Almost there!

The wall is almost done and dusted now. I'm just working on the border above the wall. Mum and I went to Dobbies today to buy lots of herbs which I'm planning on planting out by the wall. Mum's new flat has a lovely balcony, so we also bought a couple of pots and some lavender.

This is a desperate blip, I'm afraid. Can someone tell me the name of this flower? Many thanks!
