Plants to celebrate garden’s centenary in the Great Pavilion

Rare rhododendrons bred at Exbury Gardens will be on show at RHS Chelsea for the first time.

They will appear on the Millais Nurseries exhibit in the Great Pavilion, marking the centenary of the Hampshire gardens and a joint conservation project to safeguard rare Exbury hybrids.

The banker Lionel de Rothschild created the gardens in 1919, spending 20 years developing the 200-acre woodland paradise.

More than 1,000 hybrids have been raised at Exbury and the horticultural team has been working with Millais Nurseries to conserve some of the rarer and more highly threatened rhododendrons.

The RHS Chelsea exhibit will aim to evoke the spirit of Exbury with rhododendrons, a miniature working railway and ticket office.

Both Lionel de Rothschild and his great grand-daughter, Marie-Louise Agius have won Gold Medals at RHS Chelsea.

Millais Nurseries has gained four consecutive Gold Medals in recent years.
