Chilean guava is a great evergreen shrub for every landscape. It is beautiful in every season having both red and green leaves with reddish stalks most times of the year. The small berries harvested in the fall are amaizing, somewhat like an intense strawberry in flavor. This is also a great shrub for use in hedges.
