Gaultheria insana (sym Pernettya furens, G. furens)

This has had its fair share of names but we love this current iteration as it perfectly describes the condition resulting from eating the berries "Mental confusion, madness and permanent insanity". At least we would have an excuse. We've safely grown this for many years with no ill effects although our staff might disagree. White flowers, pinkish fruit. Enjoy the flowers, don't eat the fruit. Likes plenty of moisture in a draining peaty, organic soil and best in light to part shade. Not the hardiest plant as it is coastal to low elevations in Chile but good in zone 9 or as a container plant which is what we do.
