Meconopsis ‘Branklyn’
A very fine, very rare, reliably perennial, big blue poppy, almost lost to cultivation. Large rich-blue flowers in May. Moist, humus-rich soil in part shade, unless you live in the cool, rainy north, where you can grow it in full sun. Best blue in acid soil, though it is tolerant of more alkalinity if humus rich. Height 90cm.
