Flowers in interrupted spikes, dark-purple. Fruits are woody ovoid fruit covered in hairs and spines.
Seed collection and propagation
Collect seeds between November and February. Strip seeds off the flower spike that are turning brown using a pair of gloves as the fruits are spiny. Place the seeds in a tray and leave to dry for 1 to 2 weeks. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. From one collection, the seed viability was high, at 90%. Seeds are non-dormant, viable seed should germinate readily.
