why should dandelion?

well, dandelion is also called taraxacum.

Dandelion seeds are carried away by the wind and travel like tiny parachutes. A strong wind can carry the parachutes miles away from the parent plant.
A dandelion comes from many tiny flowers bunched together. After a dandelion blooms, each of its tiny flowers produces a seed. Each seed is attached to a stem with white fluffy threads. so, it might be blown away, but it will grow so many stronger flowers.
