since i was wrong with first guess i didnt say my second guess, which is gaillardia. DH was mowing yesterday and nicked the tops off so they are mangled and hard to compare. hopefully mine will bounce back and later in the spring we will get a better idea what you have. My gaillardia is unknown seeds self collected on vacation 2014 in florida, it had a lovely pinkish bloom like the new punchbowl variety. if thats what you have its gorgeous and under 24".
