About your plant

Your shrub will be sent directly from our trusted grower, based in the heart of England. This means that you’ll receive a nursery fresh plant which was on the growing table one day, and at your door the following. Our expert nursery has spent decades perfecting the art of watering, feeding, and pruning shrubs, and will do so until hours before they are packed.


Your shrubs will be expertly packaged into a specially designed, extra thick cardboard box, which will hold it securely in place. Your plant will then be delivered via a delicate courier network to prevent any chance of damage in transit.
