Dandelion fruit. Dandelion spreads seeds through the wind. Dandelion usually blooms yellow flowers first. After a period of time, after the golden petals fall off, white fluff balls will grow on the receptacle, which is both its fruit and seed. When the breeze blows, the seeds will drift to other places with the wind. If it falls to a suitable place for growth, the seeds will germinate next spring and continue the previous cycle.

Dandelion is a perennial plant. In the wild, biennial plants can blossom and bear seeds. In early summer, the number of flowering and fruiting seeds increases with the growth years. Some plants open more than 20, and excellent varieties can open more than 20. After flowering, the seeds will mature in 13- 15 days.

The shell of the disk changes from green to yellow-green, and the seeds can be harvested from ivory to brown. Don't wait for the disc to crack before harvesting, otherwise the seeds will easily fly away and lose a lot. Generally, the number of seeds per flower head is above 100. The 1000-grain weight of Taraxacum macrophyllum seeds is about 2g, and that of Taraxacum microphyllum seeds is about 0.8-1.2g. ..

When collecting seeds, you can take off the dandelion tray and store it indoors for a day. After the disk is completely scattered, dry it in the shade for 1-2 days until the seeds are half dry, rub off the fluff at the tip of the seeds by hand, and then dry the seeds for later use.
