Home to some of the most outstanding beauty spots in England. From white sandy beaches to subtropical gardens. As well as an abundance of historic sites. It’s no surprise that the National Trust in Cornwall has over 50 places to visit across the county.

With its mild coastal climate, Cornwall is home to some of Britain’s most spectacular gardens. Best known are the great gardens of Cornwall dating back to the 19th century and built on the fruits of Victorian plant hunting expeditions. But there is great variety there too. From woodland gardens to landscaped parkland to sub-tropical glades, there is something of interest to even the most serious horticulturalist.

More than half of the Cornish coast is owned by the National Trust. And much of Cornwall’s industrial heritage has also been preserved by the charity with the purchases of tin mining sites and fishing coves. With knowledgeable staff and volunteers on hand. The places that they manage are perfect for all ages for discovering the sights, sounds and stories of Kernow (Cornwall in Cornish). Here we look at just a few of Cornwall’s best gardens in no particular order.

Caerhays Castle and Gardens, Saint Austell

Situated on the Roseland Peninsula, not far from Mevagissey is the beachside ‘castle’ and estate of Caerhays. The gardens are mainly attributed to the bravery of J.C Williams who scoured the world for exotic species such as rhododendrons, azaleas, magnolias and camellias. Open from March to May, this is when the gardens are at their best.

Lost Gardens of Heligan, Saint Austell

Also located near Mevagissey and brought back to their former glory by Tim Smit of Eden Project fame are the Lost Gardens of Heligan. There are several gardens within Heligan, including four walled gardens, Japanese and Italian gardens and the ‘Jungle’ with its sub-tropical plants.

Trebah Garden, near Falmouth

Rated one of the top 80 gardens in the world, this spectacular 26-acre garden easily makes it onto the list. Trebah Garden descends 200 feet through a steep valley to a private beach on the River Helford. It is well stocked with sub-tropical and exotic species imported by Quaker polymath Charles Fox. Over time, the gardens were neglected. However, in 1981, they were bought by Tony and Eira Hibbert, who spent the next 22 years restoring them to their former glory.

Tresco Abbey Gardens, Isles of Scilly

The mild climate of the Isles of Scilly makes it one of the only places in the UK where such a range of tropical plants can survive in the open. Not only do banana and citrus trees grow here, but they also regularly produce fruit! The gardens were originally planted by Augustus Smith in the 19th century in the grounds of the ruined abbey. The combination of ruins, sea vistas and unusual exotics make this a standout garden.

Trewithen Gardens, near Truro

Set in the heart of Cornwall, Trewithen is a large estate surrounding an impressive and elegant 17th-century manor house. Trewithen means ‘house of the trees’ and this could refer to both quantity and quality – the garden boasts 24 ‘champion trees’ as well as woodland walks and picnic areas. There is also a working nursery at Trewithen propagating in excess of 1500 species.

Trengwainton Gardens, near Penzance

The garden at Trengwainton was begun in earnest in the early 19th century. However, the features that define and set this garden apart mostly date back to the first half of the 20th century by the Bolitho family. Many exotics were imported from the Far East, including magnolias, camellias and the rhododendrons which line the drive. There are woodland walks through tree fern glades and a very impressive walled kitchen garden. Also worth a visit to the tea rooms – pricey, but good food and set in a walled garden of its own. The gardens are National Trust managed whilst the house remains private.

Glendurgan Garden, near Falmouth

Just down the road from Trebah is yet another fantastic valley garden leading down to the sea. This is one of the best-known sub-tropical National Trust gardens in Cornwall, featuring exotic flowers, bamboo and huge tree ferns. Spanning three valleys, the lush jungle-like gardens are peppered with enchanting trails which wind their way through a myriad of tropical delights including a giant tulip tree and the garden’s famous laurel maze, originally planted in 1833.

There are numerous fantastic viewpoints looking out over the Helford River and a walk to the bottom will take you to the pretty fishing village of Durgan. The main garden has many fantastic trees along with numerous rhododendron, magnolias, camellias and hydrangeas. There are a number of features, including a laurel maze, the ‘old school room’ and Holy Corner, with its selection of trees. Again, the National Trust manage the gardens at Glendurgan whilst the house remains private.

With dog walking, exploring, and 300 acres of beautiful woodland and coastline, Glendurgan Garden has a tonne of options for you. With a garden conservatory, ample dog walking, there’s plenty to see, and there’s also a tea house on site. And also, with a 180-year-old maze and stunning views, you have all the ingredients for a stunning day out.

Eden Project, Saint Austell

There is no denying the Eden Project’s iconic status. Opened in 2001, Eden claims the title of being the world’s largest greenhouse. That would, however, be selling it short. The two ‘biomes’, as they are called, are a series of interconnected domes divided into a tropical and Mediterranean region. These contain plants and trees representative of the region, with a further temperate region contained in the outside area. The Eden Project sits awkwardly between being an educational/environmental centre and a tourist attraction.

Cotehele, near Saltash

Garden with a vast number of plants, that is filled with nature.
Image found on The Cornwall Guide

The fantastic Tudor house at Cotehele is surrounded by both formal and natural gardens. To the front of the house is a terraced garden, whilst to the rear, there are orchards and a grand lily pond. Leading down to the riverside is a valley garden with a medieval stew pond and dovecote. There are also miles of woodland walks leading down to and along the banks of the River Tamar and Cotehele Quay.

Barbara Hepworth Sculpture Garden, Saint Ives

Unlike the great gardens of Cornwall, the Barbara Hepworth Sculpture Garden is not awash with plants from the four corners of the globe. It is a peaceful oasis of art and nature away from the crowds in the bustling town of St Ives. The garden features bronze, stone and wood sculptures by one of Britain’s most important 20th-century artists. Whether accidental or not, the forms perfectly complement the mainly sub-tropical plants.

One of the best-preserved and presented National Trust houses in Cornwall, Lanhydrock is a grand Victorian country property in Bodmin with fifty beautiful rooms to explore.

It has even starred in Poldark as Ross and Demelza’s beach at Nampara. Take a dip in the crystal-clear sea and, at low tide, explore its mysterious caves and blowholes, including one named the Post Office for its ability to create enough suction to draw a letter into it!
