@NilaJones Interesting. I have some growing in the front but it is much drier there and doesn't do so well. The one in the veggie garden is healthy but not aggressive.

This has a lot of uses, especially medicinal. https://www.herbcottage.com.au/blogs/grow-your-health/yarrow Note the contraindications tho.

Oh, I put the occasional leaf in a garden salad, chopped well. I don't notice the bitterness so much.
