Participate in this 'weed walk' and learn how to identify and gather some of the most common edible weeds and wild foods available in your garden and in other disturbed areas. Many gardeners are already recognizing many of the benefits of these 'interlopers.' However, when it comes to serving them up in the kitchen, few of us have learned to take full advantage of these labor-free gifts. This hands-on workshop at Discovery Park includes discussion on gathering ethics, local rules and regulations, safety, and general information about how to cook with weeds. Attendees receive a handy take-home flier with field identification information and cooking tips.

Join UW Botanic Gardens and Cascadia Forest Therapy for a unique forest bathing opportunity in the Washington Park Arboretum. Forest bathing (or shinrin-yoku) has been popular in Japan for decades and is gaining momentum in the US. The practice encourages you to move in nature at a slower pace and take in the atmosphere around you. Multiple scientific studies have shown that the practice lowers stress and blood pressure levels, while increasing immune system functioning, making you more resilient to diseases and illness.
During this class the guide, in partnership with the forest, will offer an evolving series of invitations crafted to help participants slow down and open their senses.

Cost: $35 for PlantAmnesty Members, $75 for non-members
REGISTER ONLINE, Limited financial aid slots offered on a first-come, first-serve basis.
Instances of mal-pruning and good intentions gone awry are sometimes explained away as “pruning art.” From improperly sheared hedges to ineffective design and training, this class will contrast examples of mal-pruning with bona-fide forms of pruning art and show how to use them to best effect. We’ll cover hedges and topiary, espalier, coppicing, pollarding, and pleaching, ending with a humorous note with slides from Cass Turnbull’s “The Good, The Bad, and the Bizarre” collection. Part of the Master Pruner Series held in partnership with PlantAmnesty.
