The partnership between the Shropshire-based Boningale Nurseries and its green roof department GreenSky means landscape architects working on roof gardens can find specialist advice and all their planting stock in one place.
"This has proven to be extremely popular because many of our clients appreciate the ease of working with a single supplier that has the in-depth knowledge required to provide high-quality advice and planting options," said Frank Sandford, Boningale's sales and marketing director.
"Thanks to combining our expertise, roof gardens became one of our key growth areas in 2015 and we expect this trend to continue into 2016 and beyond."
He said that the decision for Boningale Nurseries and Boningale GreenSky, which are located in Albrighton, to work more closely together came after an increasing demand from landscape architects for advice on creating roof gardens, as part of their overall landscaping plans for both new building projects and for existing developments.
These have included herb projects where GreenSky was able to recommend the correct substrate for the nursery's rosemary and lavender, Greensky head Maggie Fennell added.
"By working more closely with the nursery, our combined expertise has enabled us to work with contractors who are trying to create as much useable green space as possible," Fennell explained. "Because we have a 'one-stop shop' for landscaping and green roofs, we can provide our semi-intensive SkyPlugs and substrates, plus intensive roof options using plants from our nursery. This has led to our clients winning more projects, too."
