Orchids have green roots because they contain chlorophyll, which allows photosynthesis to take place. Wild orchids are epiphytic, meaning they grow attached to other plants, with their roots exposed to light.
If your orchid is flowering and the roots appear otherwise healthy, but have no green tips, do not be alarmed. Continue to provide the orchid with what it needs and once the plant reaches the vegetative stage, the roots will start to grow and develop new green tips.
