Answer: Hyacinth bean (Dolichos) does grow in the Pacific Northwest, but because of the typically cool and rainy summer, it doesn't perform as well as Scarlet Runner Bean or Lonicera (honeysuckle). If you're looking for a temporary screen, plant scarlet runners. A more permanent solution (but not as fast!) would be honeysuckle. Both plants need at least half-day sunshine and well-draining soil.
