Begonia Leaves And Stalks Are Turning Red

Question From: TEXAS
Q: Begonia leaves and stalk turning red...too much sun?

A: According to the American begonia society: This may *be* a function of the *red* pigments in the layer of cells on the underside of some *begonia leaves*. ... In the spring when temperatures rise and light intensity increases, the *red* pigment forms on the *leaf* edges of many plants. It acts as a sunscreen to protect the plant from an increase in ultraviolet rays. Best Nancy and Happy Yardeing
