I have two large philadendrums (I know that's not spelled correctly, and I can't find it in the dictionary). they are on either side of my front porch and have been there for 10 years at least.
The younger of the two has grown something that looks like a banana. The day after we first saw it, it opened up to reveal a white cone shaped thing inside. It was open that one day only. I have checked it in the morning, around noon, and in the evening. It closed back up and has not reopened that I have seen.
Do these things bloom? The older plant was well established when we bought the house over 12 years ago. I planted the younger one about 11 years ago. Any information is greatly appreciated.
