Sweet Pea
Early Spring: Kick off the growing season with this cool-season favorite that's easily grown from seed. Sweet pea vines climb by tendrils and need a trellis. Plants top out at about 6 feet. In Zones 8 and 9, tuck seeds into soil in late fall for spring blooms; elsewhere, sow in early spring. Plant along a trellis or fence line, or use to add color to a vegetable garden or cutting garden.
