Butterfly Bush

Or should that be Insect Bush?
Shame I didn't capture a Butterfly on the flower.
I would love more colours in my Garden, I have seen a Yellow one like this one, also a Yellow Buddleia that I like.
I'm hoping to get some help this Sunday with the garden.
Also I'm wondering whether to plant things in Boxes, I'm sure it would be like planting in Toilet Roll Tubes, but on a bigger scale.
