Originally posted by TinaS Mine aren't actually Black-eyed Susans. The flower looks the same, but the rest of the plant is different. They are considered a weed, but I like them.
I just looked back at the post of yours that seems to be the one that was being referred to. The flowers look like one of the species of annual sunflower. The centers of Black-eyed Susans are smaller, compared to the length of the yellow "petals,"
How tall do they get? Two to four feet? They could be grown plants from the black oil sunflower seeds from your own or from a neighbor's birdfeeder. They at most get to about five feet tall, and have much smaller blooms than the mammoth Russian sunflowers that grow as tall as 12 feet.
If you don't cut them down, and leave them standing as the flower heads dry, they are going to attack goldfinches! A nice follow-up to the bees!
