Meet Cameron
Putting shrubs in the starlight (and boy do they shine…)
Cameron is mad about plants, which is lucky, really, because he’s absolutely surrounded by them here at the nursery. Having studied at the Student Plant Unit at Pershore College, Cameron went on to compete at the Grand Finals for the 2022 Horticulturist of the Year Awards. With a team of dedicated growers on hand to help, Cameron utilises our industry-leading nursery (and the lovely, fertile conditions of the Cotswolds) to grow shrubs that aren’t just good-looking, they’re good-growing too.
