Collecting and saving seeds from your flower garden allows you to grow an abundance of flowers without purchasing new seeds every year. Seed from standard or heirloom varieties produce new plants identical to the parent plant. Seeds of hybrid flowers, however, do not. Although seeds of hybrid plants may produce some interesting varieties, they differ significantly from the original plants. Check with a garden reference book or seed catalog to determine if your specific cultivar of blanket flower is a hybrid.
Select the healthiest plants for gathering seeds. Choose plants with characteristics you wish to preserve. Consider the blooming size and color, height of the plants and blooming time. Allow several of the largest blooms to remain on the plant after petals shrivel and fade.
Place a paper or mesh bag over the head of the flower and tie it to hold the flower head inside the bag. This prevents mature seeds from dispersing before harvesting.
Check seed heads often. Clip the seed head free of the stem when seeds are dark and dry.
Hold the seed head over a paper plate or an open bag and rub the seeds free with your fingers.
Separate the seeds from plant debris.
Place the seeds in an envelope. Label with the type of seed and date.
Store the envelope in a sealed jar or other airtight container. Store it in a dark, dry area until spring.
