Cosmos ‘Fizzy’ is a vibrant, fluted-petal cosmos series known for its semi-double to double blooms with beautifully ruffled, cupped “fizzy” petals. Flowers come in a charming range of colours—rose, pink, white, blush, and soft bicolour—each bloom resembling a delicate pinwheel with layered texture.

The series is adored by cut flower growers for its strong stems, excellent vase life, and its ability to add dimension and movement to arrangements. Plants bloom continuously from mid-summer until frost, attracting butterflies and beneficial pollinators to the garden.
