Blue Dawn Flower
Deciduous, Perennials, Vines
In this genus, ornamentals and edibles abound, from edible sweet potatoes (see Sweet Potato) to trellis-climbing morning glories and the sweet potato vines that fill out container plants so well.
Most have hard seeds; to encourage faster sprouting, nick the coating or soak overnight in water before planting. For annual display, sow seeds in place after frost danger is past; or, for an earlier start, sow seeds indoors, then set out plants 6–8 in. apart. Use morning glory vines on fence or trellis or as groundcover. Or grow in containers; provide stakes or a wire cylinder for support, or let the plant cascade. For cut flowers, pick stems with buds in various stages of development and place in a deep vase; buds will open on consecutive days. The morning glories listed here do not include the weedy plant known as wild morning glory or bindweed (Convolvulus arvensis). These are similar only in appearance.Ipomoea indica
Vigorous, rapid growth to 15–30 ft. Dark green, heart-shaped or three-lobed leaves. Clusters of 3–4-in., funnel-shaped flowers appear from spring into fall; blooms open bright blue, then fade to pinkish purple by the day’s end. Use to cover a large bank, a wall, or an unsightly fence or other structure. Blooms in one year from seed; can also be grown from cuttings, divisions, and layering of established plants.
