Easy Bee-zy Knock Out® Rose carries single bright yellow flowers in clusters, fading to cream as they age, with a light citrus scent. The open single form means bees can reach the pollen easily, which is where the name comes from. Rosa 'SRPylwko' grows 3 to 4 feet tall and 3 feet wide in full sun, hardy from Zone 4 through Zone 11.
Bloom repeats from spring to frost, and yellow is a hard color to hold in a landscape rose since most bleach out entirely by midsummer.
Knock Out roses were bred for disease resistance first. They hold clean foliage through humid summers with no fungicide, bloom continuously without deadheading, and need nothing beyond a hard cutback in early spring. That combination is why they took over the landscape trade.
The habit is bushy and rounded. It won Best Garden Impression Rose at the 2026 American Rose Center International Rose Trials. Cut back by about a third in early spring. Shipped on its own roots.
