I did some more googling and looking at pics on the web of goats weed and am sure this is what it is. In particular there is a thread on this forum that has an ad from Ebay for "Vietnamese black dragon" where it becomes clear that is also goats weed and the pic is identical to how my plants look in late spring:

So my five year search has ended and it has the homely name of goats weed. Goats weed. Apparently from Venezuela.
Well thanks a lot for all the replies on this thread.
