Is this a weed?

A friend sent me this photo of a plant in her daughter's new Ontario garden.
"She and her husband moved into their new house late last fall and are finding all kinds of nice plants coming up in their garden (including marijuana!) However this one has us stumped. It could be a weed, but we are not sure."

Do you know what it might be?

 

Rumex of some kind, common name dock.

 

Thank you. I knew it looked familiar. Perhaps it is a species that has culinary uses but I think most Rumex are considered weeds aren't they?

I have Rumex flexuosus in my garden but I grow it more for its novelty than beauty. Pacific Northwest Gardening:Favored Weird Plants you can't wait to burst from the ground

 

Armoracia rusticana

 

Thanks.

 

Now they're obligated to have roast beef.

 

Well, yes, that's another perspective. I guess the determination of whether or not horseradish is a weed depends on whether or not the homeowners are vegetarians. It isn't that pretty to be a garden ornamental alone.

 

Sundrop is correct, - of course Armoracia rusticana.

 

Of course. Was anyone questioning Sundrop's ID?

 

No, I just confirm that my initial identification was incorrect.

 

I apologize.
