How to Grow Cornus common name Dogwood.
Dogwoods are a lovely group of deciduous shrubs with delicate variegated foliage but the high point of interest is the Autumn and Winter Colour.
A really easy to grow shrub with a preference for sun for the best colour, but tolerant of many conditions Cornus will thrive in damp soil which make an ideal shrub for a difficult spot for planting streamside or alongside a pond in damp soil. Dogwoods are really tough. The image left shows a bunch of whips which are very small immature shrubs which are often sold quite cheaply as opposed to buying a mature pot grown shrub. If you want to plant a group of shrubs say 10 or so it is worth looking at whips, obviously they take longer to mature, but if you dont mind a couple of years or so this can be an economical way of mass planting.
There was no immediate spot to plant the Dogwood, so they were temporarily put into a tug and unfortunately forgotten. Remembered some months later and as you can see no worse for wear, and better than that the Dogwoods are 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.
Cornus need no real attention; plant and they will grow. To keep the stems in really good colour, Dogwoods do best if cut back almost to the ground in March of each year as in the image left. it looks savage at the time but they quickly grow back. It also means you have a clump of lovely red coloured peas stick /small plant supports for the coming growing season.
Cornus alba 'Sibirica' grows up to 2-2.5 m tall, another very popular varieties is Cornus sericea 'Flaviramea' which produces bright yellow stems.
Although Cornus are grown for their strong Winter colour which does look lovely in the winter gloom it is easy to overlook the fact that the shrub has very attractive variegated foliage which looks good with other shrubs. In the image below left the Cornus, which is on the right of the image, is planted with Cotinus Coggygria 'Royal Purple' to great effect, and was planted like this in a supermarket car park but looked just great. Cotinus is another easy to grow lovely shrub which grows quite large, advise on how to grow Cotinus and images.
