Ipomoea purpurea (Morning Glory)

Valued as an exotic climber for the garden, Ipomoea purpurea (Common Morning Glory) is a particularly pretty annual vine noted for its luminous heart-shaped foliage and attractive rich purple-blue trumpet-shaped flowers. Opening in the morning to reveal their white throats, the flowers, 2-3 in. (5-7 cm), close in the afternoon, hence the common name. Morning Glory produces new flowers daily and blooms continuously from early summer to early fall.
