The gardens open to the public on Friday 01 March and everyone who lives in Cornwall will be charged just £5 entry instead of the normal £7.50.
Recently hailing the early arrival of spring, the gardens have woken from their winter slumber and visitors can expect a feast for the eyes with the camellia and Asiatic magnolia trees bursting into flower.
Elsewhere, follow the woodland paths and explore the many glades full of historically important and rare plants, including 22 Champion Trees. There is also the opportunity to visit Trewithen's red squirrels in their specially built enclosure, and learn about the part they are playing in a project to re-introduce them back into the wild.
The Plant Centre will be open and, under the management of Head Gardener Gary Long, will be offering a range of plants, mainly propagated from Trewithen's own collection, garden accessories and staff will be on hand with expert knowledge and advice. In addition, the Tea Shop will be serving a range of home cooked fare including cakes, light lunches and cream teas.
Individual entry to the gardens costs £5 per adult for Cornish residents on production of proof of residence. Children under 12 go free. For more information, visit www.trewithengardens.co.uk or call 01726 883794.
