Double-flowered common heather

Calluna vulgaris (L.) Hull

Double-floweredness in common heather is a genetically fixed varietal ornamental trait that determines the presence of additional petals in the flower. It is a qualitative parameter that distinguishes ornamental cultivars from wild forms.

In the reference 9 varieties crop Common heather, where this is mentioned in the description.

In common heather, this trait is expressed by an increase in the number of petal-like parts, which gives the inflorescences a dense and full appearance. Double-floweredness is not a pathology or a result of viral infection, but rather a target breeding trait inherent in specific cultivars, such as 'Annabel', 'County Wicklow', and 'Dark Beauty'.

From an agronomic perspective, double-floweredness is evaluated exclusively visually as a qualitative parameter. An important feature of such cultivars is the reduction of their value as honey plants: the specific structure of double flowers often limits the access of pollinating insects to the nectar, which must be taken into account when planning landscape plantings.
