The New York Botanical Garden (fragrant orchids) says most fragrant orchids are strongest in the morning when the light is bright, and that the scent fades as afternoon heat builds. Some are evening-scented: Brassavola nodosa, the queen of the night, begins at dusk when its nocturnal moth pollinators appear. The page also says sunny days increase scent and high humidity makes it linger longer.
What the NYBG says
| Time or condition | What happens |
|---|---|
| Morning, bright light | Most fragrant orchids are strongest |
| Afternoon, heat building | Scent fades |
| Dusk | Brassavola nodosa starts to scent |
| Sunny day | Scent increases |
| High humidity | Scent lingers longer |
Why timing matters
If your orchid seems to smell faint, the sources point to checking the time of day and the warmth. The NYBG ties evening scent to moth pollinators. The wider question of why flowers smell stronger at night is covered in Why Do Flowers Smell Stronger at Night?.
What the source does not cover
The NYBG page is from 2010, gives no scientific sources for its scent and pollination claims, and gives no indoor care. For other orchids, see Fragrant Orchids for Indoors.
