Here's a flower you don't see too often. I like all the different curving lines. Here is an interesting bit of Wikipedia trivia: "These plants are related to garden cress and mustard, noteworthy for a peppery, tangy (pungent) flavor. The name Nasturtium comes from the Latin nasus tortus, meaning "twisted nose", in reference to the effect on the nasal passages of eating the plants."
Hmm... I wonder if that means they clear your breathing passages? The flower is very pretty but now I'm really curious about it's "medicinal" qualities.
