weed

Looks like you have red rooted pigweed, also known as common amaranth. Get rid of this weed before the bristly parts drop lots of seeds into your garden bed. Some people do eat parts of this plant....but I doubt you purposely planted it.

It is pigweed.

Extremely healthy pigweed :)

Elisa your post made me smile. Thank you nature girl. We pulled it and nice and pretty bright red roots. Not sure where it came from. We have it no where else in the yard but did add a new bag of garden soil this year.

Pigweed can be introduced by manure, and the bristly seed heads can also hitch a ride on your shoes from elsewhere. It is an amaranth, and the young leaves are edible; at one point I allowed a few plants to grow in my garden each year (along with lamb's quarter) for early cooked greens. In the 3rd photo, the plant midway down the left side (before the seed head appears) is at a good harvest stage. There are foragers here who walk the edges of farm fields, harvesting the wild amaranth in large quantities.

Pigweed is not as hard to deal with as some weeds, but if allowed to go to seed, it will produce thousands, so it should be removed before the seed head appears. If the bristles are already present, dispose of them outside the garden.
