Shade conditions means less than three hours of direct sunlight a day, with filtered sunlight during the rest of the day. Full shade does not mean no sun. There aren't many plants, except mushrooms, that can survive in the dark. There are very few plants that actually require shade. Most are better thought of as "shade tolerant," and will usually thrive if placed in partial sun conditions as well.

          Plants graded as full shade will wilt if exposed for long periods to direct sunlight. If these plants are in direct sunlight for too long, the sun will weaken and take the moisture from these plants.

         If you would like a shade loving plant in a particular position you can always create shade conditions with a screen or by planting larger plants in a position to shade them.
