Kalmia are mainly evergreen shrubs that are native to the North American continent. Kalmia angustifolia is also known in some places in the wild in Europe.
The genus includes nine species according to the latest botanical classification. It belongs to the scientific family Ericaceae.
Kalmia is named by Carl von Linné after the Finnish-Swedish botanist Pehr Kalm, who collected it in eastern North America.
Goal of the European Kalmia Society is to make the genus Kalmia more popular, support hybridizing, production and spreading of Kalmia species and cultivars.
Hybridizing of Kalmia cultivars is still a great challenge. The pollination is quite specific. Show the videoThis video shows how the flower releases the pollen immediately after the slightest touch. It was produced by Dipl.-Biol. Axel Hinnemann as scientific assistant and technical head of the Centre of Microscopy (Prof. Dr. Kerstin Koch) with the support of Prof. Dr. Peter Scholz (Vice- President for Research and Development)

At the same time we strongly urge that all new cultivars be thoroughly tested and evaluated before they are named and registered. Each new Kalmia that is offered to the public should be distinctly better or different from existing varieties.
Anyone who knows of cultivars that are not listed, or who can assist with further information about those that are, is requested to Please contact the Registrar by using the contact formcontact the Registrar.
