Meconopsis x sheldonii Lingholm

blue poppy

Unusual deep blue flowers

Perhaps one of the most desirable of all perennial plants, this is a real treasure for any garden. From a rosette of soft green leaves, covered with brownish hairs, the tall flower stems rise 75cm (30ins), topped with fat buds carried on a crooked neck. The stems straighten in early summer as the buds burst to reveal large, four petalled, intensely blue flowers filled with golden stamens. Unlike other varieties of blue poppy, this one is reliably perennial and produces fertile seeds.


Plant in dappled shade in beds and borders under deciduous trees. A woodland garden is ideal.


Needs acid soil, rich in organic matter that is never too dry or waterlogged. Cut back flower stem after blooming in first year. After that plants may be allowed to seed and old stems can be cut back in winter.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
