Plum trees have many environmental benefits besides their aesthetic appeal. They act as a food source for pollinators like bees, provide soil erosion prevention, reduce CO2 levels to ameliorate air quality and produce fruit that feed wildlife or can be made into jams. Plum trees require little maintenance and adaptation to arid and Mediterranean San Francisco's climate. This makes them an eco-friendly choice for city landscaping and encourages biodiversity in an urban environment. Show more
