Description
Cosmos sulphureus Polidor is a variety of annual Cosmos with semi-double flowers, in vibrant colours ranging from lemon yellow to red, passing through orange. Its early flowering is very long, making it perfect for countryside gardens and for making country bouquets.
The Polidor variety has a medium-sized habit, reaching a height of 75 cm (30in) and spreading over 45 cm (18in). It is a very interesting Cosmos for flowering around the house or adding a touch of warmth to a flower bed. You can associate it with other annuals, such as Coreopsis Be Bop or Pavot Cherry Glow for a vibrant effect.
Originating from South America and belonging to the Asteraceae family, Cosmos sulphureus is a fast-growing annual plant that can reach 1.5 metres (5 feet) in its natural environment. It has a branching habit, with finely cut foliage (slightly less than Cosmos bipinnatus) in light green, and displays a tireless flowering from June to the first frosts.
Cosmos sulphureus Polidor is easy to cultivate. Its flowering is foolproof: poor soil, heat, humidity... Give it sun and, no matter what, it will flower.
It is a particularly melliferous plant, and if you refrain from doing a major autumn clean-up, you will certainly have the chance to admire birds (especially goldfinches) come to peck at the last seeds.

Planting and care
Sow Cosmos seeds from March to May, at a depth of 3mm (0.1in), in fine soil and cover the seeds with a very light sprinkle of vermiculite. Place the seed tray in a mini-greenhouse at a temperature of 18-25°C (64.4-77°F) or wrap it in a polyethylene bag. Keep the soil moist but not waterlogged.
Light promotes germination, which occurs 7 to 15 days after sowing. When the seedlings are large enough to handle, transplant them into individual pots with a diameter of 7cm (3in).
Cultivate them in cooler conditions until the plants are sufficiently developed to be planted outdoors. When all risk of frost has passed, gradually acclimatise the plants to outdoor conditions for 7 to 10 days.
Plant them in full sun, in moist, well-drained soil, spaced 45cm (18in) apart. Pinch the tips of the shoots on each stem during transplantation to encourage branching and the production of numerous flowers.
Cosmos prefer a soil pH between 6 and 8.5, corresponding to the soil in their native habitat, the alkaline regions of Central America. They prefer full sun but tolerate partial shade. These plants are drought-tolerant once established, they are not prone to diseases but can be targeted by aphids. Spontaneous seedlings are common but not always true to type, without becoming invasive.

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.
