A few posts back I spoke about hoping to cut back our buddleia ‘Blue Knight’ (also called ‘Blue Horizon’). To my delight, we have actually managed to achieve this, due to a couple of hours of very welcome sunshine on Saturday. First, let’s show you what the flowers look like; they are as blue as a buddleia gets, and the colour goes very well with the eyespot on the hindwing of the Peacock butterfly.

So here are the photos of cutting it back. I forgot to take a shot of the whole bush before we started, but the left-hand shot is of the job half way through, when some of the full height branches were still in place: I estimate they must have been about 12′ (3m) tall. By the time we’d finished, about 3′ (1m) was left, and we probably should have taken it down a bit further still, but there was so many nice leaf buds on one branch, I couldn’t bear to cut them off.

The cat wasn’t impressed – he stayed fast asleep.
