❁ Lavender (H3) flowers, VIII–X; dark green foliage; neat habit; height 31–45cm; spread 46–60cm.
The history of double-flowered Calluna vulgaris is very complicated; William Curtis (Brompton, London, England) apparently had a plant as early as 1789. The name ‘Flore Pleno’ appears to have been first published in France in 1814.
Named from flos = flower; plenus = double. It is at least debatable that the name ‘Flore Pleno’ is not now properly applied.
