Saving seeds from homegrown flowers is a great way to expand the variety of flowers in your garden or flower bed at very little expense. It's also a way to save a favorite, heirloom bloom, or to trade flower seeds with friends and family. Spend a day outdoors saving seeds, and invite your kids to help. It's a fun, hands-on lesson about the cycles of nature.
Wait until the flower blooms are brown and wilted, and then choose a dry afternoon to spend harvesting seeds. Take a large paper grocery sack for each type of seed you plan to save.
Hold the paper grocery sack under the bloom, and snip off the head of the bloom with a pair of scissors. Label each sack as soon as you're done harvesting a bloom. Write the type and color of flower, and the date it was saved.
Put the paper sack in a warm, well-ventilated place, where the temperature is at least 75 degrees F, and leave the top of the sack open. Give the sack a shake every so often. When you can shake the blooms and the seeds fall out easily, and the seeds are hard, the seeds are dry. Some seedpods may need a little help. Just break them open with your fingers. Don't rush. If you're not sure if the seeds are dry, leave them a few more days.
Spread the flower seeds on a flat surface such as a cookie sheet. If the seeds are large, pick them out of the leaves, stems and petals with tweezers. If the seeds are tiny, blow carefully to separate them from the debris.
Put the flower seeds in a paper envelope, and label the envelope. Store the envelope in a cool, dry place until spring.
