Cosmos 'Fizzy Pink' seeds can be sown outdoors in a sunny spot after the last frost, typically from March to June. They prefer well-drained soil and are ideal for balconies, containers, or garden beds where they can flourish with minimal care.
Sow the cosmos bipinnatus seeds about 3mm deep in a small tray filled with compost, then cover with a clear container and keep in a warm place such as a windowsill to encourage germination.
Once seedlings appear, thin them to avoid overcrowding and pot on to allow room for growth, ensuring they have enough space to reach their mature size suitable for a 30 cm pot or garden bed. Harden off plants before planting outside in late May or June for best results.
Water the plants moderately, allowing the soil to dry out slightly between watering to prevent root issues. Deadhead spent blooms regularly to encourage continuous flowering and maintain their delicate pale pink appearance throughout the growing months.

An easy annual that thrives in sun, Cosmos bipinnatus ‘Fizzy Pink’ gives tall stems of soft pink flowers for cutting, borders and pots — and it’s reliably pollinator-friendly.

The name 'cosmos' derives from the Greek word for order and harmony, reflecting the flower’s perfectly symmetrical heads. Spanish priests historically cultivated these flowers on mission grounds, appreciating their balanced beauty.
