What happens when rheo leaf is kept in water?

When a rheo leaf is kept in water, it may initially absorb moisture through its cuticles and stomata, leading to a temporary increase in turgidity. Over time, if submerged, the leaf may undergo anaerobic conditions, which can result in decay and the growth of mold or bacteria. Additionally, the leaf's vibrant colors may fade due to prolonged exposure to water and lack of light. However, if simply placed in water for a short period, it can remain vibrant and healthy.
