We purchased two pots of Arisaema seed at a plant stall a number of years ago; one pot had a label Arisaema jacquemontii but the other no label. Both pots germinated. When they eventually flowered we had jacquemontii and the other was flavum.

Arisaema flavum is a small species widespread across eastern Africa and southern Asia. It has greenish yellow to bright yellow spathes, 2-4cm long held level or just above the foliage, which are borne in summer, followed by green berries turning red in autumn, which we sow beside the parent plant.
