If you live in the Pacific region, you know that seasons in your garden look different from the rest of North America. There are many potentially important factors and multiple systems for mapping zones in our region; ecoregions, microclimates, hardiness, rainfall, soil types, elevation, chill hours, ecology, water quality, minimum and maximum temperatures. You have likely observed that the Pacific Ocean annually influences weather patterns from the coasts to the mountains.

In an already complex region, climate scientists tell us that extreme changes are underway. In order to live in this new climate era, we seek to build our sense of place and deepen our understanding of where we are. What language should we use when we talk about these unique places? What tools can help us understand and define the Pacific region horticulturally? And most importantly, how does this help us garden?

In this episode of our Multi-Disciplinary Approaches to Resilient Landscapes series, you will hear directly from professionals who are behind the mapping resources you have likely used and some that may surprise you. We’ll get the inside story of what scientists consider when representing regional landscapes and what they think about the future we will all be part of.

Coming Soon

What Climate Is This? Part 2: Seeking Conclusions

To follow Part 1, we are inviting horticulture professionals from throughout the region for a panel discussion about how mapping and climate tools can help us understand and define the Pacific region horticulturally and most importantly, how they can help us garden.

Multi-Disciplinary Approaches to Resilient Landscapes

We are honoring multi-disciplinary innovators who are solving the climate and horticulture challenges of today. We begin this series by exploring new ideas in resilient garden design, juxtaposing designers who share similar climate or landscape conditions from geographically and culturally distant locations.
