We are now using Active Network to manage our program registrations and fee payments. The registration links embedded in the programs listed below will take you directly to the site where you can register for programs and pay fees using your credit card or debit card.

Be advised that after you have completed your registration and made your payment, you will see a pop-up window that will tell you about Active Advantage, which is a membership service that you may subscribe to that gives you discounts on some programs in Active Network and other benefits. This is only activated if you verify your email by entering it in the box and click on the Accept button. Your card will be charged for the Active Advantage membership if you enter your email address and click the Accept button. You do NOT have to be a member to register for arboretum programs, and if you don't want to become a member of Active Network, simply ignore this pop-up window.

Washington Youth Garden

Do you have a group of kids that needs to get outdoors for some great garden learning experience? A SPROUT Field Trip will do just that. Depending on the season, we might pick a strawberry, harvest asparagus, or taste some juicy cherry tomatoes in our fruit and vegetable production area. We also maintain a large herb garden, compost area, and several educational theme gardens, like the sunflower house, that change annually—so there's plenty to explore! There are a lot of slots open during the summer. Fee: 50-100% of Participants Eligible for Free or Reduced Price School Meals $100; 0-50% of Participants Eligible for Free or Reduced Price School Meals $200. Registration Required.
