For years, we at PGC have been collecting websites that are related to all things horticultural. We have extensive listings of gardens, arboreta, plant organizations and informational sites from around the world.

Now, these resources are available from our online, searchable database. You can do a key word search or visit our index pages that do the searching for you.

The indexes are provided in a wide range of options. Gardens and organizations are listed by country or state or type. Information sites are indexed by source, topics, plant species, and many more categories.

If you would like to add your site to our database or have a comment or find a broken link, please send us an email.
