My sister and her husband and my cousin and his wife were on vacation last spring. I don't know where they were, but they each bought a commercial pack of dipper gourds. They both have many gourds growing and are happy with what is growing. They don't have pure dipper gourds. They went up over the fence and now they are over the roof of my sister's potting shed and into the apricot tree. They may have to get the fire company's ladder truck to harvest the gourd crop.
I also traded for banana gourds and received the multi-colored fall gourds.
