This is a perennial daisy-type yellow flower found on prairies. Individual flowers are about an inch to two inches across. In a prairie it is likely to be a spindly plant reaching about 5 feet high and with only a modest number of flowers. Put it in captivity and over-water as I did and you will get a much more impressive plant. It will be bushier with lots of stems coming up from the root. In several years mine got up to about 3 feet wide and 7 feet tall. It will bloom for several months from July to early September. Given how tall it grows you might want to place it in a spot where you can view it inside from an elevated location. Bubblebees and some small butterflys like it. All in all its a nice addition to a garden if you like tall plants.
Cold treatment is necessary to get the seeds started. In its first year expect it get maybe 3 feet tall and bloom in September. In later years you can dig up sprouts and put them in new locations, naturally keep them damp until they are well started.
