Question:
Why are some plants purple on the outside?

Replies:
Most plants are green because of the chlorophyll that is important for photosynthesis. Purple colors come from anthocyanin pigments. In the wild the different color may offer some advantage like protection. House plants may be bred especially for their different colors.
