|Could you please tell me how to care for this perennial, what are its requirements and is it hardy in zone 5?
|Papaver alpinum is a perennial poppy, hardy from Zones 2-9. Plant yours in full sunshine in average to poor, well-draining soil. The plants require excellent drainage. You can achieve this by digging an 18" deep planting hole, adding a layer of gravel, then mixing some compost in with native soil, to fill the planting hole about half way. Then put more soil in, and plant the poppy, gently tamping the soil around the roots. Water well after planting, then water only during the hottest summer months. Disbud after blooming, and stake the plant if it's in a windy area. When frost kills back the foliage, cut it from the plant then mulch well to help protect the roots during winter. Remove the mulch in the spring as the soil warms and sprouts begin to grow. Poppies do not need to be fertilized, and do not like to be moved once they've become established.
