I tend to associate floral-patterned palettes with spring, but this offering from ArtDeco for their fall 2012 Mystic Garden collection made me think of pretty fall blooms. These look like dahlias and chrysanthemums, rendered in autumnal shades of magenta, plum and fiery orange.
The white outlines do lean a little spring-like, especially when compared to the ones in several pieces from Marni's spring 2013 collection.

Overall though, it definitely feels more like fall. I won't be buying this but I do think ArtDeco did a nice job of creating a seasonally-appropriate floral palette.
