Iris and peonies blooming

Featured Collection - Iris and Peonies

UPDATE June 21: Iris are still looking lovely! This ephemeral collection is past peak, but there is still lots of incredible colour throughout the garden. Peonies are at peak bloom, with hundreds of big, colourful flowers. This weekend will likely be your last chance to catch both these colourful collections.

Join us for a Iris and Peony Celebration!

Seasonal Bloom Times

Bloom time is often influenced by many natural events including temperature and climate. As these can vary from year to year bloom times are influenced by these factors. Below you will find ‘average’ bloom times for a number of RBG’s collections but please bear in mind that if we experience an early or late spring, bloom times could shift up to 10 days earlier or 10 days later.
