Double Knockout Rose Tree

Double Knock Out® Rose Tree – Classic Elegance with a Twist
With the grace of a rose garden and the ease of a Sunday morning, the Double Knock Out® Rose Tree brings timeless beauty to your landscape—elevated, literally. This tree-form version of the beloved Knock Out® rose features a strong, single trunk and a lush, rounded canopy overflowing with rich, double-petaled blooms. First introduced as part of the Knock Out® family in the early 2000s, this standout variety offers all the flower power with even more charm and structure.

Where It Grows Best
Perfect for USDA zones 5–10, this rose tree thrives in full sun and looks lovely planted near walkways, gates, patios, or as a centerpiece in a cottage-style flower bed. It’s equally happy in a large decorative pot on the porch, offering an upright burst of color all season long.

Growth Pattern
This tree-form rose grows to about 4–5 feet tall with a full, rounded canopy that reaches 3–4 feet wide. The double blooms appear in waves from spring to frost, with little downtime in between. The sturdy trunk supports an abundance of bright flowers—rich red, vibrant pink, or soft blush depending on the variety.

Care Instructions

• Light: Full sun for best blooming (6+ hours daily)

• Water: Deep water once or twice weekly; more during hot, dry spells

• Soil: Well-drained, slightly acidic soil

• Feeding: Fertilize in early spring and again in midsummer with rose-specific food

• Pruning: Lightly shape in early spring before new growth; deadhead for continuous blooms

• Pest/Disease Resistance: Naturally resistant to common rose problems like black spot and mildew

The Double Knock Out® Rose Tree blends the best of both worlds—old-fashioned rose garden beauty and modern, low-maintenance ease. It’s the kind of plant that looks like it’s been blooming beside your grandmother’s porch for years, even if it’s brand new. Full of color, grace, and lasting blooms, it’s a picture-perfect addition to any Southern garden.
