Can you save zinnia seeds from cut flowers? If the flower has dried out on the plant, yes. If the flower was cut while in full bloom and dried out after being on display, then there’s a possibility that the seeds were not yet mature and ready for saving.
What do viable zinnia seeds look like?
The seeds will be arrowhead-shaped, pointed on one end and broader on the other, each having a raised spine running up its back. They will measure about 3/8 to 1/2 inch long, if harvested from medium-sized zinnias, and usually slightly less than 1/4 inch across at their widest point and brownish in color.
Do zinnias reseed themselves?
Zinnias (Zinnia spp.) reseed easily, creating a cut-and-come-again garden each summer, says the University of Wisconsin Extension. Heirloom varieties, cultivated for more than 50 years, are open pollinated and grow into plants identical to their parents.
What month do you plant zinnia seeds?
Planting: Plant zinnias in spring after all danger of frost has passed, around the same time you’d plant tomatoes. Zinnias are easy to grow directly-seeded into the garden. For sooner blooms, start seeds indoors 4 to 6 weeks before your last frost date.
Do zinnias come back every year?
Zinnias work year after year. It’s easy to save zinnia seeds. Simply let the flowers dry fully on the stem, then collect the seedheads and lightly crush them in your hand to release next year’s seed crop.
How do you separate zinnia seeds from chaff?
Lay out a tarp or sheet and put a flat box in the center. Put the seed and chaff on a cookie sheet and place the cookie sheet on the box. Turn a fan on so the air blows across it and lift the end of the cookie sheet so the seeds roll down. If need be, repeat until the chaff has blown off.
