An extremely invasive Eurasian weed. Kill it (if you can) before
it multiplies. Incidentally, it's quite edible, if you like
garlicky and mustardy flavours. (Alliarum officinalis)

I'd go with Dames' Violet except the flowers are much too small
(do they themselves grow bigger?)

Other than that nothing much seems to match the leaves in the
4-petal section of Newcomb.

If you're thinking of Dame's Rocket, Hesperis matronalis, the plant
is too small, and it's a bit early for it, too. While you sometimes
see white ones, they are usually shades of purple.

The cactus thing is all over and I'm too impatient to wait for a
flower (might be a hundred years!). What is it?

It's common mullein, Verbascum sp. It's biennial. Later this summer
the rosette will put up a flower stalk 1.5-2m tall, with yellow flowers,
unless it's one of the cultivated ones which have white or purple
flowers (unlikely). Mullein is another common Eurasian weed.
