There are a wide range of Garden Centres and Nurseries that have heathers for sale both in store and online. The Garden Centres tend to stock only those heathers that are in flower at that time. Nurseries usually have a wider range of plants for sale throughout the year.
A good place to look for heathers is via the RHS Plant Finder. You should be able to find a nursery near you or online. Click here for Plant Finder.
There are also links to some specialist nurseries in our Nurseries section.
