Britain’s Queen Elizabeth II has described her historic State visit to Ireland as a ‘brilliant’ experience.

The trip last week was hailed as a phenomenal success and the royal even hinted she may return to the country.

During a tour of the prestigious Chelsea Flower Show she revealed her thoughts to Irish gardener Diarmuid Gavin, who created one of the more outlandish exhibits - a floating garden pod.

The television gardener was stopped by the Queen soon after she was presented with the Queen Elizabeth II orchid - the only one of its kind - grown in her honour by a Taiwanese team of gardeners.

Gavin said he joked with the monarch during their chat, adding: ‘I said to the Queen, 'thank you for coming to Ireland and as a reward I brought my garden over'. She said, 'I had a brilliant time'.’

Talking about his garden he added: ‘The garden is inspired by Ireland so it's very, very green and inspired by fantasy films like Avatar and Edward Scissorhands.

‘You go wandering along a path onto a Willy Wonka-style garden that lifts you up into the sky.’

The Queen was joined during the preview of the Chelsea Flower Show by other royals including the Duke of Edinburgh, the Duchess of Cornwall, the Duke of York, Princess Beatrice, the Earl and Countess of Wessex and Prince Albert of Monaco, who was involved in a exhibit inspired by his home principality.
