Anyone know which native Japanese plants/flowers were introduced to Canada?

@django I'm guessing the unruly Japanese knotweed would be one...!

@django oh hm apparently Matricaria discoidea (pineappleweed). (am reading the Wikipedia list of plants native to Japan)

@django Are you looking for stuff that's specific to Japan, or do widespread East Asia natives count?

Autumn olive (Eleagnus umbellata) is China/Japan again.

My partner is doing a mural and wants to pay hommage to an elderly Japanese neighbor who was a florist. So anything that is common in Japan but has taken root in Canada.

@django Oh how lovely! You'll probably want things that aren't considered noxious weeds then... You might look at traditional Japanese flower symbolism too -

Of the flowers on that page, I know the Japanese camellia is frequently brought over as an ornamental, though AFAIK it hasn't naturalized. And can only be grown in fairly limited regions of Canada.

@django Oh, wasabi maybe? Again, not escaped to the wild AFAIK, but definitely grown as a crop in BC.

Ah, I would not have thought of that one πŸ˜‚

Wow, this is amazing, and specific flowers meaning would possibly trump the symbolism of 'rooted' in Canada!

I just don’t know where to look for this type of info!


Kudzu was introduced to the US from Japan (though it's native range includes much more than just Japan) and has now been found in Canada, most likely from the US (and therefore of Japanese origins).
