I was looking for something like this in order to plant on a urban brownfield in my are that needs to be recultivated. I would like to add the plants for the area, as they are not in the database. Would you be able to recommend where I would be able to to find these? I did not find it in the readme. If there is a specific procedure to follow (i.e. referencing botanical texts), it would benefit from being added. Thanks!
