A short-lived yet vigorous perennial, 'Slieve Donard' boasts a basal rosette adorned with oval leaves covered in delicate white hairs. Come early to midsummer, its branching, bristly stems reach skyward, showcasing a cluster of pure sky blue poppies, each with overlapping petals and contrasting yellow stamens, measuring 10-16cm (4-6in) across. The decorative seed capsules, although covered in bristly hairs, hold no viable seeds. Ideal for woodland edges with reliable summer moisture, this sterile clone is known for its resilience, consistently presenting well-rounded flowers occasionally kissed by hints of purple or mauve. While this Himalayan Poppy may pose a challenge to cultivate, the allure of its ethereal blooms makes it a worthy endeavour for adventurous gardeners.


  • Garden care:
    Stake with bamboo canes or brushwood before the flowers appear. Deadhead regularly to prolong flowering. Apply a generous 5-7cm (2-3in) mulch of bark chippings, well-rotted leaf mould or composted pine needles around the base of the plant in spring.
