Trusted by growers & distributors nationwide
































GreenSource holds membership with the associations that represent wholesale growers, nurseries, and florists nationwide.









Built by horticulture industry insiders who were tired of spreadsheets, phone tag, and missed deals.
Browse thousands of plants, annuals, perennials, tropicals, and hard goods from wholesale suppliers — all in one place.
Suppliers upload a CSV, Excel, or PDF availability list and the smart-fill engine auto-fills freight dims, categories, and botanical names — review and publish in one pass.
Lock in grow-to-order commitments before crops are ready. Suppliers send formal contracts with deposit terms and cancellation schedules — all tracked in-platform.
Score end-of-week deals through dynamic price-drop auctions. Prices fall until stock clears — first come, first served.
Submit custom price offers on any listing. Suppliers can accept, counter, or decline — real negotiation, digitized.
Suppliers are rated by buyers after completed orders. Fulfillment methods, shipping range, and uploaded compliance docs shown upfront — do your own diligence.
Both buyers and sellers build reputations over time. Ratings keep the marketplace honest and quality high.
Request specific genera you're looking for. Get notified when a supplier lists exactly what your operation needs.
From signup to your first order in minutes.
Sign up as a buyer, seller, or both. Tell us about your business in under 2 minutes.
Buyers search the live catalog. Suppliers list stock one at a time or bulk-import an availability list — the smart-fill engine fills in freight dims, categories, and botanical names automatically.
Add to cart, place a bid, or jump into a Friday auction. Flexible purchasing, your way.
Orders are managed end-to-end. After delivery, both sides rate each other to build trust.

"As a grower, the GreenSource platform has been an invaluable tool for connecting us with local companies seeking assistance with their tree acquisition needs. It has helped streamline the process of identifying potential buyers, building relationships with local businesses, and creating new opportunities to move our trees into the community."

Sales/Project Manager · SuperTrees Colorado · DENVER, CO
"As a landscape construction project manager, I’m constantly sourcing specific plant material, and this website has been such a helpful tool. It’s very user-friendly, offers secure payment options and helped me find plants I couldn’t locate on my own after checking with several nurseries. The request feature is awesome and takes so much of the legwork out of finding hard-to-source material. After receiving my first load, I was very happy with the quality of the plants. They were even able to deliver early, but they called ahead to confirm instead of just sending the truck, which I really appreciated. Scott has been incredibly helpful throughout the entire process. I’m excited to keep using this tool and can’t wait to see how it grows!"
