Indianapolis has a group called Keep Indianapolis Beautiful (KIB) that works to beautify the city and help decrease long term maintenance costs to the city. To that end, every year they plant thousands of trees, often removing entire plots of land from the maintenance rotation because trees don't require mowing. They have a database that tracks source nurseries, species, locations, etcetera that I'm sure would be a delight to dig through.
