The listing, 100 Allium Seeds 2015 Crop Plant Now has ended.
While it is popular to propagate allium from bulbs, you can grow your own at less expense by sowing allium seeds. Various cultivars thrive in U.S. Department of Agriculture plant hardiness zones 3 through 11.
Scarify the allium seeds to facilitate germination, altering the seed coat to make the seed permeable to water and gases. Either scratch each seed with a nail file or sand paper or else boil water, remove the pot from the stove, and place the seeds into the water. Drain the seeds when the water cools.
Scatter allium seeds in a sunny outdoor flower bed and cover them with one-quarter inch of soil. Plant seeds as soon as they ripen for the best chance of germination; if you keep seeds to plant in the springtime, store them in the refrigerator and expect a longer wait for flowers. Keep the ground moist during dry periods. In time each seed will form a small bulb underground and send out a shoot above ground; the shoots may die back during the winter but the bulbs will survive.
