When to worry

Stopping it coming back

- Will my dayflower bloom indoors?
- Yes, it can bloom indoors if it is placed in a very bright window. It needs significantly more light than most common houseplants to produce flowers.
- Do I need to deadhead the flowers?
- The flowers are very short lived and usually drop on their own. You do not need to deadhead them, but you can snip off spent stems to keep the plant looking tidy.
