Flowers have a long history of symbolism that you can incorporate into your writing to give subtext.
Symbolism varies between cultures and customs, and these particular examples come from Victorian Era Britain. You'll find examples of this symbolism in many well-known novels of the era!
Been a while but i need to vent. Coming up with story ideas is really good except when the imposter syndrome hits and you start to wonder how you ever thought you could write something like that because obviously you can’t because obviously you aren’t a real writer and not even a good one. So what if you have a really good idea that’s complex with themes and intertextuality and has layers and insight - there’s no way you can write it because you suck at writing. So you put it off until you have the skill except you never gain the skill because you’ll always be bad and never good enough to write anything noteworthy. That’s how I’m feeling right now; pretty hard done by and sorry for myself.
