Worthwhile native plant or invasive weed? #639944

Asked May 23, 2020, 3:52 PM EDT

Can you identify these? They may have been planted by the previous tenant or they may be weeds that blew in. The honey bees LOVE them in the summer but the fluffy seeds that develop and blow around are a mess. I am trying to decide if they should stay or go. They are growing in really poor soil, so they have that going for them. Any suggestions?

Hi and thanks for contacting Ask an Expert.

That is fireweed. It is considered a weed by some and a pollinating plant for bees and other pollinators by others. You are right bees love it. The flower heads can be removed when you see them wilting and therefore, you will not have the mess when they go to seed.

Chamaenerion angustifolium, known in North America as fireweed, in some parts of Canada as great willowherb, and traditionally known as Saint Anthony's Laurel. It is a perennial herbaceous flowering plant. It is native throughout the temperate Northern Hemisphere, including large parts of the boreal forests.The pluses are it grows well in poor soil, pollinators love it - cons are seed heads make a mess and it reseeds readily.

It is called fireweed because it often is found growing in burned forests. Definitely a native and referred to as a native wildflower. Controlling it would mean deadheading the flowers after they bloom.

I have added a link with some pictures for your review: https://oregonstate.edu/dept/nursery-weeds/weedspeciespage/fw/fireweed2_page.html

There other pages that note its use as a medicinal for inflammatory conditions.

If you have further questions, please contact us again.  My suggestion:  keep some of it for the bees, deadhead regularly.
