Description

A floral seashell in every bloom. ‘Sea Shells’ cosmos displays fluted, tubular petals that curl gently like ocean shells, unfurling in shades of pink, rose, magenta, and white. The unique petal form catches light and shadow beautifully, creating a soft, romantic movement across the garden.

Plants grow 3–4 feet tall, branching freely and blooming abundantly from midsummer to frost. Ideal for cut flowers, pollinator borders, and wildflower meadows, each stem holds multiple blossoms that last long in a vase.

First introduced in the 1950s, this variety remains beloved for its whimsical charm and carefree elegance—an heirloom that turns every garden bed into a sea of color and grace.
