Native to the high plains of Mexico, Cosmos bipinnatus was carried across oceans by Spanish missionaries in the late 18th century, who admired the perfect symmetry of its petals and named it after the Greek word for harmony. It thrives where others might struggle—lean soils, full sun, and just enough rain to keep its airy stems upright. Its finely cut, feathery leaves and tall, willowy growth can reach up to two meters, creating a meadow-like softness. Blooming in shades of pink, purple, and white, it attracts bees, butterflies, and birds, becoming a living ecosystem through summer and autumn. Left to self-seed, it will return year after year, weaving itself naturally into the landscape.

germination
If you choose to sow the seeds directly outdoors, scatter them on the soil surface and lightly press them into the soil. If starting indoors, sow the seeds in individual pots or trays filled with seed-starting mix.
maintenance
mulching: Applying a layer of organic mulch around the base of the plants can help retain soil moisture, suppress weed growth, and regulate soil temperature.
deadheading: To encourage continuous blooming, remove spent flowers (deadhead) regularly. Further this helps preventing the plant from selfseeding and redirect its energy into producing more flowers.
fertilization: If you notice slow growth or pale foliage over the plant , you can apply a balanced, water-soluble fertilizer. Herefore follow the manufacturer‘s instructions.
flower harvest
Deadhead the fully developed flowers regularly to increase continuous blooming, leading to more dye matter within one blooming cycle as well as preventing self-seeding. Therefore, place two fingers below the flower crown and apply soft pressure upwards till the flower snaps off close to the stem. Use the flowers right away or place them onto a paper towel to dry before storing.
