Homeowner Growing & Maintenance Tips

Double Knock Out is more floriferous than Knock Out and raises the bar with petal counts of 18-25, twice the number of Knock Out. It is covered with fuller, richer, cherry-red blossoms that are simply breathtaking. Blooms maintain a continuous show of color from mid-spring to frost with beautiful foliage almost year-round. Double Knock Out presents itself in a fuller, more compact fashion than Knock Out and offers enhancements in Knock Out's easy to care for qualities of disease/pest resistance and drought/humidity tolerance. Also, Double Knock Out is more winter hardy and shade tolerant than its predecessor. Along with eye-catching beauty and superior performance, it offers wonderful flexibility in use. Double Knock Out works wonders in abundance, by itself, or in tandem with your favorite perennials and annuals!

Thrives in humid climates without spraying.
