Very rapid spreading, very tall perennial native to China and Japan.
Plants are good for the backs of large borders and specimen plantings only, because of their size ( up to 10x8 feet or 3,00x2,50m ) and potentially invasive rhizomes.
BUT used in the right setting; the Plume Poppies are SPECTACULAR!!!
The handsome, deeply-lobed foliage is very large, to 20 inches / 50 cm wide. The leaves are blue-green above and whitish beneath.
The creamy-white flowers are borne on plume like panicles up to 3 feet long, during mid to late summer.

|Germination||Seeds should be sown in the early spring. No special pre treatment required. <br /> Sow in moist soil, keep warm and in light position (no direct sunlight for germination). Germination in 2 weeks but can be irregular and spread out over 4-6 weeks.<br /> When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in the dormant season. Basal cuttings in late spring. Harvest the shoots with plenty of underground stem when they are about 8 - 10cm above the ground. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer. Cuttings from the axils of larger leaves in early summer. Root cuttings in the winter.|
