Home Info Native Shrubs of the Pacific and Northwest
Sierra Nevada mountain range

Plants of the West or Pacific coast vary from the hot arid South, North to Alaska and every point in between. The Pacific coast is long strip from the crest of the Sierra Nevada and Cascade ranges in the East, to the Pacific Ocean in the West. North, from the Alaska coastline all the way South to Baja, California.

This defined region embraces extremes in climate and length of growing seasons. What other region offers extreme winters and cold temperatures, to Mediterranean and sub tropical conditions.

In the dry South, Xeriscaping may be in order and plants may be from the desert southwest or natives that require less water and enjoy the heat. Plantings like Sages, Manzanita and Toyon.

As you head North, dry heat gives way to cooler temperatures and rain. Temperate rain forests follow the coastline from northern California, through Oregon, Washington, British Columbia and Alaska.

What is amazing about the region is many of the same shrubs that grow in California are native to coastal Alaska and Canada. Though summers are short in Alaska and Canada, the warmer Pacific waters keep the coastal temperatures at a moderate level where Hardiness zones 5 and 6 are the norm.

Though I will mention a handful of shrubs, many if not all of them can grow throughout most of the Pacific coast region and all are natives.

California coffeeberry (Rhamnus californica)
