At Trowell Garden Centre we have a fantastic range of British-grown quality heathers. When people mention heather, they are almost always talking about two different genera of plants: heaths and heathers. Although both belong to the Ericaceae family, they are botanically different and are divided into the Calluna genus and the Erica genus. For practical purposes, however, they are nearly identical, sharing colour, form, and growth habits. They are all evergreen, well-mannered, and low-maintenance plants that thrive in similar conditions of sunlight, water, and soil. Winter hardiness is the only major difference between species.
