Dandelion is a perennial plant. Under wild conditions, biennial plants can bloom and set seeds. In early summer, the number of flowers and seeds increases with the age of growth. Some single plants The number of flowers can reach more than 20, and the number of flowers per plant of excellent varieties can be as high as more than 20. The seeds will mature in 13 to 15 days after flowering.

The flower disk shell changes from green to yellow-green, and the seeds can be harvested when they change from milky white to brown. Do not wait until the flower discs crack before harvesting, otherwise the seeds will easily fly apart and cause serious losses.

Generally, the number of seeds in each flower head is more than 100. The 1,000-seed weight of large-leaf dandelion seeds is about 2 grams, and the 1,000-seed weight of small-leaf dandelion seeds is about 0.8 to 1.2 grams.
