Make Like a Tree

If you aren't your parent's pride and joy, will anyone else ever acknowledge your life's work?

AKA: Stupid, silly found family made up of plant loving thieves.
They all have names that are "Firstname Plantname Leaf". They are given these names when they join the group as like, aliases or smthn, it's not super serious but, yeah, they have these names and then they have their real names, lol. They keep their real names secret from the authorities but most of them know one another's real names.
