Because of their short life span and opulent appearance, cherry blossoms simply make people happy when they see them. This is reason enough to get this beautiful flower tattooed on your body, but the cherry blossom also carries other meanings.
Their short life lends the cherry blossom to meanings of fleeting moments and the duality of life and death (via Pacho Tattoo). In this way, cherry blossom tattoos are great to get in remembrance of someone you have lost. They poetically symbolize the blossoming of love in the heart, and even though life is short, the cherry blossom reminds us that we will see those we love again someday in whichever afterlife you believe in. On a lighter note, cherry blossoms also represent the fleeting moments of the everyday. These moments may not hold as much weight as lives lost, but they are represented by this flower nonetheless.
As always, have fun when making your final tattoo decisions, and always remember to take care of them once you get them.
