• Cosmos 'Bright Light Mix' (botanically classified under Cosmos sulphureus, commonly known as Sulfur or Klondike Cosmos) is a popular, warm-season annual variety celebrated for its high heat tolerance and intensely vibrant, fiery-toned blossoms.

 Key Variety Profile

• Color Composition: Displays a radiant blend of fully open, semi-double, and double daisy-shaped flowers in shades of golden yellow, brilliant orange, and scarlet red.
• Growth & Structure: Grows as an airy, well-branched upright plant reaching heights of 60 to 90 cm (2 to 3 feet). It features attractive, deeply cut, fern-like green foliage that is distinct from standard pink/white cosmos varieties (Cosmos bipinnatus).
• Blooms: Produces a profusion of flowers spanning 5 to 7 cm across repeatedly from mid-summer until the first frost of winter.

 Cultivation & Sowing Guidelines

• Sowing Window: Flourishes in the warm season. Sowing is ideal when night temperatures stabilize between 25°C to 30°C (primarily late spring to early summer).
• Sunlight & Soil: Requires full, direct sun. It thrives incredibly well in poor, sandy, or moderately dry soils; highly fertile soils or heavy nitrogen fertilizers should be avoided as they prompt excessive foliage growth instead of flower production.
• Germination: Seedlings emerge quickly within 5 to 7 days from sowing, with flowers appearing approximately 50 to 60 days later.

 Garden Benefits & Landscape Uses

• Pollinator Magnet: An exceptional plant for attracting honeybees, butterflies, and other beneficial garden predators.
• Low Maintenance: Very drought-resistant and requires minimal watering once fully established in the soil bed.
• Mass Displays: Highly recommended for creating vibrant cottage garden backdrops, borders, and long-lasting cut-flower vase arrangements.
