The light is too strong. Persian red grass is a plant that likes semi-shade. If the light is too strong during the breeding period, the water on the leaves will evaporate quickly, and the leaves of Persian red grass will appear scorched. Persian red grass, plant height 10-20cm, leaves opposite, oval-lanceolate, leaf margins have fine serrations, leaf veins are obvious, stems and leaves are covered with fine hairs, and are covered with purple spots, and the back of the leaves is purple-red. Quite elegant.
