The 2015 Tree and Flower Awards will begin later on today. Since previous winners cannot compete (except for stories that competed in the WIP category, but are now complete), here are links to stories which won in previous years. Stories that competed, but did not place are still eligible. Please check these lists to be certain that your nomination is eligible.
The only other eligibility requirements are that the story must be posted at the Many Paths to Tread Archive prior to July 26 of this year.
Winners from 2012
Winners from 2013
Winners from 2014
In addition, please be sure to check other nominations by other people, to make sure that someone else has not nominated the story already.
