Pernettya mucronata ‘Rubra’

Extra notes and interesting information:

Tops need pruning to stay attractive.
According to Oregon State University, the “genus Pernettya was designated by a French botanist, Charles Gaudichaud-Baeupe, in 1825 to honor Antoine J. Pernetty, author of Bougianville’s voyage to South America. 

The genus Gaultheria was created earlier in 1735 by C. Linnaeus to honor Dr. Gaultier, a physician of Quebec City. Some 200 years later in a review of the 2 genera, several hybrids of Gaultheria and Pernettya were described, however, the authors did not suggest uniting the 2 genera, believing that more study was needed.  In 1990 a thorough study of the 2 genera was published and the authors concluded that Pernettya should not be maintained as a separate genus.  This has resulted in Pernettya being merged into Gaultheria.  However, in the nursery trade, the Pernettya designation is still frequently used.”
