The vehicles travelled through Walsden, Littleborough, Rochdale, Ripponden, Smithy Bridge, Halifax, Mytholmroyd, Hebden Bridge and Todmorden.
Gordon Rigg Garden Centre was started by Gordon Rigg in Walsden, Lancashire, on 24 August 1945, with a £150 loan to buy two greenhouses, two cabins and a shed with garden tools.
He started growing plants and had a stall in Todmorden Market Hall.
Peter Rigg joined the business in 1968 and helped develop the business.
In 1988, they took over a garden centre at Kingsway, Rochdale.
Gordon Rigg died in July 2004 aged 84.
Gordon Rigg Garden Centre now employs over 180 staff both at Todmorden and Rochdale and is run by Peter Rigg and his wife Pauline.
Peter Rigg said: "Today customers come from all over the North of England and keen gardeners will travel from across the UK to visit us. People are continually surprised by our vast product range and the size of our garden centres. This is particularly true at Walsden which covers a huge floorplan and often people can spend up to half a day with us shopping and enjoying lunch in our café.
"The catering side of the business is continually growing and this was enhanced greatly when we opened a highly successful bistro at our Rochdale centre. Another area where we are currently investing heavily is in our online presence. We’ve recently launched our fully redeveloped mobile friendly e-commerce site that we’re continually developing and this has the potential to become another big growth area for us over the next couple of years which is hugely exciting."
