| PACIFIC DOGWOOD (Cornus nuttallii) |
| Our West Coast native dogwood is the largest of all dogwoods, growing to heights of 30-50 ft. by 25 ft. wide. Large white flowers in spring have 4-8 false petals surrounding the true flowers, which are found in the yellow centers. Occasionally reblooming in early fall. Produces rosy red berries. Nice autumn foliage. Prefers shade and makes for a wonderful understory tree, white blossoms glow under dappled sunlight in the forest and shine in the moonlight. Attractive, flowering addition to a Pacific Northwest native planting. Native dogwoods are dying from dogwood anthracnose, a nonnative fungal disease that slowly kills the tree limb by limb. To minimalize chances for disease impact, grow only in ideal conditions; good drainage, deep soil that is high in organic matter, dry summers with no supplemental watering once established, avoid pruning or other stress. Bark and wood is traditionally important to indigenous people and used in the making of tools such as bows and arrows. Bark contains tannin which can be used in dyes. Small well rooted seedlings. Also called Western Dogwood, Mountain Dogwood, or California Dogwood. Hardy to -30°F. Zone 4-9. |
