I know you guys probably thinking I'm straining my eyes too much ;0)

but I know that I'm seeing turquoise/aqua in the style-midribs of this one.

It'll be along way to go but these two beauties are in the Iridaceae:

Ixia viridiflora

and Lachenalia viridiflora

So it's within the realm of possibilities.
