  • circleLife cycle

    Cosmos bipinnatus 'Sensation Pinkie', commonly known as Cosmos, begins its life as a seed that, once sown in soil with adequate sunlight and warmth, typically germinates within 7-21 days. After sprouting, the seedling emerges with its first pair of true leaves and continues growing, developing a strong stem and a lacy foliage characteristic to cosmos. The plant then enters the vegetative stage, focusing on leaf and stem growth until it matures and is strong enough to support blossoms. As it enters the flowering stage, typically from midsummer to fall, pink blooms with yellow centers appear, attracting pollinators like bees and butterflies. After pollination, the flowers fade and seed heads form, containing seeds that will disperse to create new plants. The lifecycle can end with the first hard frost in colder climates as Cosmos bipinnatus 'Sensation Pinkie' is an annual, or it may resume from seeds in the following growing season.

      Spring-Early Summer

    • The garden cosmos, or more specifically the Cosmos bipinnatus 'Sensation Pinkie', is commonly propagated through seeds. The ideal time for sowing these seeds is either in early spring or directly after the last frost when the soil has warmed up to at least 60°F (15°C). To propagate, one can simply scatter the seeds over loose soil and lightly cover them with about 1/4 inch of soil. Keep the soil moist but not drenched until germination, which typically occurs within 7 to 14 days. Once seedlings have sprouted and reached a sufficient size, they can be thinned out or transplanted to their desired location in the garden, ensuring they have full sun exposure and well-draining soil for optimal growth.
