Fully double, cherry-red blooms cover the plant from spring until the first hard frost, with no deadheading required to keep the flowers coming. It’s dramatically more disease-resistant than traditional roses, drought-tolerant once established, and requires a fraction of the maintenance of classic hybrid teas. If you’ve ever given up on roses, this is the one that will change your mind.\u003c\/p\u003e\u003ch3\u003eWhy Double Knock Out® Outperforms Other Roses\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous blooming spring to frost\u003c\/strong\u003e — reblooms in flushes every 5–6 weeks without deadheading; one of the longest bloom seasons of any shrub rose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFully double flowers\u003c\/strong\u003e — lush, multi-petaled cherry-red blooms with a light, pleasant fragrance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExceptional disease resistance\u003c\/strong\u003e — highly resistant to black spot, powdery mildew, and other common rose diseases that plague traditional varieties\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrought-tolerant once established\u003c\/strong\u003e — far more resilient in dry conditions than hybrid tea roses\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-cleaning\u003c\/strong\u003e — spent blooms drop cleanly without deadheading, keeping the plant tidy and encouraging the next flush\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePollinator magnet\u003c\/strong\u003e — attracts butterflies, bees, and beneficial insects throughout the bloom season\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile landscape use\u003c\/strong\u003e — works as a specimen, mass planting, low hedge, border accent, or container plant\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHardiness \u0026amp; Growing Zones\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSDA Hardiness Zones:\u003c\/strong\u003e 5–9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZones 5–6:\u003c\/strong\u003e Hardy in-ground; may die back partially in harsh winters but regrows vigorously from the crown in spring; mulch heavily around the base before first frost\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZones 7–8:\u003c\/strong\u003e Ideal conditions; vigorous growth with prolific, continuous blooming from spring through fall\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZone 9:\u003c\/strong\u003e Thrives in heat; may experience a brief summer slowdown in the hottest periods, then rebounds with a strong fall bloom flush\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSunlight:\u003c\/strong\u003e Full sun (6+ hours required; 8+ hours for best bloom production and disease resistance)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoil:\u003c\/strong\u003e Well-drained, slightly acidic (pH 6.0–6.5); adaptable to most soil types with good drainage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMature size:\u003c\/strong\u003e 3–4 ft tall × 3–4 ft wide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBloom time:\u003c\/strong\u003e Spring through first hard frost (April–November in most zones)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePlanting \u0026amp; Care Tips\u003c\/h3\u003e\u003cp\u003ePlant in the sunniest spot available with good air circulation — air flow helps prevent the few disease issues this rose can encounter. Water deeply during the first growing season to establish roots, then reduce frequency. Fertilize in early spring with a rose-specific or balanced slow-release fertilizer; a second application in midsummer encourages a strong fall bloom flush. Prune in late winter or early spring before new growth emerges — cut back by one-third to one-half to encourage vigorous new growth and the largest bloom display. No deadheading required, but removing spent clusters can slightly accelerate the next flush.\u003c\/p\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1 Gallon (Single)\u003c\/strong\u003e — most economical; great for mass planting projects\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1 Gallon (2-Pack)\u003c\/strong\u003e — two plants at a value price; ideal for borders or hedges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2 Gallon (Single)\u003c\/strong\u003e — well-established root system; faster to first bloom\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3 Gallon (Single)\u003c\/strong\u003e — most established size; may bloom first season after planting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3 Gallon (2-Pack)\u003c\/strong\u003e — two large plants; best value for immediate landscape impact\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1–2 ft.
