Hostas are often called “shade loving” plants. For the average gardening public, this helps them to understand that these plants are adapted to growing in the shade. However, for more advanced hobbyists or professionals, this is a misnomer.
All vascular plants live by a process called photosynthesis. They capture the energy from the sun and, unlike animals, they make their own food. For photosynthesis to work, a plant must have five things including light, water, nutrients from the soil and the air, chlorophyll and suitable temperature. The minimum levels of each of these factors required may vary from species to species but they all must be present in certain amounts for photosynthesis to take place in that plant.
