This would be a good book review, there's lots of subject matter for discussion. Discussion questions can be found here.
From the cover:
After a childhood spent in the foster-care system, Victoria Jones's only connection to the world is through flowers and their meanings. Now eighteen and emancipated from the system, Victoria has nowhere to go and sleeps in a public park, where she plants a small garden of her own. A local florist discovers her talents, and Victoria realizes she has a gift for helping others through the flowers she chooses for them. But when she's forced to confront a painful secret from her past, she must decide whether it's worth risking everything for second chance at happiness.
