Another Garden Blip

A few years ago I stole  took a cutting of a plant that was spreading over a corner of the garden in the AirBNB cottage we were staying in. It looked so good and I thought a little bit would not be missed.
Well it's been sitting in my garden doing nothing,not dying but not thriving, nothing like it's original home. This year however this flower appeared, not stunning maybe but very pleasing. No idea what the plant is but I certainly am more impressed with it now.
