Papaver rhoeas ‘Shirley Poppies’ – Colours from the brightest scarlet to pure white with all shades of pink in between and all varieties of flaked and edged flowers. All that and one of the easiest of plants to grow – just sow and forget, and lots of seeds to do just that.
Sow Papaver rhoeas ‘Shirley Poppies’ seeds outdoors from spring to early summer in short drills 12mm deep at around 20°C. Cover lightly with soil. Staggered sowings through spring will extend the flowering season. Seeds are best sown directly where they are to flower. Seeds germinate in less than two weeks. The seedlings will appear in rows approx 6 to 8 weeks after planting and thin the seedlings out so they are finally 10 to 15cms apart by early summer. Compost should be kept slightly moist, but not wet at all times.
