Weed or flower
Is this plant a weed or flower.? This is it's second year in the garden. I pulled it last year as I did not see any flowers. It is 3 to 3.5 feet tall. Needle like leaves are bunched in 3s on tall stalks. It has spread like mad. Thank you.
There is so much going on in these photos, it's hard to see individual plants, but we think we know which one you mean. Looks like lespedeza. There are several species, but it's a good chance, if it is a volunteer, that this is one of the non-native ones that has become invasive, e.g. Chinese lespedeza. Do not let it go to seed. Chinese lespedeza should be destroyed.
You are welcome to send us a photo of it in flower, but, again, do not let it go to seed.
