Meconopsis betonicifolia
Himalayan blue poppy is a cool‑summer perennial prized for clear blue flowers. It needs part shade, evenly moist but sharply drained, humus‑rich soil, and an acidic reaction. Plants are challenging where summers are hot or dry. Best performance in the Pacific Northwest, coastal Alaska, and other cool, moist summer climates. In less suitable areas it is often short‑lived. Plant among ferns and woodland perennials that like similar conditions.
