Ipoemoea, or Morning Glory as it is also known, is a half hardy annual whose wiry stems twine around upright supports. It has heart shaped leaves and large trumpet-like flowers that look great growing over trellises and fences in the summer with foliage that is light enough to make it perfect to weave its way through other shrubs and trees. The trumpet shaped flowers only last for a single morning but, once they start flowering in mid summer, they produce new blooms day after day.
The certainly aren't the easiest plant to grow but, if you can find room for them in a sunny, well-drained and sheltered spot in your garden they're well worth the effort. I'm growing 'Heavenly Blue' this year which produces lovely light blue flowers and can't wait to see the first flowers that should be here in July.
