I'm not sure I would say flowers are a photographic trend more of a seasonal photographic possibility.
The photo itself though is very good, the focus is good, the colors are good and overall it is a very eye pleasing photo. I think what it lacked here is it needed to work into the challenge "Trends" better.
I think the composition could've been better. Tighter crop on the flowers is my suggestion. There's no real focal point here. Try shooting from a different angle as well to make it more interesting. Rather dull as it stands now.
Photographing flowers does seem to be trendy. The high contrast on this one gives it an appearance suggestive of a chinese painting (where flowers have always been a favorite subject). I like it.
