Name: Sweet Pea (Lathyrus odoratus)
Growing details: Sweet Pea seeds should be planted in late fall (October-November) in order to bloom in the spring. For those living in areas with particularly harsh winters, wait until late winter or early spring (when the ground is no longer frozen) to plant sweet pea seeds. Sweet peas grow best in areas with full sun exposure and soil that is on the alkaline side.
Varieties: As of 1900, there were roughly 300 varieties of Sweet Pea. Today, that number is exponentially higher!
Cost: Sweet pea seeds are widely available and usually very affordable, sold from around $2-5 a package.
