Plant description

Annual, parasitic plant with yellow or red thread-like stems, twining and attached to the host plant. Once attached to a host, the stem decays near the base and severs connection to the root. Leaves reduced to small scales. Inflorescent in clusters of 2-5 golden yellow flowers. Flowering between December and May. Fruits are orange depressed-globular capsule to 3.8 mm diameter. Seed embryo type is folded.

Seed collection and propagation

Collect seeds between January and June. Collect capsules that are maturing, turning brown and contain hard seeds inside. Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules gently by hand or with a rubber bung 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.
