Hardiness
Assigning a rating for the frost hardiness of our plants is far from an exact science as each of them are along way from their native conditions. But based on their known tolerances we have created a system in which to help you decide which plants are most appropriate for your location.
The chart below shows the United Kingdom broken down into a series of zones. The intention here is to provide you with an idea as to which zones each of our plants will find most acceptable. You will see each plant's description comes with a series of icons, some, shown below on the left, offer information regarding growth habit. The other colour icons in the plant description relate to zones on the chart which are considered acceptable to that plant.
You can help the frost hardiness of your plants by making sure their soil is free draining, and also by mulching to insulate the roots in winter. But if you are in doubt, you can always plant into containers, which allows you to bring your plants in during the winter months.
