Father's Day is 4th largest card sending occasion with 87 million cards given every year. Over half of them are given to Fathers, while 15% are given to husbands. The majority of them are humorous in nature.
Traditional gifts for Dad include neckties, shirts, golf clubs, fishing rods or any item from one of the many hardware stores in the US. It's probably safe to assume that the majority of meals eaten on Fathers Day, are Bar B Que.
Though it may be surprising some Dads receive flowers on Fathers Day.
Roses are the official flowers of Fathers Day.
There is an older tradition where a red rose is worn on your lapel if your
Father is living and a white rose is worn if your Father is deceased.
