I have two purple sage bushes. They were originally planted, not for herbal purposes, but because of their leaf colour and fragrance. Over the years they have grown and grown and become pretty huge and I have loved the way they have trailed over the edge of the beds and down. However, they're getting too much now so yesterday I had a go at chopping one of them back. I'm no expert but I was quite pleased with the result, so today I'm having a go at the other one. I'm sure you can tell which is which in the photos above!
Oh - and they help to make the most delicious Christmas stuffing - so they're more than merely decorative.
