HilverdaFlorist has signed a license agreement with Raker-Roberta’s Young Plants to transfer the complete dianthus program from Aris-Green Leaf Plants to Raker-Roberta’s within the next six months.

The partnership between HilverdaFlorist, a Netherlands plant cultivation company, and Raker-Roberta’s, a Michigan custom-grown young plants wholesaler, will continue and secure the production and sales of dianthus cuttings for the North American market.

“Both family-owned companies already have a long-standing and successful relationship together,” said Sjaak Sijm, commercial team lead at HilverdaFlorist. “Our new collaboration will be instrumental, anchored by the production of dianthus cuttings, offering both unrooted and rooted liners through the entire North American broker network.”

Besides dianthus, multiple HilverdaFlorist pot, patio and garden series are already rooted at the Litchfield facilities, Sijm said. This collaboration enables HilverdaFlorist to benefit from the success of Raker-Roberta’s in the U.S. ornamental industry and its distribution network.

“This collaboration reflects our shared commitment to cultivating exceptional quality and introducing impactful varieties,” said Susie Raker, vice president of Raker-Roberta’s. “By strengthening this partnership, we solidify Raker-Roberta’s position as a leader in the perennial industry, driving innovation and excellence forward.”

The availability of the HilverdaFlorist potted dianthus series at Aris-Green Leaf Plants will be guaranteed, with booked orders being supplied until week 40 of 2025. Effective May 2025, Raker-Roberta’s will offer availability for the remainder of 2025, materializing the immediate commencement of the new licensing agreement.

“Together, HilverdaFlorist, Raker-Roberta’s Young Plants and Aris-Green Leaf Plants are committed to ensuring a smooth transition during this period of change,” Raker said.
