Crinodendron hookerianum is a shrub or small tree with ash-grey bark reaching up to 8 metres (26 ft) in height and having a trunk up to 30 centimetres (12 in) in diameter. Leaves alternate, lanceolate with toothed edges and acute apex, petiolate, 4–7 cm long and 0.7-1.8 cm wide, dark green above and hairy whitish green below. Flowers hermaphrodite, solitary and axillary, pinkish to red. pedicels circa 3–6 cm long, the calyx formed of 5 fused, green sepals, corolla campanulate, composed of 5 free petals terminating in 3 teeth, stamens 15-18, the style longer than the stamen. Fruit a white, pubescent, leathery capsule with 3 to 5 valves. Seeds ovoid, glossy.
Crinodendron hookerianum will only thrive in colder areas in a sheltered woodland garden or against a south-facing or west-facing wall, tolerating an exposed site only in mild areas. It can also make a fitting subject for the cool greenhouse or conservatory, under which conditions it will flower earlier. It is hardy to -7 °C. It should be grown in fertile, moist but well-drained, humus-rich, acid soil in partial shade (in full sun only if the roots can be kept cool and shaded). It should be sheltered from cold, drying winds. Young growth and flower buds are susceptible to damage by hard frosts - the latter especially so, owing to the plants unusual behaviour in producing small flower buds in Autumn which ripen gradually into the mature flowers of the following Summer. Although the only pruning generally required in colder areas is the removal of dead wood in late Spring, in milder areas in a light woodland environment it can even be clipped to make a wind-break. Vegetative propagation is by greenwood cuttings in early Summer or semi-ripe-wood cuttings in late Summer. With regard to pests and diseases the plant is generally trouble-free. Maximum dimensions in cultivation approximately 8m in height by 5m in spread.
