What colours of roses you think mothers love?

Pink. Different colors of flowers have different traditional meanings. Pink means loving affection, red means romantic or passionate love, yellow is what you give to someone who is a friend.

There are some colors of roses, and roses with more than one shade, that didn't exist when these centuries-old traditions arose, so you could also give your mother lavender roses or ones that have peach shading to pink, for example.

Other colors besides red and yellow that you should not use for your mother on mothers' day are solid white (it signifies virginal purity, which obviously she's not or you wouldn't be here) and dark purple (very rare anyhow, but flowers that color are too often used for funerals).

And you can ignore all this if your mother is not at all traditional and just pick out what you think looks prettiest.
