We use three different coloured labels to give you an instant indication of a plant’s frost hardiness. These are outlined below, but please note that they are a rough guide only. We are always on hand to offer advice on individual specimens.

If you are in any doubt at all about the requirement of the plants indicated with the traffic light system please do not hesitate to call us or contact us here:
