|Too tall for a pumpkin!|
After a month or so in the ground, the plant's continued upright growth convinced me that it was not even third cousins once removed from the squash family. A plant-wise friend suggested yesterday that it is a Mexican Dahlia. My on-line search could find no foliage that is similar at all to this. Nor could I find anything that has the velvet leaf texture.
Things I get to do today include setting aside my pride and asking for your help. Feedback from all of you would be most appreciated.
