Qu'est-ce que cornus alternifolia ?

Cornus alternifolia, also known as alternate-leaved dogwood or pagoda dogwood, is a deciduous tree that is native to eastern North America. It is a member of the Cornaceae family and is often grown for its attractive foliage and flowers.

The alternate-leaved dogwood typically grows to a height of 15-30 feet (4.5-9 meters) and has a spread of 20-35 feet (6-10 meters) when fully mature. It has a unique branching habit, with branches that grow horizontally in a tiered or pagoda-like manner. This distinctive growth pattern gives rise to its common name "pagoda dogwood."

One of the most striking features of Cornus alternifolia is its foliage. The leaves are oval-shaped and alternate on the branches, hence the botanical name "alternifolia." In spring, the leaves emerge with a deep green color, which turns to reddish-purple in fall for a beautiful autumn display. The leaves are followed by small clusters of white flowers that bloom in late spring or early summer. These flowers give way to dark blue fruits, which are loved by birds and other wildlife.

Cornus alternifolia prefers moist, well-drained soils and can tolerate both sun and shade. It is often used in landscaping as an ornamental tree due to its unique shape and colorful foliage. In addition, it can be grown as a shrub or trained into a multi-stemmed tree form.

This dogwood species is also valued for its ecological importance. The flowers attract pollinators, such as bees and butterflies, and the fruits provide an important food source for birds. Furthermore, the tree offers nesting sites and shelter for various bird species.

In terms of care, Cornus alternifolia is relatively low maintenance. It benefits from regular watering, especially during dry periods, and can benefit from a layer of mulch to help retain moisture. Pruning may be done in late winter or early spring to maintain its shape and remove any dead or damaged branches.

Overall, Cornus alternifolia is a beautiful and unique tree native to eastern North America. Its distinctive growth habit, attractive foliage, and ecological benefits make it a popular choice for gardens, parks, and natural areas.
