How to Grow Papaver poppy
An ancient Latin plant name of doubtful origin, but possibly derived from the sound made in chewing the seed (Papaveraceae). Poppy. A widespread genus of 100 species of colorful hardy annual and perennial plants. Poppies like full sun, although some will flower reasonably well in partial shade. The newly unfolded petals have the appearance of crumpled satin and many varieties have a glistening sheen on the blooms. They produce seed freely and many hybrids have been raised which are very decorative and easily grown. When used as cut flowers they will last longer if the stems are burned when they are cut before putting them in water. This seals the milky sap in the stems.
Perennial species cultivated P. alpinum, 6 inches, bluish-green foliage in neat tufts, yellow, orange, salmon and white flowers, summer, Europe. P. atlanticum, 18 inches, orange flowers, summer, Morocco. P. nudicaule, Iceland poppy, yellow, white and orange flowers, summer, sub-arctic regions. P. orientale, Oriental poppy, 3 feet, orange-scarlet, June, Asia Minor. P. pilosum, 2 feet, leaves form a green hairy rosette, orange-buff flowers, summer, Asia Minor.

Cultivation Sow annual varieties in April in patches where they are to flower. They prefer a sunny position and reasonably good soil. Thin the seedlings to 2 or 3 inches apart when quite small. Plant the perennial varieties in October or early spring in deeply dug, loamy .soil in full sun, and top-dress with old manure or compost in March or April. Propagation of the perennials is by means of root cuttings in winter, by the division of the roots in March or April or by seed sown in pans or boxes in a cold-frame in spring or on a finely broken-down seedbed out of doors in early summer, scarcely covering the fine seeds. P. alpinum and P. nudicaule are frequently grown as annuals or biennials (for the Welsh poppy see Meconopsis).
