February 23, 2018, 7pm —FREE LECTURE: "Botanical Gardens and Environmental Education: An Exchange between the Pacific Northwest and Eastern Russia," Tony Allison

A remarkable initiative began in 2009, with the simple idea that the Russian Far East and the Pacific Northwest have much in common, and that botanic gardens in the two regions had much to teach each other. From that simple idea, a thriving foreign exchange program has developed between environmental educators in Seattle, Vladivostok, Sakhalin, and Irkutsk. Join us for this fascinating lecture, led by project initiator and Seattle native, Tony Allison, who will be joined by two of his colleagues from the Russian Far East. Tony will explore three Russian botanic gardens, their surrounding native floras, and their growing environmental education programs. Please join us for this rare opportunity to see inside this unique, people-to-people exchange and discover the gardens and flora of the Russian Far East.

FREE, but please register
Doors open at 6:15pm.

Did you know that there are thousands of kinds of bees? Wild hole-nesting bees, like our friendly mason and leafcutter bees, are efficient pollinators. They are looking for nesting habitat, and bee hotels are fast becoming a backyard staple. In this family class, appropriate for adults and children, you will learn how hole-nesting bees live, what they need in your garden to thrive, and how to provide them with a 5-star bee hotel. Your class fee includes nesting hole materials and the Native Bee Guide (26-page reference booklet) for you to take home. Bring your own clean, recycled, lightweight material for building the protective bee hotel, such as a half-gallon milk carton, family size soup can, or large coffee can. It can be anything you like, as long as it is about 7 to 8 inches deep and is easy to install on a garden wall or fence.

Pre-registration required.
Limited to 20 adults. Each adult can bring a maximum of 2 children. One bee house and book per registration.

March 15, 2018, 10am-12pm, "Garden d'Lights Orientation," Taught by Garden d'Lights Volunteers

Ever wondered what goes on behind the scenes at Garden d’Lights? How are those critters and light displays built? And what does it take to install and repair them? Well, here's your chance! Join the Garden d’Lights team at a FREE orientation where we will answer these questions, demonstrate our techniques, and more. You’ll view partially constructed lights, then join a small group that will work with a member of the Garden d’Lights build team who will show you how the features are built. Everyone will be able to bunch lights onto a rod and use a cable tie to anchor them in place. We will also show you how we repair lights—those of you with an electrical or woodworking background will be interested to see the tools and techniques. Unfortunately, you will not be able to leave with the results, but you are welcome to join the team as it starts to prepare for the 2018 Garden d’Lights season!

Limited to 75 individuals, aged 16 or older
(younger kids okay, if accompanied by adult).
