RULES & CONDITIONS

The International Rose Trial in Shreveport. LA was established in 2019 and approved by the World Federation of Rose Societies in 2023.  The Trials are open to all professional and amateur breeders across the world with the distinct purpose of evaluating the performance of varieties in Zone 8 growing conditions and comparing the growth and flowering characteristics with similar new introductions provided by breeders. The Trials are conducted under the guidelines set forth by the World Federation of Rose Societies.  

The roses are cared for in accordance with modern methods of garden culture using environmentally friendly products, and judged not only for the beauty of the flower but equally for their disease resistance, fragrance and overall aesthetic plant appearance. 

The ARC Trials affords breeders a stage to display their work and receive feedback on the performance of their roses.  Two unique logos are designed to recognize award winning roses:  one will recognize Gold Medal Award winners, the other will recognize all other ARC Rose Trial Awards.  Breeders and Nurserymen will be granted limited rights to use the American Rose Center Rose Trial logos in marketing and promotions of their winning varieties.
