Amorphophallus philippinisis and A. palawanisis
1. The Araceae family
of plants
What is an Aroid?
Aroid is the common name for members of
the Araceae family of plants, sometimes
known as the Philodendron or Arum family.
The occasionally beautiful and often bizarre
combination of spathe and spadix called the
inflorescence, sometimes referred to as a
"flower", is a distinguishing feature of all
aroids.
8. Note the withered appendix at the top of the
infructescence. The berries ripen from the top
downward. Amorphophallus seed should be
planted very shortly after ripening as they lose
their viability very quickly if stored dry.

30. Amorphophallus paeoniifolius may be seen growing in full sun where surrounding vegetation
has been cleared but is usually found in semi-shade where vegetation has a relatively open
under-story. It tolerates less drainage than most other Amorphophallus. In cultivation it can
grow in any fertile soil and grows well in mixes of sand, rice husks or wood shavings. In Bali it
often grows beneath coconut palms or stands of bamboo in clay that dries and cracks for 8
months of the year so that the plant completely disappears for the dry season. In the wet
season from early December to April A. paeoniifolius appears and flowers late October to early
November, producing a leaf directly afterward. By late April as rains cease the leaf turns yellow
with only a few hardy plants seen in leaf by June.
A. paeoniifolius is a “classic” Group I Amorphophallus and tubers should be stored dry when
dormant.
