Notes: Mexican Olive is a medium-sized evergreen shrub or small tree valued for its fragrant white flowers and ornamental appeal. It is often used in landscaping for its attractive appearance and ability to thrive in hot, dry conditions. Mexican Olive is a good choice for xeriscaping and adds visual interest throughout the year, especially with its late spring to summer blooms. While it can handle drought once established, it still benefits from occasional watering during extreme dry spells. Unfortunately, the fruit is not good to eat, but wildlife will enjoy it!
