Low maintenance, evergreen, and tasty bits of guava fruit! Picked too early, these berries had a sweet but "pine flavor," only the deep red ones have the strawberry guava-like sweetness I was hoping to add to my breakfast last fall (Fall 2021 update: picked when ripe and loving it). Regardless of my impatience, this evergreen shrub is worthy for its form (with occasional shaping), deep green foliage, and the reward of petite white flowers in the spring followed by the pea-sized fruit. The Chilean guava is slow growing and low maintenance, which to the avid gardener, means care can be redirected elsewhere while reaping the reward of its fruit. Our specimen is thriving in our rocky, alluvial soil with average watering, but it may be receiving too much shade despite prolific fruiting. I can see this shrub as a hardy, less care intensive substitution for blueberry shrubs, as one idea.
