Landscape trees are woody plants cultivated in urban, suburban, and designed outdoor environments for aesthetic, ecological, and functional purposes. Studying these trees is important for plant science because it bridges horticultural management with ecology, informing how species selection, soil conditions, and environmental stressors affect tree health, growth, and resilience in non-natural settings. Research in this area supports urban forestry efforts by identifying which species and cultivation practices best sustain tree vitality and ecosystem services in human-modified landscapes.

Both red maple and Freeman maple leaves are toxic to horses, but Freeman maple — a popular landscaping hybrid — caused roughly 65% more blood cell damage in lab tests than red maple. Horse owners and property managers near pastures should treat Freeman maple as an equal or greater hazard than red maple.
Freeman maple leaf extracts produced 64% more methemoglobin and 67% more hemolysis than red maple extracts in horse blood cell tests (n=120 horses).
Barn location (site) was the largest single factor explaining differences in blood cell oxidation between individual horses, outweighing age, breed, and body condition.
Regression models explained 22–89% of variation, with age and time of sample collection as minor additional contributors for red maple, while only barn site remained significant for Freeman maple.
