It would be difficult to hide "coded" plants (that look slightly off) unless there were also real plants mixed in.
An alternate way of thinking about it is that the idea was originally to drawn a collection of plants, but after looking at mnemonics, ideas come to mind (to someone with a fertile imagination) and it morphs into something more, something original.
