Do you mean the erect white part or both that and the green peeled-back part? The white is the spadix, with the male or pollen-bearing 'flowers' on the top portion and the females on the bottom (where else do women belong?) Actually, in plants it makes sense, as the pollen falls down on the the females below. In some cases the females don't mature until after the pollen has dried and blown away (or been removed by the hybridizer or other pollinator) so that pollination by another individual is ensured. The green curled-back portion is the spathe, and that combination is what defines an aroid--spathe and spadix inflorescence. But I don't know what your plant is specifically.

I got home last night and here is what has bloomed from my Lowes specials. 2 of the 3 aphrodite have bloomed and both are aphrodite( just beautiful). Of the 3 minerva 2 have bloomed one is a orange soverign, and the other was apple blossom. Of the 3 Apple Blossoms, 1 has bloomed it was Apple Blossom. Of the 3 Vera, one has bloomed and it was Vera, of the 3 Lady Jane, one has bloomed and it was Lady Jane, of the 6 susan, 1 has bloomed and it was Lady Jane, of the 6 Prince Carnivals, 1 has bloomed , I have no idea what it is. The stem is very tall over 20 inches it towers over the other plants. It is dark red, with a small white throat, and the outside is dark red w/white streaks. My husband took a picture of it, while I was at the coast. Looks like a few will bloom this week, I will post the results as I get them. Nothing is blooming at the coast, I have them in the ground with mulch, it was 30 degrees for almost 5 days. The leaves took a hit, but it looks like they are coming back since the weather is back int he high 60's. Yesterday afternoon we spent the day at the beach, and it was just full of cars, from Minn, Ill, Iowa, Mich, and Canada. Barbra
