Last year, more than 2,000 people visited the Raker Trial Gardens. Predominantly from the Midwest, this collection of professionals is a representative cross-section of the horticulture industry; including, greenhouse owners, landscape designers and professionals, industry brokerages and sales representatives, trade writers, and most importantly, home gardeners.

For the last nine years, the Raker Trial Gardens have been a destination for the horticulture industry – and this year is no different. In addition to expanding every aspect of our comparison trials (row, hanging basket, and large container) we are continually expanding our trial services to include additional types of research and genetic evaluation.

The Trials are an extension of our in-house Research & Development Team. Led by Dr. Paul Karlovich, the Team routinely conducts evaluation / trial projects focusing on internal production and breeder / university research.

Our partnership with Hort Couture™ has afforded Raker the enviable task of providing an independent, objective evaluation and trial process for breeders to introduce genetics into the North American Market. Our goals are to partner with independent breeders, and together, lead the industry in launching solid, new genetics into the independent channel.

We provide a confidential and objective trialing site for the independent breeder. All samples submitted are evaluated under greenhouse and field settings from both propagation and finish perspectives. Our rigorous testing process ensures that selected genetics perform optimally for the grower and the end-consumer.

C. Raker & Sons, Inc. is the leading commercial wholesaler of custom-grown plugs and liners in North America. Through both seed and vegetative propagation, Raker supplies more than 3,000 unique plant varieties to greenhouses and nurseries around the planet.

In addition to growing the highest quality product, Raker provides unmatched value-added service and selection at competitive prices. In 1978, Raker was established on this basic ideal, and we are proud to continue this standard today.

Structured to meet the needs and requirements of small- and medium-sized growers, Raker offers a range of features unrivaled in the horticulture industry:

If you wish to order one tray, Raker will ship you one tray. This applies any time of year and for any product. No need to fill a box, fill a pallet, or fill a truck, we simply want to fill your order. Raker exists for small- and medium-sized growers.

Our quoted price is our bottom line. Whether the price quoted is delivered or freight-on-board, Raker never adds-on royalty, boxing, handling, or fuel charges.

Preparation is vital to success. Raker rewards readiness with two discounts that apply regardless of the season: Early Order and Volume. Early Order provides a 10% discount on any order placed 12 weeks before the ship date. Volume rewards an automatic discount between 8-33% (depending on your order history).

Always submit your order to Raker for a competitive bid. Our pricing structure is intricate to provide small and medium-sized growers with the best possible price on plugs and liners. This service is no charge to you and ensures you are getting the best price.

Raker is a simple solution for your plant tag purchases. If tags are not provided as part of a patent, let us know and we will deliver them with your plants. Our small bundle sizes (and delivery savings) make ordering tags from Raker a smart choice.

We primarily grow product in 6 tray sizes (3 plug & 3 liner trays). In addition to these standard tray sizes, we have the ability to grow product in another 24 sizes.

In addition to the plant varieties we list, a Raker specialty is custom growing. Once a custom is approved, the minimum for seed items is only 3 trays and vegetative items is only 200 cuttings.

 In addition to custom-grown items, we maintain an extensive “at-once” inventory.  Our real-time inventory management system ensures trays ordered online ( are truly in-stock. When you order a tray from Raker Availability / Speculation, you will receive that tray (not a substitute).

Raker ships directly to your greenhouse. Our tried-and-true packaging delivers high-quality plants intact and ready-to-grow. Additionally, a 50-tray order qualifies for private (grower) delivery, or we will place your order on our patented shipping cradle system. Plant products ship via FedEx, UPS, and Air. Or, stop by our facility and pick up your order.

All Raker orders route through our network of 35 broker offices. This network completely covers North America – for a list of brokers, please contact us.

If you ever have questions or concerns regarding your plant products, please feel free to contact Raker. We believe open communication is key to a successful business relationship.
