The morning glory is native to tropical America. The botanical name Ipomoea comes from the greek, ips means worm and homois means being like, because of its pale, worm like stem.
No frost as yet so these two morning glory plants are still flowering, the pale pink is 'candy pink' and the cerise is an unknown variety as a friend of mine kindly gave me the seeds. If you leave them to go to seed they may become invasive around the garden, I don’t mind as I like them, but funny how I hate its common cousin, the dreaded bindweed!
Small quantities of substances similar to the hallucinogenic drug LSD are found in the seeds of some species.
