That flower is a honeysuckle and I can't believe it's blooming this time of the year! I have a different variety that grows all over the place at Toad Hall and makes late Spring early Summer smell like Heaven.

I planted a new variety on my pergola I made this Spring and it is that exact colour of the one you show, only thing was it had no scent when it bloomed :( Oh well.

Have fun with your chalk.
