Homegrown National Park - Doug Tallamy and Michelle Alfandari's movement to turn private yards into a distributed "national park." Its Ecoregion Finder gives you your EPA ecoregion and a keystone-plant list by ZIP code, and the Biodiversity Map lets you register your own plantings alongside ~50,000 other participants. Their "10 Things to Get You Started" page is a good first stop for anyone new to this.

National Wildlife Federation Native Plant Finder - enter a ZIP code to get a list of native plants ranked by how many butterfly/moth species they support, built on Tallamy's research. Good complement to the Homegrown National Park tool.

Xerces Society Pollinator Conservation Resource Center - region-specific native plant lists, habitat establishment guides, and local seed vendor lists for pollinator habitat. Their Pollinator-Friendly Plant Lists are useful for choosing plants for bees, butterflies, and moths specifically.

Tennessee Invasive Plant Council (TNIPC) - the go-to for identifying invasive plants before you start removing/replacing anything. Their Landscaping page has an "Invasive Plant Primer for the Home Landscape" walking homeowners through ID, control, and post-treatment native replanting. UT Extension's companion publication, A Guide for the Identification and Management of Invasive Plant Species (W 1198), is a downloadable PDF field guide.

UT Extension Soil, Plant and Pest Center - $15 homeowner soil tests (lawn/garden). Get a sample box from your county Extension office or use a zip-top bag; results come back by email in about a week. A sensible first step before planning any planting.

Tennessee Native Plant Society (TNPS) - Nashville-based nonprofit (est. 1978) for Tennessee flora. Publishes field guides (Wildflowers of Tennessee, Guide to the Vascular Plants of Tennessee, etc.), maintains the Tennessee-Kentucky Plant Atlas, and runs field trips, talks, and plant sales/swaps which are a good way to meet other native-plant people in the state, not just a reference source.

Nature's Best Hope: A New Approach to Conservation That Starts in Your Yard - Douglas W. Tallamy. The headliner. Tallamy's argument that because most U.S. land is privately owned, public conservation land alone will never be enough - private yards, neighborhoods, and cities have to become a distributed "Homeland National Park." Practical in the back half: which native "keystone" plants matter most, and how to do this without starting a fight with your HOA or neighbors.

Bringing Nature Home: How Native Plants Sustain Wildlife in Our Gardens - Douglas W. Tallamy. Tallamy's earlier (2007) and foundational book, the one that introduced the core idea that most native insects can't or won't eat non-native plants, which is the ecological argument the rest of his work (and this movement) builds on. Read this for the "why," Nature's Best Hope for the "how."

The Nature of Oaks: The Rich Ecology of Our Most Essential Native Trees - Douglas W. Tallamy. A deep dive on one keystone genus, oaks, and everything from caterpillars to birds to soil health that depends on them. Useful if a property has (or could have) oaks and you want the case for keeping/planting them.

GroWild, Inc. - Fairview, TN (Williamson County). Retail & wholesale, 1,000+ species/cultivars of native perennials, wildflowers, trees, shrubs, ferns, vines, and grasses. Visits are by appointment only (Wed–Fri, call ahead).

Wonder Gift & Garden - Kingston Springs, TN (1114 US-70). A native plant focused garden center that also includes an amazing assortment of nature-inspired, intentional gifts.

Bates Nursery & Garden Center - Nashville, TN (3810 Whites Creek Pk.). General retail garden center with a dedicated TN/ Southeast native plants section (native shrubs, perennials, trees), plus an online shop with live inventory. Open daily. The easiest option on this list if you want a walk-in retail experience rather than an appointment-only specialty nursery.

Gardens of Babylon - Nashville, TN (900 Rosa L Parks Blvd). A large garden center and landscape designer with a dedicated native plant section.

Cheekwood Estate & Gardens - Native Plant Sale - Nashville, TN. Not a year-round vendor — an annual one-day sale hosted by the Garden Club of Nashville (19th annual sale held April 2026), featuring native plants, flowers, and shrubs, with garden experts on hand. Worth putting on a calendar rather than treating as a drop-in resource.

Tennessee Native Plant Society - plant sales/swaps, not a nursery itself, but TNPS organizes sales and swaps (in addition to field trips and talks) that are good sources for locally sourced genotypes, not just nursery-grown cultivars.
