The University of Arizona Campus Arboretum boasts trees and unique plants from arid climates around the world. Seasonal cues such as soil temperature, rainfall, or the presence of pollinators will induce flowering. At any time of year, there might be lusty tropical clusters, aromatic scents from desert species, golden pannicles of pollen, red hot floret spikes, or white night-blooming bat-luring blossoms. Come visit the campus - or take a VIRTUAL TOUR to catch the blooms from other seasons.
