White Knock Out® Rose Bush

Effortless, spring through fall white blooms that brighten your landscape

The White Knock Our® Rose bush offers fragrant blooms in an easy-to-grow compact form

What makes the White Knock Out Rose unique?

This selection stands out for the striking contrast between pure white, lightly fragrant single blooms and matte, near‑black new foliage on a dense mound that matures around 2–4 feet tall and wide; perfect for low hedges or mass plantings that won’t overwhelm small spaces. It’s also a decorated garden workhorse, earning the 2011 multiple landscaping and horticultural awards; independent proof that it looks good and lasts in real yards.

Why you’ll love it

You’ll get continuous color from spring to frost without routine deadheading thanks to self‑cleaning blooms, plus reliable resistance to black spot, rust, and powdery mildew that keeps foliage handsome through summer’s humidity. The flowers carry a light, pleasant fragrance that is never overpowering. This make is ideal for planting near porch seating. Hardy from USDA Zones 4–11, it thrives in full sun and everyday garden conditions, making it a confident choice whether you’re refreshing a front border or creating a moon‑garden glow in evening light.

How to Grow White Knock Out Roses

Choose a full‑sun location (at least 6–8 hours). Dig a hole slightly wider than the pot, loosen the roots, and plant so the crown is level with the surrounding soil. Backfill, water deeply, and mulch 2–3 inches, keeping mulch a couple of inches away from the canes. Space plants about 3–4 feet on-center for a seamless low hedge. Keep soil evenly moist the first season, then water about 1–2 inches per week during dry spells, directing water at the base to keep foliage dry. Prune once a year in late winter or very early spring as new shoots appear. Cutting back to roughly 12–18 inches helps maintain a neat 3–4 ft mound by season’s end and encourages vigorous new growth. If you choose to fertilize, wait until after the first flush of blooms and use a balanced rose food per label directions; avoid late‑season feeding so new growth can harden before winter. In very cold zones, add a winter mulch blanket; in containers, choose a pot with drainage and refresh water more frequently in heat.

• For families and pollinator lovers, there’s more good news: Knock Out® roses are non‑toxic to people and pets and their open, single flowers are accessible to bees and butterflies! They are a lovely way to add life to your landscape while keeping it low‑maintenance.
