  Real name for an Amorphophallus
From: Lester Kallus <lkallus at earthlink.net> on 2018.10.18 at 06:28:38(24096)
I initially posted to the Amorphophallus group on Facebook but see
little traffic there so will try again here.

Despite my initial plans
to avoid once again increasing my collection while attending the
2018 IAS Show & Sale, I could not resist during the auction
when an Amorphophallus came up for bid. It was jokingly called
“Mary Jane”. The label was blurry. Searching the web, it seems
closest to a Madagascar species: A. mahajanga. I bid and won.

It grew well for a
couple weeks but overnight during a minimally (and early) cool
snap here on Long Island (50F/10C), collapsed into dormancy.

I’ve pulled up the tuber
and it looks fine, just
dormant. There had been two petioles but they appear to have
been growing out of this one small tuber. I haven't formally
measured it but would guess 5-6 mm in diameter.

I've done a
bit of web searching but have yet to find growing advice. If
this truly is Am. mahajanga can someone please advise winter
storage? Is it one that can be allowed to become totally dry or
must I keep it in moist sphagnum until the next growing season?

Hiyer, Lester!

Good to 'hear' from you!

I have a couple of Subsaharan African species, but no direct information on A. mahajanga. However. all the species I have had like to be bone dry and cool (70 degrees F, 21 degrees C) during dormancy. When they are up and active they want to be hot with bright indirect light. When I say hot they do best around 90F, 30C. Remember, most of Madagascar is seasonally dry.

I hope that it works for you. It sounds like a nice species.

Happy days,

Thanks Ron & Christopher. So, dry it will be. Yes, I'll have no
difficulty keeping it in those conditions. While still here on Long
Island, I will have my 2nd floor greenhouse which will be kept roughly
70 over the winter. I'll just keep it on a shelf away from areas that
are watered.

I should have taken close-up photos, but did not expect the premature
collapse. What I recall was the brilliant vermilion color where the
leaflet attached to the petiole. I've seen that same vermilion in some
(and only some) of the available Google images. I'm assuming that will
be controllable by the amount of sun I give it next growing season. The
color contrast in the leaflet and marbleized petiole may be what made
"Mary Jane" an appropriate nick name.
