The Falkirk-based business will expand its hospitality offerings, following the model used to refresh its Mayfield Garden Centre in Kelso.
The £48.5m turnover business is seeking planning permission for the expansion of Mortonhall Garden Centre in Edinburgh, which will include an extension to the shop, a large new restaurant and new outdoor plant area. It will also progress redevelopments in Stokesley and Leeds and it has potential redevelopment plans for two further stores in Polmont and Northwich. The renovations will help to increase turnover to £50m within two years, says Klondyke.
Klondyke chief executive Bob Hewitt said: "We are now taking the opportunity to capitalise on recent successes that have led to strong turnover growth.
"The support from HSBC will enable us to fulfil our ambitions and invest funds back into the business.
"Plants are our passion and we will always stay true to the quality of our products.
"However, we want to evolve Klondyke sites from traditional garden centres into social places for people to meet friends and family."
Doug Baikie, head of large corporate for HSBC in Scotland, added: "Klondyke Group’s model for growth has proved to be a success and we are very proud to be backing its plans for the future.
"Their sites are transforming into full-service retail operations but are still rooted in the company’s traditional passion for gardening.
"We want to lend more to Scottish businesses to help them achieve their ambitions and our SME fund is making it easier and cheaper for businesses to borrow."
