About
Roundway Titan' is an erect, sturdy, evergreen shrub to 1m tall and 1.65m across. Honey-scented, yellow-green flowers are produced from late spring to late summer, turning pale brown as they age, followed by yellow-green, berry-like fruit. The foliage is yellow-green with a pale midrib, and often produces vivid red tones in autumn and winter.
