THIRTY nurseries will be offering unusual plants at this Sunday?s NCCPG Summer Plant Market in Tavistock. Specialist nurseries from Bideford to Brixham and Truro to Lyme Regis will be at Tavistock Pannier Market from 10am to 3pm with plants to give your garden colour and interest well into the autumn. A newcomer to the market will be Granny?s Meadow Plants from Colebrooke near Crediton with their attractive range of herbaceous perennials. National collection holders will include growers of such delights as Michaelmas daises, Streptocarpus, Viticella Clematis, grasses, herbs and alpines. Entry is £1 but free to NCCPG members.
