Mariani Plants

What Mariani Plants does

Mariani Plants is a privately held wholesale nursery founded in 1992 by Frank Mariani in Kenosha, Wisconsin, and now headquartered in Garden Prairie, Illinois. The company produces container-grown shade trees, intermediate ornamentals, flowering shrubs, and perennials for B2B customers across the Midwest — specifically landscape contractors, independent garden centers, horticultural re-wholesalers, and other nurseries. It does not sell to the general public. Mariani Plants rebranded from Mariani Nurseries in 2014 to reflect its broadened product line, and operates today as Mariani Nursery, LLC under trademark license from Mariani Enterprises, LLC.

The company's core production assets span a 120-acre container range and propagation facility in Garden Prairie, IL, an 18-acre Mariani Plant Center (MPC) sales yard in Kenosha, WI, and three climate-controlled propagation greenhouses. Its flagship technical differentiator is the proprietary Accelerator® container program — a root-pruning container system designed to eliminate girdling roots and accelerate landscape establishment versus traditional balled-and-burlapped (B&B) material. Mariani propagates over 75% of its container shrubs in-house, runs a successive ten-round perennial planting schedule (February–August) for season-long availability, and produces 650,000+ perennial containers, 300,000+ shrubs, and 11,000 Accelerator® trees annually on a relatively compact footprint.

Mariani generates revenue through wholesale one-time sales of plant material across four streams: container shrubs, perennials (representing roughly one-third of sales), Accelerator® trees, and propagation liners. It is a licensed Gold Key Grower for Proven Winners® and, as of 2025, a licensed propagator of Bailey Nurseries' First Editions® shrub line. Distribution is sales-led and event-driven, with inside/outside sales representatives, a Midwest delivery fleet (5 box trucks and 2 semis logging ~10,000 miles/week), direct delivery, nursery pickup, and an online ordering/prebook platform. Pricing follows an annual tiered "Earned Volume Discount" model tied to prior-year purchases, billed Net 30 F.O.B. Garden Prairie.
