In Yunnan and Sichuan, the highly-fractured landscape is home to the greatest concentration of species and forms of wild roses on the planet. From antiquity, comely forms of Rosa chinensis and Rosa gigantea were selected for propagation around homes and temples. Centuries of further selection and hybridization yielded more sumptuous blooms, in more colors, and borne on plants from dwarves to giants.
The first introductions to Europe of China Roses were ‘Slater’s Crimson China’ (1792) and ‘Parson’s Pink China’ (1793). These are still grown and admired in sunny climes where limestone forms the bedrock.
On of the great horticultural mysteries that perplexes gardeners in central Texas is the longevity of shrub roses in country cemeteries and around the decayed ruins of old homes, as opposed to the short and disease-ridden life of newly-purchased modern roses. A rose is a rose is a rose. Right? Unfortunately not.
The indestructible heirloom roses passed from generation to generation in San Antonio, Austin and the adjacent Hill Country are usually derived from species originating in the limestone hills of central China. They are propagated from cuttings and grown on their own roots.
Their sickly kin have invariably been propagated by grafting or budding onto a convenient rootstock. Convenient for the propagator, that is. The mass-produced grafted or budded roses from the West Coast or east Texas are given a rootstock that thrives in well-drained, sandy soils of acidic reaction. Inconveniently for us, our soils have poor internal drainage due to a high clay content and are alkaline in reaction.
