Pax Apollo (Dr. N.E. Hansen; R. sempervirens pallida x R. blanda) is another thornless rose. The 2-inch flowers are borned in large clusters and are rose-red passing to amethyst with age. Like other blanda derivatives the foliage is lost early, but the reddening canes minimize this fault. May be used as an arching shrub or short pillar. 6-8' x 6'-8'.

From "Progress in Thornless Roses" by Dr. Niels E. Hansen:
"Pax Apollo Rosa sempervirens pallida x pollen of R. blanda from southern Manitoba. A wonderful producer of deep pink flowers in large clusters in June. Petals about 14. Tall, upright, 7-foot, dark red stems; the wood is smooth; on strong shoots the midrib of the leaf is bristly."
