This seems like a good idea. Outcasts would be able to expand and operate away from Alpha (where they have to fight daily to survive.... =CR=, GRN). Would provide them with the means to operate in systems that have outlawed them for smuggling. I can see some good rp from this (provided they are only selling to other outcasts). With some good diplomacy skills some really interesting story/rp could be developed. Kudos to OP!
As far as I know, the Nomad Lore (the one written by Chris Todd) only says that cardamine was planted/created on Planet Malta. I don't think it says anything about the possibility of cardamine being grown elsewhere. The only reason why so few planets grow it is most likely because very few planets have the same soil and ecosystem as Planet Malta.
