  • circleLife cycle

    Cosmos, specifically the Cosmos bipinnatus 'Apollo Pink', begins its life cycle as a seed sown in well-draining soil after the last frost in spring. The seeds germinate within 7 to 10 days in warm soil, emerging as seedlings with a pair of true leaves after the initial cotyledons. As the plant grows, it develops a sturdy stem and a feathery foliage characteristic of the cosmos. Following the vegetative stage, the cosmos enters the flowering stage, typically blooming in summer or early fall, showcasing its vibrant pink petals around a central disc. After pollination by insects, the plant sets seeds within the flower heads that dry on the plant. Eventually, the plant completes its annual life cycle, dying with the first hard frost, but often self-seeding to generate new plants for the next season.

    • Propogation time

      Spring to Summer

    • Propogation: Cosmos bipinnatus 'Apollo Pink', commonly known as Cosmos, is most commonly propagated through seeds as it is a fast-growing annual. The best time to sow Cosmos seeds is after the last frost in spring when the soil has warmed up. To propagate Cosmos by seeds, simply scatter the seeds lightly on top of a well-draining soil mix and lightly cover them with a thin layer of soil, no more than 1/8 inch (about 3 mm) deep. The seeds typically germinate in 7 to 10 days in temperatures between 70-85 degrees Fahrenheit (approx. 21-29 degrees Celsius). Watering should be done gently to keep the soil moist until germination occurs. Once the seedlings are large enough to handle and have developed a couple of true leaves, they can be thinned out or transplanted to their final growing positions, ensuring they are spaced about 12 inches (30 cm) apart to allow for adequate air circulation and growth.
