Product Description

Mr Fothergills Cosmos Double Dutch White Seeds (Cosmos bipinnatus) are a refined and reliable choice for gardeners seeking classic elegance with minimal effort. This variety produces abundant, fully double and semi-double blooms in crisp white, creating a bright and airy effect that works beautifully in both traditional and contemporary garden designs. The tall, upright plants develop a well-branched, bushy habit, providing excellent structure in mixed borders.

Cosmos Double Dutch White is particularly valued as a cut flower, with long stems and blooms that hold well in arrangements.
