Meconopsis is a genus of flowering plants in family Papaveraceae, comprising about 40 species. It is an annual, biennial or perennial herbaceous plant, bearing spring or summer flowers.
Meconopsis cambrica (Welsh Poppy) is a perennial plant, native to south-western England, Wales, Ireland and western Europe. It grows well in damp, shady places on rocky ground, and soil that is on the acid side of neutral. The flower comes in appealing yellow or orange with four petals, and hairy green sepals that falls off quickly after the flower opens. It is self-seeds and can be invasive, spreading easily from the numerous small black seeds that produced in the summer.
Meconopsis grandis (Blue Poppy) is a clump-forming perennial, producing blue-purple flowers in summer. It is also the national flower of Bhutan.
Meconopsis aculeata is a perennial prickly plant, native to specific areas of Pakistan and India, in the west Himalayaa. It bears dark purplish blue flowers and is highly valued as a medicinal plant, which due to over-collection has placed it as an endangered species.
Meconopsis betonicifolia (Meconopsis Baileyi, Himalayan Blue Poppy) is a perennial plant producing large, bright blue flowers in early summer.
Plant Meconopsis in partial shade, in fertile, moisture-retentive but well-drained, neutral to acid soil. Propagation is by seed in spring and division after flowering. Slugs, snails and downy mildew can affect the growth of Meconopsis.
