Explanation: 

Detailed explanation-1: -More than 250 species of dandelions have been identified, and unless you’re a botanist, you may find it difficult to tell the difference between types of dandelion plants.

Detailed explanation-2: -The genus is native to Eurasia and North America, but the two most commonplace species worldwide, T. officinale (the common dandelion) and T. erythrospermum (the red-seeded dandelion), were introduced from Europe into North America, where they now propagate as wildflowers. Both species are edible in their entirety.

Detailed explanation-3: -Dandelions grow from seeds and do not spread asexually from stolons or runner; they have a single tap root. However, they can and do reproduce asexually by seed. They are capable of producing viable seed without need of cross-fertilization, a process known as “apomixis".

Detailed explanation-4: -If you are like most people, you’ve wondered what the difference is between white and yellow dandelions. Why do two different weeds have the same name? The truth is, white and yellow dandelions are the same type of weed, just at different stages of development. Both are distraction when you want a green lawn in Utah.
