Ipomoea purpurea, the Purple, Tall, or Common Morning Glory, is a species in the genus Ipomoea, native to Mexico and Central America. Like all morning glories the plant entwines itself around structures, growing to a height of 2-3 m tall. The leaves are heart-shaped and the stems are covered with brown hairs. The flowers are trumpet-shaped, predominantly blue to purple or white, 3-6 cm diameter. The plant is predisposed to moist and rich soil, but can be found growing in a wide array of soil types. It is naturalized throughout warm temperate and subtropical regions of the world.
Although it is often considered a noxious weed, Ipomoea purpurea is also grown for its beautiful purple and white flowers and has many cultivars. Common cultivars include I. purpurea 'Crimson Rambler' (red-violet blossoms with white throats); 'Grandpa Ott's,' 'Kniola's Black Knight,' and 'Star of Yelta' (blossoms in varying shades of deep purple with white or pale pink throats); and 'Milky Way' (white blossoms with mauve accents).
Morning glory is a common name for over 1,000 species of flowering plants in the family Convolvulaceae, whose current taxonomy and systematics is in flux. Morning glory species belong to many genera.Morning glories are decorative blooming vines that twine around fences, porch rails, and even other shrubs. Their prolific blooms announce the warmer weather of the summer months. It comes from subtropical South America and thus endures some cold.As its name suggests, the morning glory blossoms unfurl in the morning hours to greet the sun and then close later in the day as the sun gets hot; by evening, when temperatures are cooler, the blooms are tightly closed
