Plant description
Annual herb to 60 cm high with one to usually several erect stems from the basal rosette, with a tap root, covered with spreading to appressed hairs. Leaves densely clustered, oblanceolate, subpetiolate but with a short sheath in the basal rosette; becoming widely spaced, lanceolate and sessile below the inflorescence, to 25 cm long and 4 cm wide; pointed, rarely with undulate margins. Flower-spike terminal with pedicellate funnel-shaped, blue flowers. Flowering between July and November. Fruits are brown fruit cluster with up to four seeds hanging along fruiting spike. Seeds are brown ovoid to globose seed to 4 mm long and 2.5 mm wide covered in barbed spines to most of the surface. Seed embryo type is spatulate fully developed.
Seed collection and propagation
Collect seeds between December and February. Collect maturing fruits, those turning brown and contain a hard seed inside, by running your hands along the fruiting spike or break off the whole spike. Wear gloves as fruits can be prickly. Place the seeds/spikes in a tray and leave to dry for two weeks. No further cleaning is required if only seed collected. If seed spikes collected, use hand to strip off the mature seeds. 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. Seed viability is usually high. Seeds are non-dormant, viable seed should germinate readily.
