Clear an area with full sun. Loosen top layer of soil to allow germinating seeds to penetrate the surface. Poppies are self-seeding annuals in cooler climates or perennials in warmer climates, with the exception of P. orientale which is a hardy perennial in most regions.
Direct seed in fall, winter, or early spring before the last frost. Seed needs light to germinate. Sow seeds on top of soil and press down lightly. Seeds germinate within 20-30 days. Thin seedlings so that mature plants are 6-12” apart, depending on desired density of flowers.
Annuals flower in the first year, while P. orientale will flower in its second year. Harvest flowers in the morning to avoid moisture loss. Cut stems where they meet leaves for optimal healing of plants. After seed pods have completely dried, open seeds and pour into a non-porous container as seeds are very small.
Store seeds from poppies with edible seed in a dry, air-tight container. Poppy flowers tend to not store well, and only last for a few hours in water.
After seed pods have completely dried, open seeds and pour into a non-porous container as seeds are generally very small.
