Star Roses and Plants announced that National Knock Out Rose Day is now an officially recognized date by National Day Calendar. It will occur every year annually on the Friday before Mother’s Day, which this year is May 9, 2025.

The decision to create a national day was made as part of the celebrations surrounding the 25th anniversary of Knock Out. From nearly 30,000 annual submissions, only about 20 are chosen by National Day Calendar.

“The Knock Out rose has become so recognizable over the last 25 years, we knew we wanted to try to get it nationally recognized with its own day, and we’re thrilled that it was selected,” said Susan Bacus Morgan, marketing manager for Star Roses and Plants.

Independent garden centers and online retailers that sell Knock Out roses are invited to participate in celebrating National Knock Out Rose Day on May 9 and through the entirety of the spring season. Star Roses and Plants has several free, ready-made options available.

Retailers can order free point-of-purchase materials that are specially designed for the 25th anniversary of the Knock Out brand by visiting the Star Roses and Plants online storefront. Hi-res images, social media graphics and copy content are also available to download as part of the brand’s e-retailer asset library.
