Annual vines grow quickly and bloom profusely in one growing season. They can camouflage unsightly fences or walls, accent pleasing architecture, or soften harsh structural lines—and at the same time add color, texture, and height. Vines are ideal for creating a temporary, natural screen for privacy or against sun, wind, or unattractive views. They also can create a welcoming habitat for birds, bees, and butterflies.
