Mustard Plant

This is Tower Mustard. I found it at my grandmother's house, i used the Seek app to find out what it was.

It's an endangered plant in the UK, but not in the USA.

It's scientific name is Arabis glabra.

What's weird is that it can NOT be used to make mustard! it's going to have small creamy colored flowers, so stay tuned.
