Cornus is more commonly known as Dog Wood. They make great hedges which are easily grown. In the winter they have an added bonus of beautiful vibrant stem colours.
I look at the following types that we have grown into hedges at the Stackyard Nursery:
Cornus sanguinea or Common Dogwood is a medium to large deciduous shrub that can grow to 6 meters.
Cornus stolonifera ‘Flaviramea’ which is a medium sized shrub grown primarily for its winter stems. Clusters of white flowers in May and June and oval, dark green leaves, which redden in autumn and fall to reveal bright, yellow-olive winter stems. The stems of this dogwood look stunning planted alongside salmon-pink and red-stemmed varieties. An excellent specimen plant for sunny, moist areas of the garden.
Snakebark Maples are easily distinguished by their distinctive bark which on younger trees consists of vertical stripes. They originally come from Asia apart from one species which comes from eastern North America.
