Wildflowers of the Pacific Northwest
One of the most diverse regions of the country, both in climate and vegetation, is the Pacific Northwest. From mountain ranges and valleys to seacoasts and deserts, the vegetation of this area exhibits a great diversity of ecological habitats in response to variations in latitude, proximity to the ocean, rainfall, and temperature from east to west and north to south. Forests west of the Cascades, for instance, are moist coastal rainforests dominated by conifers, while forests east of the Cascades are more like the Rocky Mountains, with a mixture of conifers and deciduous trees. Woodland wildflowers, many of which are unique to this region, abound in the shady forests, while desert and grassland species thrive in the warm, dry conditions of the interior valleys. Coastal areas offer a completely different palette of wildflowers. This collection includes some of the most common wildflowers encountered in various habitats of the Pacific Northwest.scientific name | common name(s) | image gallery |
