The need to keep fuzzy-leafed foliage dry at all times is a common misunderstanding. If you think about it, all plants in their native habitats get wet leaves from time-to-time when it rains. The problem is not the moisture, but what accompanies it. For example if the water is cold, it is the cold that may damage the leaves. Or if the plant is in direct sunlight, water droplets may magnify the light and burn the leaves. Or if there are unusual pathogens (bacteria, fungus) in the air, the water may provide a good habitat for them to flourish. In my experience, overall too much fuss is made over keeping foliage dry at all times.
