This week I’m speaking to Philip Johnson of Johnson’s Sweet Peas. Philip grows and sells plants and seeds via his website and he sells and exhibits his plants at shows across the country, when they’re on! He judges at major shows and has put in 25 years service as a Sweet Pea judge. He is a former chairman of the National Sweet Pea Society/RHS Sweet Pea trials held at Wisley and is currently serving as a member of the RHS Herbaceous Committee. So what Philip doesn’t know abut sweet peas you could write on the back of a stamp and still have room to lick it.
