Name derivation:
Blennodia from the Greek 'blennos' meaning slime; referring to the mucous seeds. Canescens from the Latin 'canescens' meaning becoming grey; referring to the greyish appearance of the plant.

Plant description:
Erect annual herb to 50 cm tall with hairy stems and branches. Leaves pinate with 2-5 pairs of lobes, to 12 cm long, reducing towards the apex. Flowers white, pink or lavender on a long spike. Flowering between July and September.
Fruit type:
Long brown cylindrical pods held erect along the stem. This differ from Blennodia pterosperma where the pods are hanging down.
Embryo type:
Bent.
Seed collecting:
Collect pods that are maturing, drying off and turning brown with yellow seeds inside.
Seed cleaning:
Place the pods in a tray and cover with paper to prevent seeds from popping out and leave to dry for a week. Then rub the pods gently by hand 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.
Seed viability:
From one collection, the seed viability was high, at 85%.
Seed germination:
This species has physiological dormancy that need to be overcome for the seed to germinate.
