This is the plant at the Life Science building. The growth of this plant is seemingly similar to mine as they are both growing flowers. The difference I'm seeing though is that the flowers growing in this plant seem to be pink and mine are purple. This may be caused by various reason like the colour of the plant as mine is Red and the one at the building is white. Other reason could be how much these plants are exposed to sunlight.
Green in the plant is caused by the algae growing in the water. If the jar was cleaned when the water change was made then there would be no algae growing.
