Cantelope seeds seem to grow the easiest. You might have had some in your compost. Enjoy....let us know the taste; it looks like it's going to be a real sweetie!
Oh yes, I'm pretty sure that is what happened. They came up close together, like maybe I accidentally dropped a seed clump into my compost collection pot. Initially, I wasn't sure but figured odds were for cantaloupe since I save the squash/pumpkin seeds to roast and watermelon, I would have noticed putting the seeds in the compost. Guess it worked out although the garden this year is impassible, thanks to the addition of these vines.
Can't beat a volunteer. I'm from the volunteer state by the way.
Perhaps the other one is watermelon , or squash , or egg plant of some kind ?
It's'definitely cantaloupe, the skin is right, the size is right but it has an evenly round, shape, unlike this first one that is deeply ribbed. I generally avoid putting any kind of seeds in my compost. That and the fact these all came up within a 2' radius leaves me confident they all came from the same melon but this would be second generation. Could easily been some natural hybridization going on.
Guess the test will be in the tasting. Think I will cut this one today.
