Pull one up. If it has long runner roots, it is likely milkweed- especially if it has a white sap. The leaves don't quite look right though, it resembles a weed that has yellow flowers. This particular weed tends to have a long taproot, and it WILL spread by seed. I think I've heard it called evening primrose, but I'm not sure if that is correct.
It could be milkweed like everyone is saying but the leaves look a bit different. If you don't like it, pull it out. Be careful cause it is an allergy attack waiting to happen.
it looks like primrose to me too, I had some until I ripped them out. First year they were about 18 inch, second year they got to 4-5 feet, yellow blossom spikes, curvy stems.
I thought it looked like Comfrey. Googled it and ...yep... all their photos look like this photo. Some gardeners grow it use as the "green" portion for making compost. (20% green to 80% brown-dry leaves, etc-) It grows fast, large and is a good way to grow stuff for making compost.
I am uploading a crude (very crude) drawing of the plant because the pictures don't really show the body of the plant. I have looked at pictures of all the plants you suggest and don't think it's any of them but I am not sure. I appreciate you helping me!!! Thanks.
Milkweed; PLEASE leave them! Monarch butterflies rely on them for food, and too many people eradicate the plant, and the butterflies' numbers a dwindling. It is NOT a pest. The 'milk' has been used for many years for skin ailments.
if u have one of those fancy phones, it will tell u what "it" is,.just by taking a pic and asking. for real, my husband does it all the time. He has the droid phone but the iphone does it too I believe.
I am sorry to report that the huge plants were probably weeds. They never bloomed and I took them out to put in flowers. I did plant a lot of milkweed for the monarch butterflies! Thanks everyone for your help!
Without milkweek the Monarch Butterfly will be gone forever.
