It blooms more than any other rose. It's self-cleaning, and it blooms later in the season, probably than any other rose before it," Radler said.While people exchange bouquets of roses for Valentine's Day as symbols of love and commitment, Radler sees a deeper meaning in his creation."They give a bouquet of roses out, and it lasts for a week. Maybe a little bit longer, but if you plant a bush, it can last for years. The original plant of Knock Out is 30-some years old," Radler said.Radler's journey began when he was just 9 years old and discovered his love for flowers and planting roses. However, he never imagined where that childhood passion would lead him. "Absolutely not. My biggest dream was that I would have a few roses that might be introduced to the market. I just never thought they'd be this popular," Radler said.The Knock Out rose has become one of the most successful rose varieties ever created, bringing beauty and lasting love to gardens worldwide - a fitting legacy for a flower associated with romance.Its about time to watch on your time.
