Shrub Rose 'White Out': Radler's Pure White Knockout

Introduced in 2008 by Bill Radler, 'White Out' (PP20273, also known as Radwhite) adds a pure white chapter to the Radler legacy of indestructible landscape roses. This shrub rose produces clusters of clean, single to semi-double white flowers with a prominent yellow stamen boss, blooming in relentless waves from spring to frost.

Botanical Profile

The plant forms a compact, rounded shrub 3-4 feet tall and wide, with the signature Radler foliage: dark green, glossy, and virtually immune to black spot and powdery mildew. The single-form flowers (5-8 petals) give it a species-rose charm, while the continuous bloom and self-cleaning habit are pure modern breeding. White roses are notoriously difficult to breed for disease resistance—Radler's achievement with 'White Out' is significant. It's a white rose you can plant and forget, emerging each spring with a fresh canvas of pure blooms.
