Trimmed budleia

I saw a budleia that had been trimmed like this when I was walking around the village and thought it was a good idea. I have three in a row that we inherited with the garden. I'm not a big fan but they cover a nasty wall (well, mostly) and the butterflies they attract really are amazing. I didn't have the heart to remove them so just keep this one, that was forever overtaking the patio, neatly trimmed in shape. It doesn't flower (the others do) but it does keep its leaves over the winter which is a bonus.
