Queen-of-the-Prairie lives up to it's name with it's tall stature and big, airy clusters of pink flowers. Unfortunately it doesn't flower every year here and when it does it flowers late, in late August - September. It needs to be planted in a sunny place to increase the chances of it flowering as much as possible. Like other Filipendula species it prefers moist soil, rich in lime, although it can grow very well without it. It can supposedly spread with rhizomes, so it might be a good idea to plant it in a wide pot.
