They’re one of his horticultural passions and the quality of the produce he – well, produces – at the nursery is testament to that fact. Cameron pairs time-honoured horticultural traditions alongside the very best modern techniques in our fabulous, purpose-built nursery in Evesham. With a background that saw him place at the Grand Finals at the Young Horticultural Awards back in 2022, we’re proud to have someone that really knows his onions.
