Meconopsis are the Himalayan poppies, and the blue-flowered species are among the most coveted and most exacting plants in cultivation. The flowers are large, silky and translucent, held on tall bristly stems above rosettes of hairy, often bronze-tinted leaves, and the pure sky blue of the finest forms is unmatched by anything else hardy. Not all are blue - there are excellent yellow and red species too - and the genus includes both reliable perennials and monocarpic kinds that flower once and die.
