got any other pics, it can be a fig tree, a melon, a squash, or an empress tree. how old is it?

Not a watermelon, looks kindof like a bush squash.

I agree, not a watermelon. Looks like a melon of some sort or a gourd.

Some kind of Cucurbit, squash or pumpkin.

You might be stuck with that smallish pot--those vine-vegetable types of plants do not like transplanting.

Besides the size of the pot, the plant needs to develop both male and female flowers at the same time and may need hand-pollination unless there are bees about. Then it will be so late in the season the plant will need to be in a warm room with lots of light.

Thanks for all the replies! It may well be some kind of gourd I planted. There was a neat one I found at the farmer's market (it tasted like cucumber to me when I ate some raw). I planted some of those seeds in one pot.

I actually did transplant the entire smaller pot into a larger pot. But it's still a fairly small pot. We will see if it moves into the larger pot with its roots. Nice to look at at least.

I took a few more photos.

I don't know when this plant started sprouting, but the big-leaf growth has been within the last two weeks, in Western NY (so, late July).

Maybe I will be able to share more info as it grows bigger.

And here is one more of the flowers that are growing:

Hmm, the images are small here. Here is the full size one:

Here is a link that might be useful: {{gwi:122155}}

a Cucurbit for sure

Thanks. This might have been something like the gourd I'm thinking of:

This page is nice, but I haven't read it fully, if anyone is interested in cucurbits:
