delicious & blue

I love seeing bees on the flowers in our garden.  The nectar must be delicious as this busy bumblebee just couldn't get enough of it.
No idea what this plant is called but it always reminds me of our former neighbour who gave a cutting & now it spreads in our garden... it's nice to look around, seeing plants friends have given me as a present or a cutting years ago, happy memories growing in every corner.  :-)
