  bulbifer bulb
From: taxonomy at verizon.net (Alice Nicolson) on 2007.10.02 at 09:19:19(16373)
Help - I have young Amorphophallus bulbifer plant, grown from seed,
and the current leaf has a bulbil , now about 1 cm, which is now off
the senescent leaf. I assume that I can plant this but don't know
when - immediately or in early spring? - and which end is up? No
particular growing point that I can see - suggestions please!

They seem quite resilient, so don't panic..... I've grown lots and lots of them like this. I would just store it dry along side of the bulb it came off of.... when that bulb starts to grow again, plant the bulbil at the same time. It doesn't matter which way up, it will grow and make it's bulb so that next time you'll look at a normal bulb and will be able to tell...

Alice:

First, it really doesn't matter which surface you put up.? These bulbils do not have a pronounced growing point and, if you what them as they sprout, it can happen just about any place on the surface of the bulbil and I've seen several points green up simultaneously but rather quickly one of them will become apically dominant and the others are just sort of resorbed into the bulbil.

Am. bulbifer can be stored dry and I've even had bulbils as small as the head of a hat pin survive sitting on the shelf.? You can pot it now and not water it or you can drop it on the surface of a little pot of potting medium and watch it.? The last several seasons, I've rounded up the bulbils that are produced and dropped them on the mother plant pot.? That works pretty well and you don't lose them.

I just remove them from the leaf and let them dry well and then store them
dry until late spring when I plant them in potting mix. They always come up.

I'm glad this is so easy for everyone (else). I do have to chime in and say I've never been able to grow one from a bulbil, although I try every year- if I store dry they shrivel up and disappear before spring. If I put them in dirt, the same thing...

Susan,

Last year, I saw my A. dactylifer grew a bulbil at the apex of the
petiole, so I tried an experiment growing it. After the leaf dropped,
I planted the bulbil, but shortly thereafter it had turned
brownish-black when I checked. Fearing that it was starting to rot, I
removed it from the pot, cleaned it, and put it in a covered clear
plastic cup so that I can keep an eye on it. To prevent it from
drying out, I moistened it once in a while. It very slowly
transformed into a tiny tuber with a growing point. After still
sometime, it started to grow roots and that's when I planted it again.

Hiyer, Susan!

I let mine air dry for a day, then I dust them with cinnamon, place them in
egg cartons, and store them in a plastic box. If I put them on the shelf
they do shrivel. If you want to leave them in the soil, they should be
either in a greenhouse, or set the pot on a tray full of damp sand.

At the University greenhouse, A. bulbifer is a weed, dropping bulbils all
over, which come up in pots that they are not supposed to be in.

Good luck,
Christopher
