Roses have been grown in gardens for centuries and some of the ones still in existence are very old indeed. They are perhaps the most famous of all plants.
There are roses for all sorts of gardens: old fashioned ones, modern ones, romantic fragrant ones, climbers to cover walls or create bowers and ground cover varieties to create a floriferous carpeting. The only disadvantage of roses, is that they need a bit more looking after than most other plants.
Although some rose have attractive glossy foliage it is the flowers for which most people grow them. There is a wide range of colours, mainly based on white, red and yellow with all the colours between. There have been attempts to breed blue ones but the results are mainly mauve or lilac rather than blue. Scent is once more an important factor and many modern roses, especially the English Roses, have been bred with this in mind.
Some roses flower only once in the year, usually around mid summer. Other will flower then and have a lesser repeat flowering perhaps in the early autumn. Some flower non-stop from the summer through well into the autumn.
Roses will grow in most soils but prefer one that is reasonably rich in humus. Unfortunately most roses need pruning and there is a constant need to keep a watch out for various pests and diseases and treat them as necessary.
