What is the consensus about the hanging gardens of babylon?

by KuroOni

For all the wonders of ancient time, i believe their remains have been found, or some evidence of it. But for the hanging gardens of babylon, i believe no evidence has ever been found, and people have theorized that something of that scale that requires constant maintenance is impossible to achieve at the time.

So what is the general consensus on the matter?

Bonus question, but if king nebucha... Whatever his name is built them according to the legend/evidence why are they offen attributed to Semiramis. Why are they even called hanging gardens of babylon if they were not built in babylon?
