That's bad luck James, there's often a lot of wind when they flower I find. One of mine has a kink but they stood up to it well this year. You might as well cut off the part above the break now.
If it has yellow flowers it might be one of the other mustard type of plant. It isn't coltsfoot which flowers before the leaves and is only just putting up the leaves.
But it still looks like Alliaria petiolata to me.
Yep, I think so
Not very much sun would be fine though it would do OK on the north side.
If you want to google it, call it Lamprocapnos spectabilis. The name changers have been around that family.
Very hardy, I don't grow mine in full sun, they're very fleshy and I don't think they'd be happy.
I couldn't get it big enough to count legs Bob
It looks mite shaped though
A possibility not a definite ID
Bombylius major maybe, aka bee fly or bee mimic. Lots about at the moment.
It's grown in flowing water commercially but that might be to avoid it smelling of stagnant water. It does fine in my pond with no flow.
