Fragrant Orchids These are Orchids that we have noticed to be fragrant in our greenhouse, under our conditions and care. Different growing conditions may get different results. Some Orchids are fragrant in the morning. Some are fragrant at night. Some are not fragrant right away and get more fragrant as the flower ages. Some will fill a room with fragrance, others will require your nose to be right in the flower. Fragrance is usually stronger in natural light as opposed to artificial light. Stronger on a bright/sunny day, then on a dark/cloudy day.
