Product Description
Mr Fothergill’s Cosmos Seashells Mixed (Cosmos bipinnatus) is a truly distinctive cosmos variety, prized for its unusual petal shape that forms charming, fluted “seashell” flowers. The tall, open plants produce masses of blooms in a lively mix of soft and vibrant colours, creating a light, natural look in borders, beds and containers. Flowering freely throughout summer and into autumn, these cosmos are both low maintenance and highly rewarding. Their open centres and long-lasting blooms make them a favourite with pollinators, while their strong stems also suit cutting for indoor arrangements.
