North east dry, stony bank with acid soil
help! We have partly planted a bank with rhododendrons, blueberries, ground cover roses and heather. Any suggestions for low ground cover with colour, ive looked at alpines but don’t think they will survive. I forgot to say we live 500 feet up on the edge of exmoor! I look at other people’s gardens with envy and hope someone can point me in the direction of some suitable plants! Also suitable bulbs! Thanks.
