See text Ledum was a genus in the family Ericaceae, including eight species of evergreen shrub native to cool temperate and subarctic regions of the Northern Hemisphere and commonly known as Labrador tea.

Ledum species often grow together with poisonous plants such as bog-laurel and bog-rosemary, but certain species (e.g. L. groenlandicum and L. palustre) are easily distinguished by the distinctive rust coloured fuzz on the bottom of leaves.

Recent genetic evidence has shown that the species previously treated in this genus are correctly placed in the genus Rhododendron, where they are now treated as Rhododendron subsect.

[2] The species listed in genus Ledum (accepted and synonyms), with their current accepted names are: Ledum Rhododendron Other Natural hybrids (nothospecies) also occur.

Evergreen Labrador tea grows slowly, but retains its leaves year-round.
