Stoneflower

There is a Persian song, the only song in Persian i can sing a verse of, called, literally, "I Am a Stoneflower". I'm sure the bloom has a name in English. I just don't know what it is.

An excerpt:

What can i speak
of my heart in a knot*
Like the Sun
If for me You don't shine
I'm cold and discolored.


*Literally "tightened heart", an expression used when missing someone
