Reasons for Purple Leaf Lucky Clover Leaves Turning Green1. Insufficient lighting
The purple leaf lucky clover is native to Japan and prefers a semi-shaded environment. If it is exposed to insufficient light for a long time, the leaves will gradually turn green and lose their original purple color. Maintaining moderate lighting is key to keeping the leaves of purple leaf lucky clover purple.
