This is a lucky time to give flowers because May is maybe the month when most flowers are in bloom and can be given as gifts.
There is a wide variety of choices and many times what is given is either based on whatever everybody else gives, or on what are mom's preferences.
The most common blooms that people give are roses and tulips and this is going on for generations already.
These are blooms that are in everyone's comfort zone and you just know that you can't go wrong with them.
However what if you want to be a bit different from the crowd, what if you want to surprise your wife or mom with something else than the usual, what would you go with then? One of the other types of floral arrangements given for this occasion is a bouquet of carnations.
However if she doesn't like this particular type, here is one tip for you: find out in advance what are her favorite flowers and colors, and buy her that.
Even if it goes against everything you've learned before that you should give to Mother's Day, as long as you make her happy with them, you can give her anything.
And the second tip is: never buy her only flowers.
They are a necessary and expected gift, but you should buy her an additional gift as well: a fruit basket or a fruit bouquet along with the blooms will make her really happy.
Or something handmade that she will appreciate, either something carved, or a personalized greeting card, there are many things that you can give, without having to spend money on gifts.
And believe me, moms prefer getting something that her child or husband made to a non-personal gift from the internet or local gift shop.
