This cultivar of a native meadow coneflower has white, daisy-like flowers from early summer into early autumn. Its prominent, coppery-green, central cones are surrounded by large white ray petals that reach 4.5 inches long. 

White Swan is a compact perennial of upright growth, with solitary, white flower-heads with dull yellow central disks

 

When the flowers first appear the disk is flattened occasionally concave, but as the flowering progresses it becomes conical in shape. The brown fruiting heads are conical, chaffy, stiff and wiry.

The nectar is enjoyed by butterflies and its seeds are a favourite food source for small birds such as goldfinches. Plant in a rock garden, butterfly garden, or naturalise in a prairie meadow.

 

Hardy Perennial

 

An improved strain of this popular American wildflower! These superb coneflowers form low growing clumps of leaves from which the sturdy flower stems launch upwards with their large, rose-pink daisies. Unlike many varieties, the petals of Echinacea purpurea 'Primadonna' radiate outwards instead of downwards from a deep orange-brown central cone. With a compact, branching habit, this fabulous variety makes a lovely addition to borders and wildlife gardens where it will attract butterflies and other pollinating insects. Height: 85cm (33"). Spread: 45cm (18").
