@Swayback This flower is from an Amorphophallus paeoniifolius. The bulb was about 7 inches diameter early this spring. It had split the pot it was in and l repotted the bulb into a 15 inch diameter plastic pot. I wasn't expecting it to bloom this year, because it was about 5 inches diameter when l bought it last spring. I have 4 plants and l can see babies coming up next to the main stem of 2 of 3 that are too small to bloom. lf they are large enough this fall l'll cut them off the main bulb early next spring and pot them separately.
I fertilize regularly. This year l am using Hasta Gro plant food.( Last year l used Miracle Gro.) Lots of sun and water, maybe a little bit of shade in July and August.
I do not have experience with A. konjac or any other Amorphophallus.
But it looks like you are doing a great job growing them.
