Types of Asparagus
Green: Green asparagus is the most common type seen in produce sections. It is less fibrous than purple varieties and slightly thinner. They get their green color through the photosynthesis process.
Purple: Purple asparagus is sweeter and slightly thicker than green and white varieties. It gets its color from the high levels of anthocyanins in the plant which are high in antioxidants.
White: White asparagus is very similar to green varieties in taste, texture and size. It gets its white color from growing in the dark where it cannot photosynthesize. White varieties are typically more expensive to buy than other types because of its limited supply.
