Help! ID for white flowered perennial

Hiya

Here's a white flowering perennial that perhaps some dear soul(s) can help identify. Its a perennial with fairly large leaves. White flowers and there's no pigmentation on the stems...until it sets seed in black circular clusters of berries. It gets to be about hip to waist high.

Thanks!

Phytolacca esculenta perhaps?

I would hope it isn't as invasive as the phytolacca americana that self seeds around my farm , so please beware there Batsy .
