Cosmos Seashells are amazing. Beautiful and elegant and yet so easy to grow and versatile.  These seashell lovelies have pastel-hued fluted petals, each resembling a dainty seashell.

Cosmos makes a wonderful cut flower, they are one of the most productive cut flowers you can grow and have gorgeous ferny foliage. They last well in a vase and the bees and other pollinating insects find them irresistible.
