Horticultural expert and plantswoman extraordinaire Carol Klein will officially open the Blenheim Palace Flower Show on Friday, June 22nd.

The hugely popular BBC Gardener's World presenter will be on hand to launch the 5th annual show, which runs from June 22nd-24th at the Oxfordshire UNESCO World Heritage Site.

A multi award-winning gardener, Carol is a much-loved television personality whose own Glebe Cottage gardens were made famous in a six-part TV series and accompanying book.

As well as opening the show on the Friday, she will also be giving two talks over the weekend on her favourite plant-based subjects.

The Grand Floral Pavilion forms the centrepiece of the Show and features the UK's finest nurseries and growers giving expert advice and gardening ideas. It is guaranteed to be a riot of colour, fragrance and weird and wonderful plants.

A highlight for 2018 will be the brand new 'Orchid Tunnel' which leads into the Pavilion. Visitors will be able to walk through the tunnel and see over 1,000 orchids from all over the world.

With workshops, talks and demonstrations taking place throughout the event, you'll be guaranteed to learn something new and take inspiration for your own gardening project.

Visitors can also enjoy fabulous food and drink as well as an outdoor Plant Village and live entertainment throughout the weekend.

Visit the shopping village featuring over 250 stands selling everything from unique garden gazebos, greenhouses and arbours to beautiful flowers, gardening sundries and hundreds of other products.

The Home and Country Living Pavilion showcases a selection of original, handmade giftware, jewellery and luxury goods.

Enjoy fabulous samples and tastings at the Food and Drink Pavilion with a wonderful range of artisans and purveyors from Masons Gin, Truckle Cheese Sausages to Dips and Marinades – there will be something to tickle all taste buds!

Admission to the show includes entry to the Park and Gardens so visitors can also make a day of it exploring Blenheim Palace's Formal Gardens and 2,000 acres of 'Capability' Brown Parkland.
