Plants that Need Extra Love
Some plants are hard to establish & need extra care.
But, we love them anyways.
This article addresses plants that are more difficult to establish in restoration settings. It is part of our Species Selection Guide where we share select collections of plants based on their ecosystem services, site condition needs, or material type.
Which Plants Need Extra Love?
Some of our favorite Pacific Northwest natives are difficult to establish in restoration sites. This article seeks not to dissuade you from installing these beauties in your landscape, only to better prepare you for facilitating their success!
These plants often grow abundantly in forests or on roadsides, but for various reasons don’t take well to transplanting into harsh sites. Most of these species require mature soils or shade as they settle in (also see our shade list) and are best suited for enhancement plantings.
Unless otherwise stated, all plant information comes from our Species Descriptions, where we invite you to read about more plants native to our Pacific Northwest.
