Amorphophallus konjac

The biggest konjac tuber of 2006, which is the same plant seen at the left in the
blue tub, weighed 23 pounds, smashing my previous record by 6 pounds!
At left is a photo of me with Amorphophallus konjacs from Summer 2005.
The largest plant is of unknown age, but flowered for the third time in April '05. I'm guessing 8 or 9 seasons old. Corm
was approx. 17 pounds when planted, officially 16 pounds when exhumed in '05 and 23 pounds when exhumed in '06.
The second largest plant (in the black bucket) is also of unknown age, but is likely one season younger. It weighed 12 pounds
when exhumed in '05.
The third largest plant (green pot) is in it's fourth or fifth season of growth.

The small plant, front left, is in its third season of growth, and was one of my offsets from 2002.
The small plant, front middle, is in its second season of growth, and was one of my offsets from 2003.
The plant I'm holding is in its first season and was an offset from 2004 when planted in Spring 2005.

Amorphophallus albus
(aroid.org's
A. albus page)
I don't have any of my own photos of A. albus. Please refer to the International Aroid Society's web page, which contains
excellent photos by Wilbert Hetterscheid.
A. albus are very easy to grow, treat them like a konjac or bulbifer; they break dormancy at about the same time for me.
This is a very nice plant that stays a friendly size for those of you who are tight on space. With a maximum height of about
20 inches they won't take over the way konjac, paeoniifolius and some of the other large species can! The petiole of A.
albus is often solid green in young plants, but after a couple of years will display darker green spots on the lower portion.
When the tubers are lifted in the fall it will remind you of a nest of snakes because of all the offsets!

Amorphophallus atroviridis 'Midnight'
(aroid.org's
A. atroviridis page)
|
(Click picture for larger image)
|
The 'Midnight' form of Amorph. atroviridis has a beautiful dark reddish to milk chocolate brown petiole, sometimes solid
color, sometimes with lighter spots, and the dark leaflets have a thin red edge. Abosolutely stunning! If you don't have
this form of A. atroviridis then you need it.
'Midnight' is not an officially recognized cultivar name, it's just the way my supplier had them labelled. But it's a fitting
way to describe the plant so I'm sticking with it.

Amorphophallus henryi
(aroid.org's
A. henryi page)
It's a rare occasion that I find myself without much to say, but here we are...
I planted a bunch of henryi offsets and now I have tubers. Foliage and petiole-wise
they were nice, fairly generic Amorphophallus plants. The inflorescence is quite
another story. Please see the link at the top to the IAS's Am. henryi page.

Amorphophallus koratensis
(aroid.org's
A. koratensis page)
Aroideana vol. 19 says, "The tuber is best left in the soil during resting." In my experience
the soil should be allowed to dry out. If you give too much water during dormancy you risk rotting the tuber.
Amorphophallus koratensis is a lot more interesting than I first thought the first year I grew it. My plants in 2004 were
really beautiful, all with dark, bumpy petiole with light markings - I loved it! In 2005 I grew about 90 or
so, all the really small tubers that I got the previous fall and didn't want to sell because of the small size.
What I discovered is that the plant is amazingly variable. I have some light green with white markings; I have some medium
green with lighter markings; I have some really dark ones with light markings. I have bumpy petioles and I have almost smooth
petioles. I have one plant (only!) that is solid light green, no spots at all! Most of the small tubers are producing
a second and even a third leaf - those will put on extra size over the ones that only have one leaf.
The best part about plants that display so much variability is that one is never enough! I've divided the petiole colors
into roughly green/smooth, green/bumpy, dark/smooth, dark/bumpy. Doesn't that mean that everyone needs at least four? Then
what about the extreme ones? Very very bumpy, or solid green? I think everyone needs more than four!

I don't have any of my own photos of A. longituberosus. Please refer to the International Aroid Society's web page, which
contains excellent photos by Wilbert Hetterscheid and David Scherberich.
Aroideana vol. 19 says, "The tuber becomes susceptible to rot in the final stages of the growing season
and watering must then be minimized."
You'll need a deep pot for these guys!

Amorphophallus pygmaeus
(aroid.org's
A. pygmaeus page)
01-240x160.jpg)
02-240x358.jpg)
Aroideana vol. 19 says, "Grow in an average, rich soil. The tuber can be stored dry during resting."
The leaf of this plant is a deep green on top and reddish/purplish on the bottom. Normal species variation may yield differences,
of course. It's a diminutive plant that easily fits into any collection, no matter how crowded, and makes a splash bigger
than its size thanks to the interesting coloration.
The photos are of a display of Am. pygmaeus that Scott Hyndman entered in the 2006 IAS Show & Sale. He had a mixture of
plants in leaf and bloom and you can see that he won a first-place ribbon.
If you click on the photos you'll see larger versions.

Amorphophallus sp. 2008-01
The leaf of this plant is very much like Am. linearis in that the leaflets are very thin.
The plant itself is of a smallish size, probably not over 18" tall.
The tubers are quite long and very skinny. They're no bigger around than a pencil and
in most cases they're more slender than that. These will need a deep pot to grow in, like
Am. longituberosus. I don't know if they produce offsets. They can probably be stored
dry, but because of the slender nature of the tuber my personal choice will be to store
them in dry soil.
