Green Roses?

When I was a kid, I used to laugh at green flowers... how can green flowers be possible? wouldn't they look like their stems?

today, while walking to work, I saw these with my very own eyes, they are very beautiful. Unfortunately, I wasn't able to take a picture, I was rushing to work and this image wasn't able to capture their beauty very well... when you see those green roses, you will know what I mean. For now, let me rant on with a vague description (in point form)

- very distinctively green
- silky/pastel colour
- very eye catching
