The bird of paradise is a plant that often symbolizes the end of a relationship. The curls can be interpreted as hair, and when your bird of paradise starts to curl up it could be a sign that the relationship is over and that your partner is starting to move on.
Nature has always been our best friend in times of need. This goes even more for times when we're trying to figure out what's going on in our love life or relationships. When we see flowers starting to curl up, it means they are dying and wilting away.
When a bird of paradise (Strelitzia reginae) starts to curl it leaves on its own this can be happening when their water source dries out or if the plant is not cared for properly. The curling of leaves on the plant may be an indication of over watering or too much sun exposure.
