The Climate Adapted Gardener
Presented by John Albers
Bellevue Botanical Garden, The Aaron Education Center and live-stream Zoom
Gardening in the Pacific Northwest now requires a wider range of strategies: drought-ready planting, stronger soils, smarter water use, and plant choices that hold their form and function through stress. In The Climate-Resilient Gardener, John J. Albers draws on decades of building and curating Vista Gardens to share practical, field-tested guidance on creating landscapes that thrive through changing conditions. The talk explores plant selection, soil and water fundamentals, and design principles that support biodiversity while preserving the layered beauty that perennial gardeners value—texture, structure, seasonal cadence, and longevity.
John J. Albers is the founder and curator of Vista Gardens, a nonprofit botanical garden in Bremerton, Washington. He began creating the garden in 1998 and helped establish the Albers Marcovina Vista Gardens Foundation in 2007. Over decades of hands-on work, John has developed an approach that blends horticultural craft with ecological function—favoring resilient plant communities, water-wise stewardship, and design that delivers structure and beauty across the seasons. He is the author of The Climate-Adapted Gardener: A Pacific Northwest Planting Guide, forthcoming in 2026.
For those attending in person, refreshments will be served starting at noon. Door prizes will be given away. A recording of the lecture will be available for registrants for 2 weeks following the event.
Join NPA for this event either in-person at Bellevue Botanical Garden or via Zoom. Please register to attend in-person or via Zoom. Walk-ins for non-registrants will be allowed up to venue seating capacity.

Recording will be available to members and registrants through March 28, 2026.

Plant Sale at Bellevue Botanical Garden
10 am to 1 pm
March is a great time to buy plants from a select group of local small nurseries and specialty growers who sell an amazing collection of hard-to-find and old-time favorite perennials, shrubs, ferns, grasses and more. Your support helps these growers thrive and prosper, and in return they can grow even more special plants for our gardens!
This is a 'Farmer's Market Style' plant sale where you purchase plants directly from each seller - bring your own small wagon/cart to carry your purchases back to your car. The plant sale features plants from local growers.
