The cat's claw creeper Dolichandra (syn. Macfadyena) unguis-cati is an invasive evergreen climber, climbing as high as 9m with claw-like tendrils between the bright green oblong to lance-shaped leaves, which have a terminal, three-part, claw-like tendril. The bright yellow flowers appear from September to February and are trumpet-shaped, occurring in clusters of two or three, sometimes solitary. Flattened, brown leathery capsules hold the winged, papery seeds. This climber invades forest margins, woodlands, plantations, roadsides and urban open spaces.

Chinese sagewood is most vigorous in well-drained soil and full sun. It can tolerate drought and low nutrient soil and can grow in very challenging conditions, such as cracks in the pavement and along railroads. Seeds require exposed soil to germinate successfully and seedlings are not often seen in improved garden soils or well-maintained landscapes.
