What is RPR®?

The First and Only Patented Perennial Ryegrass That Regenerates

Traditional perennial ryegrass establishes quickly but grows as individual plants, limiting its ability to recover from heavy wear. Developed by Barenbrug in 2009, RPR® (Regenerating Perennial Ryegrass) became the first turf-quality perennial ryegrass to produce regenerating determinate stolons, combining elite turf quality with regenerative growth. Its unique characteristics were so distinct that RPR® was recognized as its own subspecies of perennial ryegrass. 

Then, in 2015, RPR® became the first and only turf-quality perennial ryegrass to receive a utility patent for its determinate stolon technology. Today, RPR® continues to set the standard for traffic tolerance, rapid recovery, and premium turf performance by actively regenerating worn areas while maintaining the exceptional quality expected from elite perennial ryegrass.

Why Use RPR® Technology?

High-performance turf isn't judged by how quickly it germinates, it's judged by how well it performs after months of traffic.

Whether it's cleats on an athletic field, golf carts on a fairway, or constant foot traffic in parks and recreational spaces, turf needs to recover just as quickly as it establishes.

RPR® combines the rapid establishment and premium appearance of elite perennial ryegrass with patented regenerative technology that helps repair worn areas, maintain turf density, and keep playing surfaces looking their best.

How RPR® Works

Unlike traditional perennial ryegrass, RPR® actively regenerates damaged turf.

  1. RPR® germinates quickly to establish a dense playing surface.
  2. Determinate stolons develop from auxiliary buds near the base of each plant.
  3. The stolons grow horizontally, producing genetically identical daughter plants.
  4. New plants establish roots and fill worn areas, improving turf density and recovery.
  5. The interconnected turf system continues repairing itself, helping maintain exceptional turf quality under heavy traffic.

The Difference is Determinate Stolons

The defining characteristic of RPR® is its patented determinate stolons.

Unlike conventional perennial ryegrass, which grows as individual plants, RPR® develops horizontal stolons that create new daughter plants. These plants establish roots, connect together, and form a dense regenerative turf system.

Because the stolons spread in multiple directions, RPR® can naturally fill worn areas throughout the turf rather than leaving damaged spaces to recover slowly. The result is exceptional traffic tolerance, rapid recovery, and long-term turf density that traditional perennial ryegrass simply can't match.

Why RPR® Is Different Than Other Ryegrass

Traditional perennial ryegrass establishes quickly but relies on individual plants to recover from damage.

RPR® creates an interconnected network of plants through determinate stolons, allowing worn areas to regenerate naturally while maintaining the dense, attractive appearance expected from elite perennial ryegrass.

The result is turf that not only withstands heavy traffic but continues improving as the regenerative network develops over time.

Benefits of RPR®:

  • Traffic Tolerance: RPR® can withstand heavy traffic due to its strong regenerative capabilities. It not only survives high-traffic conditions but thrives under them.
  • Outstanding Recuperative Abilities: If any part of your lawn gets damaged due to traffic, RPR®'s regenerative powers will restore its health and appearance in no time.
  • Resilience: RPR® is not just durable; it's resilient. It can bounce back from pressure, wear, and tear, maintaining its quality and appearance.
  • Spreading Stolons: The determinate stolons of RPR® grow horizontally and spawn new plants identical to their mother, effectively filling in worn areas. This makes it perfect for areas with continuous or extreme traffic.
  • Advanced Breeding Techniques: RPR® is a product of advanced breeding techniques, ensuring it is not just another grass, but a solution to the challenges faced by high-traffic lawns.
