As some of you know .. I love dissecting flowers! Since I have two konjac - I didn't hesitate to dissect the smaller one. Here is a close up look at A. konjack - and it looks like I'm going to get some seeds as the berries(?) are swelling and changing color.

I'm always trying to figure out what evolutionary pressures cause some flowers to grow so differently from traditional flowers.

Like picture 2 - What function does the fiberous material play in the hollow pointed tube above the reproductive parts?

Anne, that is so cool; great photos, you should add a few to the database if you haven't already done so. Voodoo Lily (Amorphophallus konjac)

Nice photos. Are you going to see if you get berries?

Thanks Evan - Yes indeed ... wanting some berries! I thought they might be called berries - thanks for the confirmation. How long does it take for them to ripen?

Last year my first attempts to pollinate were a failure so I can't help. Maybe @Bubbles can.

Speaking of time, would you mind putting a date on your closeup. It will be fun to see how long it takes. This one

I date all my personal photos and record times from pollination to seed maturity like that. I just checked and don't see where I can edit my photo entry .

Being pretty ignorant about Amorphophallus, I'm just assuming once the top of the inflorescent starts to bend over it is no longer receptive. Please correct me if I'm wrong.

Open the photo and at the bottom of the page under ACTIONS select "ยป Edit this image's caption, details, etc."

Generally Amorphs are similar to the Caladium you pollinated. The female flowers exude a clear liquid to capture pollen when receptive. Later the male flowers produce pollen at which point the female flowers are generally no longer receptive (this helps to minimize self-pollination). If the female flowers haven't been fertilized the peduncle will collapse. The spadix appendage in this photo will collapse regardless.

@eclayne I've not tried to pollinate these. I'm still waiting to see mine pop up.

Anne, how are they doing? I think if they're still up you're good to go.

Alas they are collapsing. I was really hoping. But now that I know where the pollen comes from, I'll definitely be helping out the next time I get blooms.

Indeed! It looks like a couple of berries had been fertilized on one but apparently not enough to keep it going.

Evan, here is a picture of the berries. So what happens now? Will foliage grow from the corms or is it done for this years growing season?

It sure looks like a few flowers were fertilized. After flowering I cut off the bloom stalk leaving a few inches then twist the stub off in a few weeks. You may be able to twist it off now. This is supposed to reduce the time to leaf growth. I'll be planting mine in a week or two so you should be OK to plant out now.

Thanks .. I pulled them off as suggested .. no twisting required. They'll go in the ground tomorrow if it ever quits raining.
