David's Penstemon

Penstemon davidsonii

The Pacific Northwest is blessed with an incredible array of native plants which are great ornamentals for the garden. Because these plants have evolved in our wet-winter, dry summer climate, they are able to thrive in gardens that may be challenging for introduced or exotic species. It is still important to know the right environment for each native plant you plan to use in your garden; each native species has its preferred environmental niche. If you have soil that is very sandy and lean, choose drought tolerant species that prefer well drained soils and can tolerate drought. If your soil is heavy and tends to stay wet well into summer, choose plants that tolerate wet soil.

We’ve put together an abbreviated list of Pacific Northwest Natives with some very general information about what type of soils and sun exposures they prefer. Click on the links for more information about habitat and range.
