As it's name suggests, this is one of the first blueberries to produce. It also thrives in the Pacific Northwest, according to Oregon State University Extension's website. The berries Earliblue produces are large and considered sweet and dessert-appropriate. For best results, this cultivar needs well-draining soil, protected from frost. It will grow about 5 feet tall and wide, and produces white or pink flowers in the spring.
Washington State University Extension's website recommends Patriot as one of the best choices for the Pacific Northwest. This upright bush produces large yields of big, early berries. Unlike Earliblue, however, Patriot is a cold-hardy cultivar and doesn't mind soil that is a little soggy. It grows about 4 to 6 feet tall and 4 to 5 feet wide, and produces white flowers in the spring.
This vigorous early- to mid-season producer is extremely fast growing. According to Yummy Northwest's website, Bluejay grows twice as fast as other blueberries popular in the Pacific Northwest. Like all blueberries, it wants acidic soil, and grows best when that soil drains well. Bluejay is both winter hardy and drought tolerant, and grows 5 to 7 feet tall and just as wide. It produces white flowers in the spring.
This cultivar is the most popular blueberry in the world, according to the Washington State University Extension website, which also recommends it for the Pacific Northwest. It grows large, light-blue berries in great quantities. The bush reaches up to 5 feet tall and wide, and offers pink or white flowers in the spring.
This mid-season blueberry cultivar produces sweet fruit that's among the lightest blue blueberries available, according to Yummy Northwest, which advises growing this bush in well-draining, acidic soil. Chippewa grows to about 4 feet tall and wide. It's extremely tolerant of cold Pacific Northwest winters, and grows white flowers in the spring.
For parts of the Pacific Northwest south of Puget Sound, Oregon State University Extension's website recommends Elliott, a cultivar with a mild-tasting berry. This bush produces fruit late in the season and offers medium production. Elliott grows 8 to 10 feet tall and white flowers in the spring. Unlike many blueberry bushes, however, Elliott doesn't offer colorful fall foliage.
