Description
The China aster or Callistephus chinensis Garden Jewel Rose is a semi-dwarf variety that makes for excellent cut flowers. Its moderately early flowering features an abundance of flowers borne on sturdy, erect stems. Its flowers are reminiscent of chrysanthemum, are fair-sized and come in a superb shade of pink mixed with white. A real gem for the garden or for romantic bouquets, especially considering it has such a long vase life. These annual plants are easy to grow. Sow in a cold frame or directly in their final position, in a spot with good sun exposure and rich, well-drained soil.
China Aster, also known as Callistephus chinensis, is a Chinese annual plant of the family Asteraceae that has been cultivated since ancient times and that has produced and still produces, many varieties that are very interesting as bedding plants and as cut flowers. The plants of the Garden Jewel Rose variety reach a height of 50 cm in just a few months time, and are well-branched. Their stems carry oval, serrated, bright green leaves. Flowering takes place from July to September, featuring 8 to 8 cm, fully double floral heads that come in a pale pink shade that open to reveal an almost white centre. The central golden disk of the flower is barely visible.
The China aster is a first-rate bedding plant. Its flowers make for naïve but unforgettable scenes. A little out of fashion, they are still very decorative when planted in large drifts in flowerbeds since their flowers are perfect for pastoral bouquets, and they bloom for months if you take the time to remove their faded flowers. Sow them directly in the vegetable garden to obtain a profusion of blooms by the end of summer, even if they are just used to make bouquets. Among the wide range of existing varieties, there are some that carry flowers of various shapes that resemble those of Chrysanthemums with their fine, tapered petals arranged into pompoms that sometimes even have a ruffled look about them, or other varieties that present simple flowers like those of the type species. They come in many colours: from white to yellow, including all kinds of intense shades of pink and purple. The dwarf cultivars are perfect for borders and window-boxes, while the bigger, very double-flowered varieties are better for livening up the backdrop of your flowerbeds.

Planting and care
Sowing Chinese aster : These plants should never be sown in the same spot two years in a row. Sow outdoors from April to May and plant them out as soon as the plants have 2 to 4 leaves. Plant 40 cm apart, in a sunny spot with well loosened, moist, fertilized soil. Water frequently, but sparingly. It is a good idea to prick out the plants several times while maintaining their root balls, to encourage root development and to slow down the development of the stems, which otherwise could become leggy and break under the weight of the flowers. To obtain an earlier flowering, sow in a cold frame or in seed trays placed on a hotbed, from February to April. Sow the China aster in trays filled with sand and white peat, under cover at a temperature of 16° to 20 °C. Prick out in small individual pots when seedlings have at least four leaves. Place them in the garden when they reach a height of 15 cm. Plant stakes to support larger varieties with very double flowers. Sowing later, in June, allows for staggered flowering until late autumn and can be carried out directly in their final positions in the garden. These plants like neutral or slightly chalky, rich, well-drained soil and require a very sunny position. During dry weather periods, it is necessary to water the plants generously, two times a week, but care should be taken to water the plant and not the foliage, as China asters are susceptible to powdery mildew. Remember to remove faded flowers regularly throughout the season in order to prolong flowering and prevent the plant from weakening.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
