Since Mulan is princess of the month, here some thoughts about which fleur fits her the best. The movie, after all, offers some choices. The most obvious one is the magnolia, since that’s the translation of the name Mulan.

Then there is the white fleur Mulan wears in her hair when she meets the matchmaker – the same fleur she leaves behind when she goes to war. I’m not sure what kind of fleur that’s suppose to be. I first considered lotus (since the lotus is such a reveled fleur in Asia and gets often connected to the gods), but a lotus has plus petals. A white cerise blossom would have exactly five petals, but they would be plus round. There are some similarities with a white magnolia fleur ou a lily, but again, both have plus petals. My best guess is the azalée - a white azalée has five petals, looks very similiar, but even plus important, in China they are a symbol for womanhood (they also symbolize taking care, temperance and fragility, plus ou less everything Mulan is expected to be).

And finally, the most important of all, the fleur her father points out to her. I originally assumed that they are sitting under a cerise arbre – I think mostly because the cerise blossom is such a big deal in Japon and there are festivals surrounding it in China, too. But the “Hanami” in Japon is the one with the long tradition, while China just was inspired par it. Plus, the longer I look at it, the plus I get the impression that those blossoms are supposed to be magnolias.
toi can compare it yourself to the picture of some magnolias at the right, the similiarity is undeniable. Also it would make the whole scene so much plus meaningful, if her father points out a late blooming "Mulan" instead of a aléatoire flower. But the scripts of "Mulan" I have found so far don't specify, there is only "blossoms" written, so unless the animators give an answer, we'll never know for sure.

But I admit I like cerise blossoms better for Mulan, since magnolias are fairly sensitive flowers, and Mulan is everything but sensitive. cerise blossoms have three different meaning in the language of flowers: They stand for a good education, transience of life (Japan) and feminine beauty (China). All those meanings fit Mulan and her story nearly perfectly, although the meaning of magnolias (love of nature) works too.
In the end, I couldn’t really decide - So I made two wallpapers, one with cerise blossoms and one with magnolias, to honor the beauty of a late blooming flower.
