Summer of sweet peas

This year we’re celebrating the centenary of Arthur Cobb’s sweet pea trails by trialling hundreds of different cultivars of sweet pea in our beds and borders.

Arthur Cobb was Dyffryn’s Head Gardener from 1908 to 1919. From 1913-14 the gardens were filled with thousands of varieties of dahlia as part of growing trials in conjunction with the RHS.

With Reginald Cory, Arthur led on these trials and gained a reputation for his skills in plant cultivation. This reputation secured him a new job with Reading University where he was tasked with trialling a multitude of sweet peas for the RHS.

Dyffryn has a strong history of experimentation and plantsmanship. We are emulating this legacy across the gardens in coming years and our summer of sweet peas is just the beginning.

The sweet peas will begin to flower in late May and last through until early September. We’ve chosen a broad host of sweet peas to show off the breadth of species, colours, shapes and scent. We’ll also be growing the only Welsh named variety Gwawr Cymru (Welsh Dawn). It features a white background with a pink blush.

Don’t miss the Annual Garden display which will feature tunnels of sweet peas in 72 different varieties. More can be found on the South Terrace, Kitchen Garden and the Herbaceous Border.

Our garden team have been working hard germinating hundreds of sweet peas behind the scenes. Each chosen for its beauty in scent, form, colour and growth type.

A small sample of sweet peas we will be growing include:

Heritage varieties

  • Cupani (1695)
  • Painted Lady (1752)
  • Purple Prince (1896)
  • Miss Willmott (1901)

  • Hannah Dale
  • Emily

The flowering season will take place from late May to September, visit across the summer to see the whole range blooming in a rainbow of colour.

We have been working in partnership with the National Sweet Pea Society who have given us Gwawr Cymru seeds and assisted this display.  You can find out more on their work here.
