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.
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.
is good. We grow one plant on the
crevice bed in full sun and it grows
to approx. 15cm (6”) tall. Another
plant is in a slightly shaded bed with
richer soil and grows to approx.
20-25cm (8-10”) and seeds well.
