The mystery vine that came up where we planted our green beans and took over the entire bed has been producing cantaloupes like crazy. There are about 40 fruits on there that are bigger than a baseball. Cantaloupes slip from the vine on their own when they are ripe and we have had four slip so far. Several different looking melons have grown on the same vine so I’m guessing that the seed was from a hybrid melon probably from the grocery store.
I have no idea how it got there, but I would assume in our compost? We have eaten two of the melons and they are great texture, but not very flavorful. The larger ones with the stripes down them are much less flavorful than the smaller ones. It was fun and interesting to let them grow, but not as much fun eating them.
Have you had any mystery plants show up in your garden?
