Re: Amorphophallus myosuroides
Erin and others that might be growing Am. myosuroides and Am. ongsakulii...
Both these species tend to send up multiple leaves as well as multiple flowers
during the growing season. Also both these species tend to produce anywhere
from 7 to 14 offsets during the growing season. Towards the end of the growing
season the offsets begin to send up leaves that can be almost as large as the
parent tuber's leaf. This aspect of leaf growth (parent tuber's leaf going
offset's new leaf emerging) makes it somewhat difficult to determine if the
is going dormant or starting an immediate second growth cycle.
If you continue to keep the pot moist, the offsets will continue to grow. I've
growing these 2 species for 5 years and I stop watering them about now and force
them to go dormant. I've never experimented with watering them throughout the
so I don't know if continuous watering would put them in the 'pseudo-evergreen'
