Sweet Pea ~ Old Spice Mix (Lathyrus odoratus). Thankfully this gorgeous scented old variety was rescusitated before lathyrus breeders pushed it out of the trade in favour of the big buxom— and bland-smelling— modern varieties.
Annual sweet peas need cool weather, cool roots, and lots of fertile, deep soil. Dig the bed in the fall get ready to plant your starts (or seeds) as soon as you can push a shovel through in the spring. They can be started in a cold frame in really deep plug trays or 4-inch pots and plant them before the roots fill in. Although they dislike transplanting, the early start will encourage blooms before the hot weather sets in. Keep them watered as they sulk through summer and you'll likely get a second, quite vigorous flush in the fall.
