Why do water lilieis not grow new leaves in winter?

Water lilies do not grow new leaves in winter primarily due to the colder temperatures and reduced sunlight, which slow down their metabolic processes. During this dormant period, the plants conserve energy by minimizing growth activities. Additionally, the water temperature drops, making it less favorable for photosynthesis and nutrient absorption, further inhibiting new leaf development. As spring arrives and conditions improve, water lilies resume their growth cycle.
