How to Choose Native Plants for Your Oregon Landscape?
When choosing native plants for your Oregon landscape, a few essential factors affect their success. First, it’s crucial to consider whether you’re in western or eastern Oregon since the climates differ between these regions.
You’ll experience warm and dry summers and wet winters in western Oregon. The native plants here are resilient enough to withstand the dry summer spells while benefiting from the rainy winters. On the other hand, eastern Oregon has colder winters with snowfall, and the plants in this region are well adapted to handle the lower temperatures.
Another important consideration is the amount of shade in your landscape. Some native species thrive in full sun, while others prefer partial or full-shade environments. Additionally, you’ll want to pay attention to the soil composition. Understanding your soil’s characteristics will help you choose plants that thrive in your specific conditions.
