Mary Meyer

Palm trees have a long history in metro Phoenix. They are an iconic part of the landscape but are not native and consume considerable amounts of water. They have been planted for agricultural purposes, like date palms, and to accentuate landscapes and resorts. Palms can be tricky to identify and can hybridize with one another! There are nine verifiable species of palm trees in metro Phoenix on iNaturalist, can you find more?

Palm Tree Ecoquest

Palm tree fact: Arizona is said to have ONE native palm tree, the California fan palm (Washingtonia filifera). The single population grows in the Kofa National Wildlife Refuge and is thought to have been started from seeds in bird or animal droppings.

If you see palm trees pruned like this, please know this is not a good pruning practice! Palm trees rely heavily on their fronds to make energy and typically make a few fronds at a time. Some only make one or two fronds a year! Removing living fronds can slow or stop a palm’s growth. Over-pruning palms also makes them less storm tolerant. Don’t use climbing spikes to prune them. Climbing spikes, which do not close, wound the palm tree, inviting insects and pests. If you must, only remove dead or discolored fronds, never living fronds. Do not remove fronds that have a horizontal or upward orientation.

Observing palm trees in metro Phoenix can help us understand their population and distribution, and we can potentially learn about their water use in our desert city.
