From the Ranunculaceae or buttercup family this European native is hardy to zone 3 but shouldn’t be planted south of zone 6.
It is about 2 feet tall but it will be taller in shade and forms nice mounded clumps from which the long stems arise. They sport 2 inch yellow flowers in May to July, but will often rebloom in fall if they like their spot. The flowers start out globe shaped (hence the name) and then open to a cup shape with cool bright yellow stamens popping out.
They defiantly like a rich moist soil but will do fine in a garden setting. They like cool weather rather than hot and dry and will do well in sun (morning is better) to part shade. Cut them back in mid summer when the foliage starts to spot and new fresh foliage will grow.
They are rabbit and dear tolerant so you can plant these if your hostas are getting eaten and they are nice with ferns and astilbe.$6.00
