Dave’s Garden’s PlantScout searches listings from 77 vendors (as of July 2018). Searching for a plant will generate a list of linked nurseries that report selling it. From the results page, the plant name link goes to the Plant Files database; “purchase” goes to the nursery’s web site; while the nursery name link goes to a list of all the plants offered by that nursery. The nursery inventory page has a link to the Garden Watchdog customer review page for that nursery. Vendors pay a yearly fee to include their inventory in the database, but it is free to visitors.
