Cherry trees are hermaphrodite, meaning both male and female reproductive parts are contained within the same flower. Flowers appear in April, they are strongly scented, white and with five petals, and measure 8-15mm across. once pollinated by insects, the flowers develop into reddish-black, bitter cherries.
