I went to a customer's house today to work and I noticed this in her carport. I blurted out "What IS that beautiful thing? It looks like a pumpkin!" She proceeds to tell me that this was a pumpkin and it dried this way. She said that she bought two and one turned to pumpkin soup and this one just continued to dry. I asked her if she did anything to get it this way and she said no, it just happened, and she had never seen anything like it before.
Truth be told, neither have I but I have strong inclinations to think that this is a very large gourd that is perfectly shaped like a pumpkin. It's incredibly light for its size (about 18 inches tall) and you can hear the seeds rattle inside but still, the size of the stem along with the roundness and indentations make it look just like a ghostly pumpkin.
Anybody out there might know what species of gourd this might be?
