Quick facts and care essentials
• Full sun
• Regular watering
Delightfully fragrant sweet peas bloom in shades of pink, purple, blue, salmon, and red, as well as white, cream, and bicolors. Plant size varies: bush types grow 1 to 3 feet high, while vines can reach 5 feet or taller. Space seeds or plants 6 to 12 inches apart.
Provide a trellis or other support for climbing types as soon as you plant them, since seedlings need support as soon as the tendrils form.
