Sleeping Beauties: 11+ Flowers That Close Up At Night
Plants are amazing in their complexity and habit. Within all of their wonder, there is an intriguing collection of plants that close up at night – a phenomenon called nyctinasty.
Nyctinasty is thought to protect pollen and nectar or to protect the plant from cool, chilling temperatures. Sometimes this tendency confuses people into thinking that something is wrong when they close up during the day under low light conditions.
Here is a list of flowers that close up at night (little tricksters!) so you can be on the lookout for them:
1. Gazanias – pollinated by butterflies during the day, fold up in low light
2. Hibiscus – blossoms open for just 1 day and then close at night; usually do not reopen
3. Morning Glory – bloom in the early morning, close at night, blossom lasts 1 day
4. Osteospermum – also known as African Daisies
5. Oxalis – also known as a purple shamrock with delicate white flowers, foliage folds upward
