@blue23rose I do not think you have Indian Pumpkin. ?
I grew that for several years and mine had a more crepe like texture.
It is registered as 23" tall, mine never even reached that, stayed more like 18 or so. Yours appears to be taller than that? Your blooms seem to have a more rounder shape, whereas mine was more triangular shaped. It bloomed down in the foliage for me, had sparse blooms, and the flowers melted easily. I had it several years because the color is beautiful but there was nothing else about it to love and I tossed it to the compost-didn't even give it away. Your bloom has a faint eye and Indian Pumpkin does not have that at all. Edit to say that none of the photos of Indian Pumpkin have the green color down at the base of the throat as yours does, and the anthers (I hope I got the right name?) are more heavier black color on your blooms than the other photos.
