Grandiflora sweet peas to grow
We pick some of the best grandiflora sweet peas to grow, including heirloom and modern varieties.
Grandiflora sweet peas were created when Henry Eckford, a Scottish horticulturalist, selected certain strains for their larger than average flowers and better general performance, then bred them.
The more recent, modern grandiflora varieties combine the strong fragrance and colourful blooms of the original, heirloom grandifloras with the large flowers and long, straight stems of Spencer-type sweet peas. They make wonderful, exuberant cut flowers for the house.
