Definition & Meaning of "tall poppy"in English

What is the origin of the idiom "tall poppy" and when to use it?

a poppy is a type of flowering plant that is known for its bright, colorful petals. In ancient Greece, poppies were commonly grown as a crop, and farmers would often cut down any poppies that grew taller than the others. This practice was seen as a way to ensure that the entire crop would be harvested at the same time and would be of a consistent quality. Just as the tall poppies were cut down to make sure they did not grow taller than the rest, successful or outstanding individuals might be criticized or resented for being different and standing out from others.
