We could use your support...

The Arb needs your donations & memberships more than ever to keep the plants growing, the lights on & staff to maintain it all. Not only that, we have so many projects, programs, gardens and initiatives worthy of support, some of these are Milkweed for Monarchs, the Penstemon Collection, Summer Camp Scholarships, Environmental Education & more. Donating to our greatest needs allows us to use the funds where they are desperately needed. If one of our programs speaks to your heart, you can direct your donation there - just leave a note when you're checking out.

If you prefer, you can mail your donation to us at

4001 S. Woody Mountain Rd., Flagstaff, AZ 86005

A Gift in Your Will or Living Trust

Estate planning is among the most important things you can do for your loved ones (and causes). It is, however, a task many dread and put off dealing with until later in life. Most estate planners recommend establishing a plan sooner than later, and reviewing and, if necessary, updating that plan every five to ten years, or whenever you have a significant life event.

Adding a gift (also known as a charitable bequest) to your will or living trust is an excellent (and tax-efficient) way to make a lasting positive impact on your community, and it is much easier than you may think! So whether you are updating an existing plan or drafting your first, by including a gift to The Arb you are ensuring that we can continue our mission for years to come!
