Summer highlights at Plas Newydd

Enjoy the sights of summer at Plas Newydd, with roses in bloom on the Cool Border, accompanied by nepeta, which is loved by the bees. The Terraces and Borders surrounding the House are full of colour.

On the Hot Border, the alstroemerias have started to flower and will continue all summer long. Marigolds and salvias are soaking up the heat, with the dahlias coming into bloom. Around the House, blue geranium ‘Brookside’ and salvia ‘East Friesland’ are magnets for the bees.

Make the most of the summer evenings in the garden at Plas Newydd with extended opening until 8pm on Wednesdays during school holidays between 23 July and 27 August 2025.

Terraces

This area of the terraces has a sheltered, sunny microclimate, so a planting scheme was drawn up inspired by Mediterranean regions around the world, such as South Africa and California. The borders were planted up at the beginning of June - African daisies and Californian poppies are already in bloom, with salvia, angels’ fishing rods and agapanthus to come.

Rhododendron Garden

The secluded and peaceful Rhododendron Garden was planted in the 1930s with specimens recently introduced to the UK by plant collectors. It was then expanded by the 7th Marquess in the 1940s with wedding gifts of rhododendrons from Lord Aberconway at Bodnant.

Alongside these venerable specimens you'll also find some stunning magnolias. The early blooming brings large splashes of welcome colour to the garden after the winter.
