" Conversely, the red plant itself burns a brighter red when set off by the green than when it grows among its peers. In the bed I always reserved for poinsettia seedlings, there was little to distinguish one plant from its neighbours. My poinsettia did not turn scarlet until I planted it in new surroundings. Colour is not something one has, colour is bestowed on one by others. "
