Praise then darkness, and creation unfinished

There is a cucumber on one of my vines! I don't think it's ripe yet, and so will leave it at least another day, maybe several, but the first cucumber feels more like success than all the pretty bright-yellow flowers.

There are in fact a lot of flowers, and the vines have found the trellis. I think so far all the flowers are on two of the three plants; the third is growing, but more slowly.

Addendum (pulled out of comments): the third vine is also starting to flower. It looks like those may be male flowers, which would be useful if I'm right that most if not all of the flowers I'd seen so far are female.
