Occasionally is a hydrophyte but usually occurs in uplands (non-wetlands).
Glabrous, evergreen or semi-deciduous shrub to c. 7m high. Spines to 2.3 cm long, sometimes single, sometimes 3-partite. Lvs with short petiole to 5 mm long. Lamina up to 7.5 x 2.5 cm, oblanceolate but often very variable on one plant, spiny margins and shining above. Flowers yellow, sometimes with outer parts red-tinged, arranged in simple or compound racemes to 6 cm long. Berry 7-12mm long, broadly ellipsoid to subglobose, reddish black, with an obvious white bloom. Juice dark red with seed about 1mm long.
The combination of large spiny leaves, and 3-partite spines to 2.5 cm long distinguish B. glauccarpa from other berberis species naturalised in New Zealand. It also grows to about 7 m which is much taller than the other species.
