Himalayan blue poppy 'Mrs Jebb'

'Mrs Jebb' is a short-lived perennial about 1m tall, forming a rosette of oval, hairy leaves suffused with red-purple when young. In summer, erect, leafy stems bear a cluster of deep clear blue poppies with slightly ruffled petals and contrasting yellow stamens. The seed capsules, covered in bristly hairs, are decorative but contain no viable seed
