This type of Dogwoods are really tough. The image below left shows a bunch of Cornus whips, which are small immature shrubs sold more cheaply as opposed to a mature pot grown shrub. If you want to plant a group of shrubs, say 10 or more, from the cost perspective it is worth looking at whips. Obviously they take longer to mature, but if you don't mind waiting a couple of years or so this can be an economical way of mass planting.
When these whips were purchased there was no immediate spot for the plants, so they were temporarily housed in a tug with some soil and then, unfortunately, forgotten about. Here they are some months later and as you can see from the image, none worse for wear. In fact, the whips were doing quite well in the tug, growing, supporting new spring leaves and were then happily planted out into a damp boggy area of the garden where they continue to do well as shown in the large image above.
The prunings are decorative and can be used as small plant /pea shoot supports, as shown here with some Bamboo prunings .
