Heather (Calluna vulgaris) begins to flower in September and is a source of luscious late summer colour, the campaign said.
"Heather is a European classic and is native to the coastal areas of Western Europe, Great Britain and Ireland, as well as being one of Scotland’s most prolific plants.
"It grows in beautiful long shoots with shingled leaves and small symmetrical flowers. Its purple and pink flowers have a slightly weathered appearance and that gives both the plants and the countryside a tough and natural look. In the garden, the plants provide a hardy carpet that give a calm and authentic effect whilst in pots, heather becomes a robust eye-catcher."
