I don't remember ever seeing a flower spike on a squash or pumpkin vine, Denise!
You may have had some hybrid seeds and this might be one of those odd parent types.
Another possibility is that it may have asters yellows. That disease effects far more plants than those in the aster family. I have seen some really weird common plants that have been infected. In fact, I have had squash with what I believe was asters yellows.
Now, someone can tell us about a squash or relative that produces a flower spike . . .
Well, I have been in California's Central Valley. But, apparently didn't pick up any of those seed things on my shoes! I'm sure I would have remembered!
Thanks a lot. I do believe it is Proboscidea lutea
Upon reading the recommended sites, I found that it is a close relative of sesame. It just so happens that I planted sesme seed in that location of the field last year. Maybe it is a cross or I got this seed instead of real sesame.
It is an intersting plant. I will do more research. Thanks for the help.
