Rosa 'Radcor' Rainbow Knockout® grandiflora rose blooms from mid-June until the first frost, producing five-petaled flowers of coral pink with a yellow center. The new foliage is burgundy and ages to a deep green. Hips (rose fruit) are produced in fall and carry over into winter. This rose is among the most resistant to diseases of any rose cultivar. Plant it in moderately fertile moist soils with plenty of room between it and the neighboring plants to provide for good air circulation.
