The leaves are sessile, lance-shaped with the narrower end towards the base, to narrowly oblong with toothed edges, 20–60 mm (0.79–2.36 in) long and 4–25 mm (0.16–0.98 in) wide. The flowers arranged in racemes or thyrses up to 300 mm (12 in) long, each flower on a peduncle 20–75 mm (0.79–2.95 in) long with leafy bracts 5–10 mm (0.20–0.39 in) long and elliptic to narrowly oblong, toothed bracteoles 10–35 mm (0.39–1.38 in) long. The sepals are linear, 6–16 mm (0.24–0.63 in) long and free from each other. The petals are blue to purple with a yellow throat, 17–30 mm (0.67–1.18 in) long and densely bearded inside. Flowering mainly occurs from August to December, and the fruit is elliptic, warty up to 6 mm (0.24 in) long and hairy.
