Euonymus microphylla, also known as Littleleaf Euonymus, is a compact evergreen shrub that thrives in Tucson’s arid climate, offering year-round greenery and subtle elegance. With its small, glossy leaves, this shrub has a tidy, dense growth habit, making it ideal for borders, low hedges, or as a ground cover. It adapts well to full sun to partial shade and prefers well-drained soil, though it is quite tolerant of dry conditions once established. During the cooler months, Euonymus microphylla maintains its rich green color, adding a touch of consistency to desert landscapes. It is drought-tolerant but benefits from occasional watering during extended dry spells, especially in the winter. Cold-hardy to around 20°F, it can endure Tucson's mild winters but may need protection during severe cold snaps. Light pruning in late winter helps keep its shape neat and promotes healthy growth. Euonymus microphylla is an excellent choice for low-maintenance, water-wise gardens, providing reliable greenery throughout the year.
