Akene Seeds - Alternate-leaf Dogwood

To successfully sow your seeds,
see the growing notes at the bottom of the page!

The alternate-leaf dogwood (Cornus alternifolia) is a large shrub or small tree of the Cornaceae family, generally reaching 4 to 6 m in height. It is distinguished by its tiered habit: its branches spread horizontally, forming superimposed layers that give it an elegant appearance. The leaves, simple and oval, have arched veins and are arranged alternately, unlike most other dogwoods. They turn beautiful golden yellow hues in the fall.

In spring, around late May or early June, the plant produces large, flattened corymbs of small, fragrant, nectar-rich creamy white flowers. These flowers are followed in late summer by clusters of dark blue, almost black berries, borne on reddish peduncles that create a decorative contrast. The grayish-brown bark becomes slightly striated with age.

The alternate-leaf dogwood grows in open forests, forest edges, ravines, and riverbanks, preferring moist to fresh soils rich in organic matter and well-drained. It tolerates partial shade and full sun, but flowering is more abundant in sunny exposure. In Quebec, it is found in the south and center of the province, where it plays an important ornamental and ecological role. 

Furthermore, native dogwoods (Cornus spp.) are recognized as keystone plants for biodiversity in many North American ecoregions, as they support a great diversity of insects and birds that use their flowers, leaves, and fruits.

Ecological roles
The alternate-leaf dogwood provides nectar and pollen to many pollinators, including bees, hoverflies, and butterflies, in early summer. Its fruits are an important food source for several bird species, such as robins, thrushes, and waxwings, which help disperse the seeds. The plant also provides refuge for small wildlife and stabilizes soils along waterways or on gentle slopes.

Alternate-leaf dogwood seeds must undergo scarification and cold stratification to ensure germination. See the growing notes below for more details.
