Common Trees in Phoenix, Arizona
Phoenix, Arizona, boasts a diverse urban forest despite its desert climate. Several tree species thrive in the heat, providing shade, beauty, and contributing to a more livable environment. These trees are adapted to the arid conditions and provide vital benefits to the city.
Adaptable Arizona Trees
Many of the trees you’ll see in Phoenix have evolved or been carefully selected to cope with limited water, intense sun, and alkaline soil. Some notable examples include Palo Verde trees, Mesquite trees, and various types of citrus.
Palo Verde Trees
Palo Verde trees, meaning “green stick” in Spanish, are iconic desert trees. Their green bark allows them to photosynthesize even when they lose their leaves during drought. They produce vibrant yellow flowers in the spring. The Foothills Palo Verde (Parkinsonia microphylla) and the Desert Museum Palo Verde (a hybrid) are especially popular. They are drought-tolerant and provide excellent shade.
Mesquite Trees
Mesquite trees are another desert staple. They are known for their deep roots, which allow them to access groundwater. They produce edible beans and are nitrogen fixers, enriching the soil. Velvet Mesquite (Prosopis velutina) is common in the area, but thornless varieties are often preferred for urban landscapes due to ease of maintenance. They can be quite messy with leaf and bean drop, but offer good shade.
Citrus Trees
While requiring more water than native desert trees, citrus trees are a beloved feature of Phoenix gardens. Orange, lemon, and grapefruit trees add fragrance and beauty to the landscape, and of course, provide delicious fruit. Regular watering and fertilization are essential for their health. Mulching will keep roots moist, reducing water requirements.
Other Common Trees
Other trees frequently seen in Phoenix include:
- Tipu Tree (Tipuana tipu): A fast-growing, deciduous tree with bright orange-yellow flowers.
- Chinese Pistache (Pistacia chinensis): Known for its vibrant fall color, adding a splash of red and orange to the desert landscape.
- Mediterranean Fan Palm (Chamaerops humilis): A slow-growing palm that provides a tropical touch. More information can be found on Wikipedia’s page on Mediterranean Fan Palms.
