Hello everyone,

I came across a simple yet pretty flower arrangement at a hotel's lobby last week during work luncheon event. The main flower caught my attention immediately since it's huge and has a very unique lime green color. It has a long and firm stem and the bloom looks exactly like shasta daisy except it's lime green color (with darker green center), plus the flower's size and proportion reminds me of sun flower. Can anyone tell me the name of this flower pls? I'm sorry I don't have any pictures and I've been searching the internet for information with no success. Any help will be greatly appreciated. Thanks again.
