Choosing Perennials for the Pacific Northwest
Native flowering plants are a good place to start when choosing perennials for northwestern U.S. Perennial flowers in this area have several advantages. They have acclimated to conditions domestic to this region such as the amount of rainfall and soil conditions. This means they are guaranteed to return reliably year after year, unlike more exotic subtropical perennial choices. However, many subtropical plants will not only survive year after year but thrive. This depends on which area of the northwest you reside in, of course. In some extremely mild areas, subtropicals will survive without any assistance, while in others protective measures should be taken during winter. When looking for perennial flowers suitable for the Pacific Northwest, know the conditions for your area. Is rainfall a rarity? If so, look for plants with drought tolerance. Are temperatures mild year-round, or are cold temperatures and snow the norm? Also, ask yourself what the job of the perennial will be, such as groundcover, privacy screen, or mass planting? What type of sun exposure will the perennials need?
