What is this? Weed or no?

[Varencienne]

Hello,
This plant has been growing quickly in my garden in a spot that I have typically had trouble with before (low light, lots of moisture). I tried planting a couple things there just before fall last year and now it is spring and this has come up. Not sure if this is a weed or something I want to keep. Looks pretty but looks can be deceiving.
I like in Calgary, Alberta, Canada if that helps.

Looks like catmint. Rub a leaf and see if it smells like mint.

It's definitely in the mint family. Around here I've noticed that bees love mints, even the wild "weed" variety, so I always see any mint as a plus in the garden.

I have this growing in a rock wall at my house I can't remember what it is. All I know is you can cut it back and it will come back even more Lush

It looks like one of the Deadnettle family?
