John Longstaff has propagated a new penstemon variety called H E Bates which is being sold to raise money for Cancer Research from his Addington Road home.
The flowers, along with others John has grown, will be available to buy from this weekend.
John has been selling flowers to raise cash for the charity for more than 10 years.
He has raised several thousand pounds in that time.
To buy some of the flowers visit his home in Addington Road, Irthlingborough, or call him on 01933 650335.
The flower pictured is called Strawberries and Cream.
