Seeds are dark-brown to black ovoid seed 2-3 mm long with a white aril. Seed embryo type is spathulate

Seed collection and propagation

Collect seeds between July and December. Collect capsules that are maturing, drying and turning pale green with dark seeds inside. Keep an eye on the capsules, as they can ripen and split open quickly. Place the capsules in a tray and cover with paper to prevent seeds popping out and leave to dry for a week. Then rub the capsules gently with your hands to dislodge the seeds. Use a sieve to separate the unwanted material. 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.

The collections and germination research being undertaken on this species is supported by the Murray Mallee Local Action Planning Association (MMLAP) and the East Murray Area School. www.malleefutures.org.au

The SA Seed Conservation Centre recently collected 8,000+ seeds for this species for upcoming germination research in early 2018. Plants propagated from this research will be utilised in local projects, included a Seed Production Area in the region and a germination protocol will be made available on this webpage.
