What is the difference between cherry blossoms and plum blossoms?

The easiest way is by observing the following two differences. First, pay attention to the petals. The cherry blossom is usually spiky at the end of each petal whereas the plum blossom is more rounded. Second, you can tell by the smell. True cherry blossoms have a faint smell, with the exception of some rare trees. Plum trees have a strong flowery smell.
