The difference between white asparagus and green asparagus is the color. White asparagus is a little more expensive than green asparagus. There is basically no difference in the rest. They are the same plant, but the planting process is different and the color is different. The green color of green asparagus is the result of complete photosynthesis, while the entire growth process of white asparagus is completely invisible to light. As long as it grows a little bit, it must be covered with soil to completely avoid light, so the color is white.
