I'm thinking of digging up our Golden Rod and planting Peonies as they suit my colour scheme better.
The golden rod are mixed up with where we have lots of bluebells in a border, so will have to wait until the bluebells have flowered.
Are Peonies hard to grow ? i think I have one in the garden, which didn't flower last year so might move that. They seem quite expensive, so do they spread easily or can you divide them up after a few years. What is the most cost effective way to fill an area about 1m deep by 5m long ?
