Rhododendron hypoleucum
Labrador tea is a rhododendron! The Labrador teas (Ledum) were combined with the rhododendrons (Rhododendron) in 1990 on the basis of molecular studies. The Finnish researcher Harri Harmaja has re-named most of the known Labrador teas, including the native Finnish species, formerly Ledum palustre, now Rhododendron tomentosum. The Ledums hybridise with some Rhododendron species, which indicates their close relationship.
