80-100+ year old Saguaros in front of Joshua-tree
The Saguaro, pronounced sah-wah’-ro, is the state flower of Arizona (sorry it’s not in bloom, yet) and is protected by law. It grows up to 50 feet tall, but very slowly, and the oldest plants could be 150-200 years old.
Joshua-tree, the largest of the yuccas at 15-30 feet tall, is iconic to the national park bearing its name in southern California. It also grows in abundance in Joshua Forest Parkway in western Arizona, not far from where I live. Mormon pioneers during the late 1800s named this species Joshua because its shape mimics a person with uplifted arms gesturing wildly as if to pray.
Here’s another interesting discovery.
Ocotillo, pronounced o-ko-tee’-yo, grows multi-stems up to 30 feet tall. Leaves appear only after rain then withers as the soil dries. The tip of each stem displays a vibrant red cluster of flowers. This cycle repeats several times during the year.
OK, now you know we’re in the desert, so steer clear of these.
Prickly Pear Cactus is one of the most common cacti found in the desert.
