Plant characteristics and classification of creeping dogwood
Plant order, origin and occurrence of creeping dogwood
The creeping dogwood (Cornus canadensis) occupies a special position within the dogwood genus: Unlike most other species, it is not a woody plant but a perennial. From a botanical point of view, however, it also belongs to the large dogwood family (Cornaceae). It is native to the deciduous and coniferous forests of North America, Greenland and Alaska, but can also be found in California and Japan. In the home garden it can be used as a versatile and above all varied ground cover plant.
Characteristics of creeping dogwood
Plant
As a perfect groundcover, the creeping dogwood grows only 10 to 20 centimeters (4 to 8 in) tall. It spreads rapidly by underground root runners and grows flat creeping.
Leaves
Depending on the weather, Canadian dwarf cornel is deciduous or evergreen – in mild regions, the latter is usually the case. The leaves are opposite and arranged in dense whorls at the shoot ends. Their shape is ovate to elongated oval, the leaf blade is crossed by two to three veins. In autumn, the foliage of the creeping dogwood takes on a bright orange-red color.
Blossoms
The flowers of the creeping dogwood appear from the end of May to the end of June. They consist of small greenish heads, each surrounded by four bright white bracts.
Fruit
In the fall, the Canadian dwarf cornel forms numerous bright red berry-like drupes. They stand together in small groups and form a nice contrast to the green foliage.
Creeping dogwood – cultivation and care
Location
The creeping dogwood grows best in partially shady places. The more light it gets, the more it needs to be watered.
Soil
In its natural habitats, the Canadian bunchberry grows on coniferous humus, deciduous or boggy soils. Similar conditions should also prevail at the planting site in the home garden. The perennial grows very well in moist, neutral to slightly acidic soil with a high humus content, but with as low a lime content as possible. It does not thrive in heavy, compacted soils. These must be deeply loosened and enriched with plenty of sand before planting.
Planting
For an area-wide planting you need 10 to 15 plants per square meter (10 sq ft). Carefully place the shallow roots in the ground. A good planting space between plants is about 15 centimeters (6 in).
Care
Creeping dogwood is very easy to care for. The only thing it can not do without is an adequate supply of water, its site is ideally always slightly moist. For watering make sure to use water with low lime content, such as rainwater. The perennial is sensitive to lime in all respects. When the creeping dogwood loses its foliage in the fall, you should leave it on the spot. On the one hand, it protects the root area from cold and dehydration, and on the other hand, nutrients are released when it rots, which are directly returned to the plant in this way.
Propagation
To propagate, you can divide the rootstocks of Cornus canadensis. In addition to rhizome division, sowing creeping dogwood is also possible. The best time for sowing is autumn, as the seed need cold to germn.
Diseases and pests
Creeping dogwood is relatively insensitive to plant diseases and pests. Occasionally, mealybugs or powdery mildew occur.
Wintering
Winter protection is not necessary, Cornus canadensis is absolutely frost hardy.
Use in the garden
As a ground cover, the creeping dogwood really lives up to its name. It forms a dense green carpet within a very short time and thus beautifies partially shady areas in the garden. Cornus canadensis grows particularly well under rhododendrons, with which it shares a preference for acidic soils. It can also be combined nicely with ferns and shade-tolerant grasses. Whether for underplanting, at the edges of a wood, or in the front of a bed, creeping dogwood is a versatile perennial for many different garden situations. One often sees the Canadian dwarf cornel in heather gardens or in gardens with many woody plants and trees.
