Himalayan blue poppies (Meconopsis betonicifolia) are native to Tibet and thus require cool temperatures to thrive. The blue poppies bloom in the spring and, like the hydrangea, the depth of the color can be changed by adjusting soil pH. Acid soils tend to produce a truer blue colored flower, while alkaline soils make the poppies violet. The baggy method is the easiest way to propagate Himalayan blue poppies and should be started in February or March while temperatures are cool.
Moisten the paper towel, and wring out excess water.
Place the Himalayan blue poppy seeds, evenly spaced, on the paper towel. Roll up the towel, and place it in the plastic bag. Seal the bag, and place it in the crisper section of the refrigerator. Allow it to remain there for four weeks.
Mix together equal parts of ericaceous compost, standard compost and perlite. Water the mixture until it is moist, not soggy.
Fill each cell of a seeding tray, to within 1/4 inch of the rim, with the planting medium.
Remove the Himalayan blue poppy seeds from the refrigerator, carefully unroll the paper towel and remove the seeds. Place them on the surface of the planting medium, and do not cover them with soil.
Place the seeding tray in an indoor area that receives bright light (not direct sun) and remains cool (no warmer than 64 degrees Fahrenheit). Check the soil frequently and use the plant misting bottle to moisten it if it appears to be drying. Your Himalayan blue poppy seeds should germinate with two to four weeks. Transplant them into individual pots when they have their third set of leaves.
