Extremely s-tier, amazingly easy to maintain. They spread by rhizomes so if you plant a few in an area and a couple of years the whole thing will be full of strikingly tall plants. They’re very resistant to all kinds of bullshit. They can be a really cool anchor plant for native garden sections adding a lot of height to boundaries or borders. They’re pretty showy and have lots of nice yellow flowers. Lots of insects like them. Some birds will eat the seeds when the season is over. Reseeds extremely easily. Could probably use for soil retention. Many different kinds so you can find something that fits your need. Lots of reasons to like this plant.
