It is not always a good idea to keep intensely fragrant flowering plants or cut flowers in the bedroom at night.
That’s because some very fragrant blooms, even if they are often quite enjoyable during the day, can impair sleep at night, even causing nausea or headaches in very sensitive people. It’s therefore better to place hyacinths, hoyas, lilies of the valley, brugmansias, paperwhite narcissus and other plants with very heady perfumes in another room at night, at least while they’re in bloom.
However, they can return to the room for the day … assuming, of course, you’re not trying to sleep during daylight hours!
That said, the scent of other plants is said to have the opposite effect and can stimulate sleep. Thus, most people find there is no need to remove jasmines, gardenias and lavenders from the bedroom, for example. In fact, they often sleep better when they’re nearby.
If in doubt, experiment a little. Place the plant (or cut flower) in the room just before going to bed. If the perfume starts to bother you, just remove the plant, but if you wake up the next morning feeling relaxed and refreshed, it’s a keeper!
