This blooming cactus may look like a saguaro, but it`s actually a cardón!
You may be wondering... if they look so similar, how can you tell the difference? Here`s some things to keep in mind:
🌵Cardóns are MUCH larger than saguaros. They have thicker trunks and can grow taller than 60 ft! 🌵They typically have more branches that form closer to the ground. 🌵They`re mostly found in Mexico whereas saguaros are primarily in Arizona.
Even though their blooms are short lived, the cardón remains a beautiful presence year round.
It`s almost that time of year when the Arboretum transforms into a beautiful autumnal display! Typically, fall colors start appearing here around mid-November or early December. It largely depends on weather patterns and temperatures. When it finally happens, pomegranates, canyon hackberries, willows, pecans, and our famous grove of scarlet-orange Chinese pistache will (most likely) be at their peak color, as will the cottonwoods in Queen Creek Canyon. It`s a sight you don`t want to miss!
Follow our stories closely for updates! We`ll make sure you know when the first fall colors start to appear.
When`s the last time you paused to watch a butterfly? 🦋 In a world that moves so fast, there`s something so calming and magical about noticing the small, beautiful things in your path.
Capture this feeling by joining one of our Butterfly Walks! You`ll learn about commonly found species and their host plants with a butterfly expert from Central Arizona Butterfly Association.

🍄Did you know that fungi are more closely related to people than plants? They may look like plants, but the way they grow, get nutrients, and evolve is completely different.
Fungi DO interact with plants. They grow by absorbing nutrients from organic material, which is why you often find them on dying trees, logs, or on ground level.
These little guys can be found on the fence surrounding Drover`s Woolshed. Next time you visit, keep an eye out for them and any other mushrooms in your path. Sometimes they pop up in places where you`d least expect!
These beautiful photos were taken by Tim Lee, one of our loyal members! We love seeing our visitors` photography. (Especially when they include cute birds! 🐦)
Want to see some of these birds for yourself? Join us for a Bird Walk! You`ll be surrounded by other avian enthusiasts helping spot and identify our little flying friends.
