In 1997 they started exporting their seed to Walters Gardens in USA and Thompson & Morgan in England and in 1999, to Jelitto seeds in Germany. In 2009 their seedline, ‘Sweethearts’ was given the Award of Garden Merit from the Royal Horticultural Society in Wisley, England and in 2008 'Dusky Maidens' was awarded the International Perennial Plant of the Year by the International Perennial Plant Breeders Association. The success of their specialist breeding has since led to their hybrid delphinium seeds being exported to many different countries around the world.
In 2017 the business was sold to Katrina Hindmarsh, who is continuing with the breeding of specialist delphinium lines.
Dowdeswell’s Delphiniums remains committed to producing the best delphiniums in the world. New Millennium delphiniums are known for being reliable performers, strong stemmed, vibrant coloured and heat tolerant.
