Sunny Knock Out® Rose, Rosa 'RADsunny' (PPAF), produces abundant single 3 inch wide bright yellow flowers with 5 to 6 petals. This bushy, compact and rounded shrub has dark green semi-glossy foliage, resistant to black spot, powdery mildew and rust. More disease resistant that its famous parent and grows to 3 foot high and wide. No flower fragrance, but the petioles release a strong sweetbriar fragrance similar to Rainbow Knock Out®. Sunny Knock Out is easy to grow and adapts to most conditions. Prefers slightly acidic soils. It thrives in very humid climates where other roses have disease problems and need spray maintenance. Feed once a year with a slow release fertilizer.
