|Growing this exceptionally attractive blue-flowered poppy is no easy task, but for the collector, the effort is worthwhile when sky-blue petals begin to unfurl. Plant in early fall so that roots have time to establish. Excessive winter moisture in poorly drained soil is the kiss of death. The Meconopsis genus as a whole prefers cool, damp summers and humus-rich, acid soil. This is not the plant where summers are long, hot and dry. Best used in naturalized woodland or rocky-sloped drifts.
