I found this pretty flower in the pot of cactus.
At first I think it is a kind of grass or 'Mi-zu-hi-ki so-u'.
But I learned that it is a flower called 'Coral flower';(Ha-ze ra-n) reading an article of other person's blog.
It blooms around three or four o'clock in the afternoon, so it is also called 'Sa-n-ji so-u'.
