Gardens of the Roseland Peninsula

St Mawes Holidays > Roseland Info > Things to do and see > Gardens of the Roseland Peninsula


Caerhays Castle, which is owned by the Williams family nestles in a secluded valley above Porthluney Cove and this 100-acres of woodland gardens is one of Britain’s horticultural treasures.  The Gardens are only open from 16 March to 29 May so you have to make the most of a visit.  South of Tregony, take the road to Veryan just after (or before!) the Jet garage.  Caerhays is well signposted.  The garden at Caerhays contains a combination of both spectacular spring displays of enormous tree magnolias, rhododendrons and camellias as well as a huge range of rare woodland trees and shrubs originating primarily from China. It therefore has plenty to offer the more enthusiastic gardeners as well as those who simply want to admire and appreciate the unique spectacle.  A must for lovers of magnolias and rhododendrons.

Poppy Cottage Garden

Located on the main road just north of Ruan Highlanes, this delightful small garden of 1 acre has been formed from a small uncared plot to one of the best gardens you will see of this size. If you are looking to design a garden on a long fairly narrow plot then you will get many good ideas here. Along one side the garden is split into a series of sheltered garden rooms whilst on the other side there are small sweeping lawns edged with colourful borders. This is a plantsman’s garden with brimming with bulbs, herbaceous plants, shrubs, exotic plants and of course poppies. Most of the plants are well labelled. There are plenty of places to sit and at the far end of the garden there is an area with unusual ducks and chickens.

Trewithen House & Gardens

Located off the A390 Truro to St Austell Road, just east of Probus.  The gardens at Trewithen are outstanding and internationally famous.  Best in Spring they have a magnificent collection of camellias, rhododendrons, magnolias and many rare trees and shrubs seldom found elsewhere in Britain.  A fine grass avenue leads up to the house bordered by large magnolias.  Further pathways take you around the garden where you can see tree ferns, azaleas and acers.  Many other features and plants including climbers.  A wide range of plants and shrubs are for sale at the plant centre within Trewithen Gardens.  The house is also open to the public.


Take a short hop over the King Harry Ferry and the famous Trelissick Gardens are located on the western bank of the River Fal. Owned by the National Trust, Trelissick Gardens are set in more than 400 acres of sweeping parkland with beautiful views of river and estuary. There are large collection of hydrangeas, camellias and rhododendrons together with sub tropical plants together with a national collection of azaras and photinias. In the dell there are tree ferns hostas and hellebores plus aromatic plants in a small walled garden. Open air music and theatrical events in season are held regularly. There is plenty to see and the walks around the park and woodlands are wonderful.
