Research & Development

Testing and evaluation of all Star® Roses and Plants continues to expand as we upgrade and develop newer and more rigorous methods to ensure the excellence of all plants we introduce.

Over the years we have introduced many award winning plants including The Meserve Hollies and more than 30 varieties that have received the All American Rose Selection Award. Those include the first for a miniature rose (Debut™), and the first for a landscape rose (Bonica®). More recent winners include The Knock Out® Rose and Sunshine Daydream, the first Grandiflora to win this coveted award under no-spray testing conditions. Additionally, Francis Meilland® was the only Hybrid Tea to win the AARS award under these no-spray trials.

Since our founding, our philosophy when introducing new plants has been based on two principles. First, we maintain very close relationships with hybridizers who entrust us to evaluate their seedlings. Second, we maintain a superior testing facility to ensure that only the best plants are introduced. 

Star® Roses and Plants works with well-known and amateur hybridizers to introduce their plants to the market. This commitment goes back to the mid- 1930’s when Conard-Pyle partnered with Meilland International, and with Kathleen Meserve, who single-handedly redefined what Hollies are in North American gar­dens. Those enduring relationships, as well as more recent ones with Will Radler, the breeder of The Knock Out® Rose and Jim Sproul, creator of Eyeconic® Roses, break­through hybrid Hulthemia roses, highlight our commitment to bring new and excit­ing plants to market.

We operate full testing facilities on both the East and West coasts. Roses must per­form well in our three locations in order to be introduced to market. We also con­duct extensive production trials to make sure that each new potential introduction performs well on its own roots, in containers as well as in the garden. We evaluate our new peren­nials and woody plants along a similar rigorous evaluation process. This sets a very high standard that is unmatched in the industry.
