Rose Species and Near Hybrids
Rose Species and Near Hybrids
Mostthat one sees, either in formal displays or in suburban gardens, are varieties based on fairly recently categorized types — hybrid tea, floribunda, miniature and so on. These varieties have beautiful form and colour and, most important, recurrent flowering — often throughout the season.
Species roses — descendants of wild roses growing in many parts of the world — have a charm and beauty all their own. Most of them flower only once a season, but many provide autumn colour in the form of hips. They are easy to cultivate, thriving in most well-drained soils that are not acid. Young plants may require some in the first few years to give them shape, especially those that produce hips. The best and hips develop on strong growths formed the previous year.
