Im sure whatever you give her she will still enjoy it!!! my son picked me out gifts for mothers day and the first yr I got fake flowers and last yr he picked me out a plain black pen!! He ended up keeping the pen and lost it but it was still cute that he was all excited to get me something... I think if you really dont want to spend money and dont want to do the other idead then maybe pick some flowers and put them in a vase and write her a note with a card telling her how much she means to you..
