Pacific Dogwood Cornus nuttallii
ABOUT
The plant commonly known as the Pacific dogwood is a beautiful and distinctive species that stands out for its impressive display of flowers and foliage. This plant's most striking feature is its large, showy bracts—often mistaken for petals—which are typically white or sometimes tinged with pink, creating a star-like surround for the smaller, inconspicuous greenish-yellow flowers at their center. These bracts bloom in the spring and often reappear in a less dramatic fashion in the late summer to early autumn. The leaves of the Pacific dogwood are simple and opposite, providing a lush background of green throughout the growing season. They are oval to ovate in shape, coming to a point at the tip, and showcase prominent veins that curve gracefully toward the leaf's margins. In the fall, the foliage transforms into vibrant shades of red to purple, adding a dramatic flare to the landscape before the leaves drop. Adding to its year-round appeal, the Pacific dogwood bears red berry-like fruits after the flowering season. These fruits are technically drupes, which means they have a fleshy body and a hard stone enclosing the seed. They provide a source of food for birds and other wildlife during the fall and winter months. The bark of the Pacific dogwood is gray to brown and develops a textured, furrowed appearance as the plant ages. During the winter, when the branches are bare, the elegantly tiered branching structure of the Pacific dogwood is revealed, offering visual interest even in the dormant season. This graceful branching pattern also makes the plant a popular choice for landscaping year-round interest.

WaterThe Pacific Dogwood should be watered deeply once a week during dry spells to maintain even moisture, which is particularly important during the first few years to establish a strong root system. The amount of water typically needed is around 1 to 1.5 gallons per watering for young trees, and for mature trees, it may require up to 5 gallons depending on the size and conditions. Make sure the soil is well-draining to prevent waterlogging. During the winter, you can reduce watering as the plant's water requirements diminish. Adjust the watering schedule based on rainfall, and always check the soil moisture level before watering.
LightThe Pacific Dogwood thrives best in a spot with dappled sunlight or partial shade. It can tolerate full sun in cooler climates, but in hotter areas, protection from intense afternoon sun is necessary to prevent leaf scorch. Ideally, position the tree where it receives morning light and shade during the hottest part of the day.
TemperaturePacific Dogwoods prefer a temperate climate and are hardy in USDA zones 7 through 9. They can tolerate a minimum winter temperature down to about 0 degrees Fahrenheit and a maximum summer temperature around 95 degrees Fahrenheit. The ideal growing temperatures range between 60 and 75 degrees Fahrenheit for optimal growth and flower production.
PruningPruning the Pacific Dogwood is important for maintaining its shape and promoting healthy growth. It should be pruned in late winter or early spring before new growth begins. Remove any dead, damaged or diseased branches, as well as any crossing or rubbing branches to enhance air circulation. Thinning out the canopy can also improve light exposure. Pruning should be done selectively to maintain a natural appearance and done every 2 to 3 years.
CleaningAs needed
SoilPacific Dogwood thrives best in a well-draining, loamy soil that is rich in organic matter. A good mix could be equal parts garden soil, compost, and coarse sand or perlite. The soil pH should be slightly acidic to neutral, ranging from 5.5 to 7.
RepottingPacific Dogwoods, which are typically grown outdoors and not in containers, rarely need repotting. However, if grown in a pot, repot every 2-3 years to refresh the soil and accommodate root growth.
Humidity & MistingPacific Dogwood prefers moderate humidity levels but is adaptable. Strive for a humidity level of around 40-60% for optimal health and growth, as is common in its natural forested habitats.
Suitable locationsIndoor
Place Pacific Dogwood by a bright window, away from hot radiators.
Outdoor
Plant Pacific Dogwood in partial shade, protect from strong winds.

Life cyclePacific Dogwood (Cornus nuttallii) begins its life cycle when seeds disperse from mature fruit, usually aided by birds. Seedlings emerge in moist, fertile soil, often in partial shade beneath forest canopies. As the plant grows, it develops into a small to medium-sized deciduous tree, with a distinctive horizontal branching pattern and oval-shaped leaves. In spring to early summer, the tree produces showy white to pinkish bracts surrounding small flowers, which are pollinated by insects. Following pollination, flowers develop into red berry-like drupes that mature in late summer to fall, providing food for wildlife and completing the reproductive cycle. Throughout its life, Pacific Dogwood experiences periods of dormancy during winter before resuming growth in the spring.
PropogationPropogation time
Spring to early summer
The Pacific Dogwood (Cornus nuttallii) can be propagated through various methods, however, softwood cuttings are a popular way of propagation. The best time to take softwood cuttings is in late spring or early summer when new growth is still flexible and not yet hardened. To propagate by this method, a gardener would cut a 5 to 6-inch (12 to 15 centimeters) piece of softwood from the Pacific Dogwood, making sure that there are at least two sets of leaves on the cutting. The lower leaves are removed, and the cut end is dipped in a rooting hormone to stimulate root development. The cutting is then placed in a well-draining soil mix, ensuring that at least one set of leaves is above the soil level. It's crucial to maintain high humidity around the cutting, often achieved by covering the pot with a plastic bag, and to keep the soil moist but not waterlogged. With proper care, roots typically develop within a few weeks.
