Paluchowski will remain in an advisory role during February while Matthew Wilson takes up responsibility overseeing all departments at Clifton, comprising retail, design, landscaping and maintenance.
Wilson was curator of RHS Hyde Hall in Essex and curator and head of RHS Harlow Carr in Yorkshire. He will continue to advise The Landscape Agency as an associate, as Clifton Nurseries will be working closely with TLA on a range of future projects.
Clifton chairman Fabia Bromovsky said: "We are thrilled to welcome Matthew Wilson to Clifton. As well as a wealth of practical knowledge and expertise, he will, I know, bring vision, flair and inspirational leadership to our close knit team at Clifton".
Wilson said: "I’m delighted to be joining one of London’s much loved horticultural institutions and look forward to working with the team at Clifton to fulfil its potential for even greater growth and success. Being able to develop an ongoing relationship with TLA is a great opportunity for both businesses".
Landscape Agency MD Patrick James said: "I have thoroughly enjoyed working with Matthew and wish him well in his new post. I am pleased that he will continue to work with us as an associate, notably in the run up to 2011 Chelsea Flower Show where we are working on a show garden sponsored by the Royal Bank of Canada."
