Whatz up...

Gainesville, FL

...with this Amorphophallus?

Is this an identified type, or is this some weird deal only on this plant? It has come up this way consistently since it was planted 3 years ago. It has snow white tips.

From the petiole it looks to be a Amorpho Bulbifer. Their are a few different clones with different markings but this one looks pretty close to what I have grown as a more common bulbifer.

Then all the others I have must be the uncommon ones, LOL as none of them have the white leaf tips

Sorry was not even paying attention to the white tips. I am not sure if this is environmental or not. If it is consistent it is new to me and maybe a new mutation worthy of naming but if it is sun burn chemical burn or something else then I would say it was a normal Amorpho bulbifer. You may have to wait and see if it returns the following season with the same leaf markings. Or see if it passes it on to the bulbils.

Like I said in the original post, it has come up this way for 3 years now.

The leaflets look the same as my A. bulbifer but the petiole patterns are different. However, no white on any of the leaflets of mine.

Yes it is the only one I have that has this elongated pattern on the stem. I will try to get a better photo of the stem today

Do you leave this in the ground when dormant. Sometimes I've found plants doing wierd things and have found pieces of cement bricks beneath. You have other plants nearby but they're not doing the same. Perhaps move it when dormant, dig the site down to about 1 ft just to see. If nothing add lots of organic material. I'm sure you know if in the ground they prefer to not be wet when dormant.
If the bulbils do the same, name it and get big bucks!

Kalpavriksha,
I do have other plants nearby, but this is the only Amorpho. in that area. I have variegated crinums, variegated and speckled cast iron plants and some gingers planted nearby.

Yes, I do leave them in the ground when dormant, and this is planted in an area out in the part of the property where there is nothing but....sand. Its under the canopy of some small trees. I have 5 acres and only up around the house (pretty far from here) has anything like building materials on it. This area was left largely wild, the ground clutter weeds and briars were cleared but its still wooded.

Its been 3 years and so far this is the lone stranger. It hasn't made any new bulbils. I keep waiting LOL.

Here are a couple close ups of the stem showing the pattern better

If it were me I would try some of the new tubers in another area possibly in pots to see if this keep producing this odd leaf tip variegation. Have you fertilized it regularly? Of course high amounts of Nitrogen and iron can at times cover up even the most stable variegation's, deficiency can cause similar leaf discolorations.

Gainesville, FL

It gets about average fertilizer, which depends on the amount of rain we get. I don;t fertilize as much when its very dry. I'll try it if it makes new tubers, potting them up.

I wouldn;t think a whole lot about this but for two things:

Its come back consistently every year and its very symmetrical in the way its on the leaves. They all have the same amount of the coloration up the leaf the same distance, like its supposed to be there, LOL
