Green hibiscus, real or photoshopped?
Photoshop for sure. There are some hibiscus that are sort of greenish, but they're a very olive greenish/brownish color, nothing anywhere near a true green. For some reason tropical Hibiscus seem to be a favorite plant to photoshop, especially by unscrupulous sellers trying to rip people off so anytime you see a very unusual color I would definitely be suspicious.
Look at the ‘photographers’ library if you think any of these are real.
Don’t cast all the blame on tropical Hibiscus growers, some the growers of hardy Hibiscus just a bad, just a bit less outrageous.
Yep, they all have had the colors tweaked. Too bad, because the blooms are dramatic enough, no need to mess with them!
