The (dare I say it) edible, tasteless fruit of Gaultheria mucronata provide a mass of lilac-coloured blueberry-sized globes lasting throughout the winter in the Pacific Northwest of North America.
Various texts claim that fruit of all members of the genus Gaultheria can be toxic, but it is known that the indigenous peoples of Chile relied upon Gaultheria mucronata as a food source. I’ve eaten it without ill effect, though not for the taste. Rather, I find the sensation of popping the thick-skinned fruit a bit of a novelty.
Often known as pernettya, and less commonly as prickly heath, for many years this plant was placed in the genus Pernettya. This lasted until it was recognized that all members of the genus Pernettya were genetically indistinguishable from Gaultheria. As I mentioned in a previous entry, modern taxonomy suggests that nomenclature should reflect evolutionary relationships, so the names of all Pernettya species were changed in accordance with the evidence, and transferred to Gaultheria.
