Kalanchoe. Asked about repeatedly on internet gardening forums. Congratulations on getting it to bloom.

Actually, the fruit of Passion Vine is highly edible -- you've just picked it too soon. Another common name for the vine is Wild Apricot, which should give you some idea of the general taste of the ripe fruit. When it's ripe the skin pales to a soft yellow green and the flesh will be quite soft. The ripe seeds inside will be dark. The black bug might be a leaf footed bug. They suck sap, but don't seem to do too much damage in my garden, unlike their relative the squash bug, which pretty much destroys my squash plantings every year.

PKponder, that ID looks right to me. Thank you. It seems to be a great plant. I flipped the picture 180 degrees on my phone now to see if it flips it right side up. Let's see...

It does look like calendula. Seeds, BTW, can spread far and wide by a number of different means, one of which is through animals &/or birds either ingesting and eliminating, or picking up and dropping. Sometimes seeds stick to an animal's body/fur/feathers and become dislodged later. Seeds can also be carried far and wide by water and wind. Even us humans can move seeds around if they stick to our shoes or clothing.
