugarsnap which have a crisp and crunchy pod that can be eaten whole, or shelling peas, grown for their sweet and tender peas inside. Peas come in either traditional climbing form which require a trellis, or bush varieties that are great for small spaces and gardening in containers.
