  Amorphophallus Titanum offset?
From: Jason Sarine <jasondsarine at hotmail.com> on 2011.01.22 at 17:46:56(21794)
Well here is some food for thought. I dug up one of my titanums that was going dormant to repot today and imagine my surprise when I found a second smaller tuber alongside the main one. It had a small second leaf all summer but I imagined it was just feeding the main tuber as I thought they did not divide or offset, but here we are.  Now I pose this question. The seller I bought these from grows their stock from seed. Could some genetic diversity have actually created an offsetting titantum? I guess another growing season is in order to see if it holds this trait.  Bye now.

An even worse answer is that you may have bought the wrong species...................... Any pics available on the plant in leaf?

Cheers,

Jason, This is not that unusual as you will likely here from others here. Mine have done it multiple times, in fact one of mine has 2 extra leaves at the side of the main growth now that just went dormant so unless momma consumes them if they are still attached I will have 3 rather than 1 when I unpot. Good luck with yours,

Dan

The question is, where did you get the tuber? I've read a lot of controversy about some sellers selling "fake" titanums. I get mine from Tindara Orchids which is a very reputable seller.

All of mine had multiple leaves, but have not dug them up yet - maybe I'll find some offsets too? Who knows!

At least two of our titanums have split into two corms - one that we
still have and one that we donated to the Marjorie McNeely Conservatory
in St. Paul, Minnesota. These plants are all grown from seeds from
the original Symon collection.

I bought one of your titans from you on eBay Jude. The extra leaf was just feeding the same corm and eventually fell off.. At one point in time, I had over 100 titans that I bought from EGF Orchids. It was like $50 for 10 of them. I waited for them to go dormant and sold the dormant corms and made a killing on them. I would start bidding at 99 cents and they would often got up to $70-$80. My best customers were from Europe but I digress. What Im getting at is out of those that had 2 leaves none of them had off sets. HOWEVER a few did end up having 2 corms growing in the same pot! The seeds in those cases grew to be twins was the explanation I was given as there was supposed to be only 1 seed per pot. My seeds were collected from a wild population in their native country. At the time I did it, It was just a money making venture so I sold them all.

I refuse to participate in the recession,

I too, have had A.titanum produce offset tubers below ground. My experience is that young seedlings will produce multiple leaves, but they are in succession, as the old leaf is starting to die, the new leaf is replacing it. This does not result in division of the tuber. But, anytime you have more than one leaf on a tuber of reasonable size, it means you will have a tuber for each leaf when you dig the plant up after leaf death. I have seen 3, even 4.

Will also mention that producing clonal tubercles of titanum is pretty easy using leaflet cuttings.

Hi Bernhard,

One of the plants that we donated to the Marjorie McNeely Conservatory at
Como Park in St. Paul had two leaves on it at the time. When they
unpotted it after dormancy set in, there were two corms, one smaller than
the other. The larger one, BOB flowered, then died from the effort
(the inflorescence was small and distorted, and the plant apparently went
into the flowering stage too early). The second separate clone
(BOB, too - not the second corm of the first clone) might flower within
the next few months (it's dormant now, after producing a large leaf that
lasted for over a year).

Here are links for some photos:
