The buds of this plant have either died due to the lack of water, or because their season is over. Normally plants are adorned with colourful flowers and buds, but in this case the only colour present on them is brown, which is not really known for its vibrancy. Perhaps after these dry buds fall off new ones will emerge and the plant will not look so dull, but for now the plant is stuck with its appearance.
This photograph is a depiction of change and transition: The plant is in the process of replacing its old flowers with newer, healthier ones. The first step in this process is to get rid of the old flowers. The details of the buds are visible.
