Why some flowers only bloom during night ?
Those plants whci have white flowers and depend on insects for cross pollination bloom only during night The colour of the flower, that is white colour, is a genetic trait Flowers blooming during daytime are usually very clolourful and the insects will naturally be attracted towards these brilliantly coloured flowers In such a situation, the white flowers have the least chance of pollination by insects So, blooming during the night time is an adaptation aquired by these plants during the evolutionary process White flowers are more visible during dusk and night and the plants with white flowers have an edge over plants with colourful flowers during these timings The sweet smell of the white flowers is another aspect of the adaptation for survival, as a species Answered by thampy chacko, 07 Jun ’09 02:10 pm
