《Essential Reading for Rose Lovers》Series One
Compared to the content about roses that most people are familiar with, the "Essential Reading for Rose Lovers" Series One, the editor will introduce the following.
Roses belong to the Rosaceae family, Rosaceae. There are about 200 species of Rosaceae worldwide, with 82 species native to China. Modern roses now have about 20,000 species, and roses generally refer to the Rosaceae plants that can bloom continuously.
I. Roses can be divided into six categories based on their morphological structure:
1. Ground Cover Roses: Less than 30 cm in height.
2. Miniature Roses: Less than 30 cm in height.
3. Shrub Roses: Those below 50 cm are called dwarf shrub roses, and those above 50 cm are called shrub roses.
4. Tree-like Roses: Short 65 cm/Medium 90 cm/Tall 130 cm.
5. Columnar Roses: About 2 meters.
6. Climbing Roses: Over 2 meters.
II. Classification of rose varieties:
1. Hybrid Tea Roses, abbreviated as H.T.
Strong and beautiful in tree form, with glossy, leathery leaves. Stalks are hard and upright, with vigorous flowering ability. Most bloom singly, with large and full flowers. Cold-resistant with a long flowering period.
2. Floribunda Roses, abbreviated as FL
Strong growth with a vigorous (yellow varieties are slightly weaker) branching habit. Tree form is shorter or medium height, with slightly smaller leaves and thorns. Elegant shrub-like tree form, small flower diameter, clustering and blooming in large quantities. Cold and heat resistant.
3. Grandiflora Roses, abbreviated as GR
This series is bred from Hybrid Tea "Armstrong" and Floribunda "Fragrant Flower". Large and numerous flowers, continuously blooming in large quantities, lack of light purple varieties. Strong cold and disease resistance, with about 50 varieties worldwide by the early 1980s.
4. Climbing Roses, abbreviated as CL
Primarily divided into Climbing Roses and Climbing Shrubs.
5. Miniature Roses, abbreviated as Min
Compact plant form, not exceeding 30 cm, with fine and tough stems, small leaves, native to China.
6. Shrub Roses, abbreviated as SH
Strong and resilient, suitable for extensive management, cold-resistant, good disease resistance, lush growth, some varieties bloom once at the end of spring or beginning of summer, with a long flowering period, can be trained into columnar roses.
III. Tree-like roses consist of three parts:
The rootstock is usually dog rose or sparse-flowered rose; the trunk is thornless wild rose; the canopy is hybrid tea or floribunda rose. Tree-like roses need support, and the trunk should not be exposed to direct sunlight, otherwise the bark is prone to cracking and pest infestation. The canopy is not cold-resistant, and preventive measures are needed at minus 12 degrees Celsius in winter. The lifespan of roses is generally over 20 years. Plants used for cut flower production are usually renewed every 4 to 8 years. Under natural conditions, the lifespan can be very long.
Some foreign data, a European red rose in the Bois de Boulogne Park in Paris, France, is marked with the year "1900". A dog rose next to the Hilde Sheim Cathedral in Germany is at least several hundred years old. In 1885, a young double white Damask rose was moved from Scotland to Mrs. Burlin Devore's Garden in Arizona, USA. By 1973, this tree had a circumference of 1 meter, a diameter of 30 cm, and could accommodate more than 150 people under its canopy.
The giant rose (Rosa gigantea) growing in the Himalayas of China reaches a height of 15 meters, possibly the tallest rose in the world.
