Ipomea
Common name: Morning Glory or Mina Lobata
Overview:
Ipomoea purpurea has many cultivars, and is a plant that some people consider to be a noxious weed, whereas, others will grow it because they find its beautiful purple and white flowers appealing.
It is a vigorous climber native to Mexico and Central America that requires a sheltered sunny position and light, rich soil.
They can grow to a height of 2-3 metres (6-10ft) and therefore will require the support of a trellis, canes or wires fixed to a wall.
The stems are covered with brown hairs and the leaves are heart-shaped.
The 35-40mm (1½") diameter flowers that appear from July to September are trumpet-shaped, and predominantly blue to purple or white.
Deadhead the flowers regularly to prolong flowering season.
