It is interesting to note that the most traditional connotation of pink roses is of a mother's love for her child. A story has it that when Mary first saw her son Jesus carrying the cross to which he would later be crucified, she shed a tear.
That tear fell on the barren ground and from that very tear, grew the very first and most perfect pink rose.
Perhaps, this is why in the Talmud, it is written that only pink roses are allowed to bloom in Jerusalem and as a result, pink roses have come to be a symbol of paradise as well.
