Well, you have left me with quite the puzzle! Here is the packet of seeds I bought:
http://www.lakevalleyseed.com/Squash_Cucuzzi_p/625.htm
The front of the packet is exactly the same as this picture. However, online the “Botanic Name” is Cucurbita pepo. The botanic name on the back of my package is “cucurbita maxima”. The description online and packet is the same: “This unusual Italian heirloom is in a class by itself. At maturity, it grows into a long hard-shelled gourd on a long trailing vine. Normally harvested when 8-12” long, it is used like regular summer squash. Enjoy baked, grilled, raw, frozen and pickled.”
The picture on the front does not look like either cucurbita maxima or pepo, at least not what I could Bing. It does look like the Lagenaria siceraria.
So what do I have? The Botanic Name on the online packet doesn’t match the one on my actual seed packet. The picture doesn’t match either the online botanic name (cucurbita pepo) or the botanic name on my package (cucurbita maxima).
If the darn thing would germinate and grow, I’d eventually find out!
