Morning Glory

I went with my daughter to visit my niece and her family in the Colchester area today. A long drive there and back. She has moved house and this flower is in her wild garden. She is going to change a few things to the house and so the garden is being redesigned next year.
I just cant remember their name at present and yet I told her what they were derrrr. Getting old.
Thanks to Lindee for reminding me of the name. I’ve put it in the title.
