Cosmos 'Cupcake Series' Overview

Cosmos 'Cupcake Series' are beautiful bushy annual flowers in white, pale pink and pink shades. These extra-large semi-double cup-shaped flowers can be between 90cm and 120cm above feathery mid-green foliage. Unlike other cosmos, they have fused petals that form an unusual bowl shape around their yellow centres. These low maintenance plants will produce flowers from midsummer until frost hits in autumn. These delicate looking flowers make lovely additions to floral arrangements with the bonus that cutting and deadheading will promote additional flower production. Botanically known as Cosmos bipinnatus (Cupcake Series), these plants are part of the Royal Horticultural Society “Plants for Pollinators” initiative to showcase plants that support pollinator populations providing ample amounts of nectar and/ or pollen. A great choice for encouraging pollinating insect wildlife into your garden!
