The bright pink, Astilbe-like flowers of Queen of the Prairie bloom on tall stems in June and July. Filipendula ‘Venusta’ loves wet spots and will colonize a large area slowly.
'Siskiyou Pink' Wandflower has rose-pink delicate flowers that are suspended over the bronzy-green foliage, June through October. This may not be the longest-lived perennial, but the flower output makes it well worth planting. An introduction from Siskiyou Nursery in Washington State. Cut back when planting to rosette for winter survival. Needs good drainage to overwinter.
'Whirling Butterflies' Wandflower has delicate white flowers that hover over the green foliage all summer, from June to October. Cut back when planting to rosette for winter survival. Needs good drainage to over-winter, and prefers alkaline soils.
Spotted Cranesbill has deeply incised green leaves in a mounding habit. The flowers are produced in quantity from late April into June, in shades varying from pale pink to bright lavender-purple. As a native species of Geranium, it naturalizes well from seed in moist locations in both sun and shade. It is particularly effective as a loose woodland groundcover, especially when partnered with early spring bulbs, Ferns and Carex. This is one of Landscape Architect Larry Weaner's staples for his extensive work with natural meadows and woodlands.
PRN Preferred: A "must have" for a woodland garden, spreads moderately by seed.
'Espresso' Spotted Cranesbill has lavender-pink flowers over beautiful red-brown foliage that ages to bronze-green by late summer. A North Creek Nurseries introduction, found in Landenberg, PA.
'Max Frei' Bloody Cranesbill has pinkish purple flowers in May and June, followed by good reddish fall color. Semi-evergreen, and a good low-growing groundcover.
PRN Preferred: Dense foliage makes this a good low groundcover.
'Rozanne' ('Gerwat') Cranesbill has large blue-purple flowers with pale blue centers. It has a somewhat sprawling habit. This Geranium blooms all summer! A Blooms of Bressingham® selection found in England. 2008 Perennial Plant of the Year.

'Biokovo' Cambridge Geranium is a charming semi-evergreen groundcover which thrives in well drained sunny locations. The white blooms are tinged with pink at the base of the petals and are enhanced by red calyces. The flowers are produced in June and July, and hover gracefully over the low green foliage. The fall and winter color is also attractive, turning shades of bronze and red. Geranium 'Biokovo' was a natural hybrid found in the Biokovo Mountains of Croatia, so its cold tolerance is excellent. 2015 Perennial Plant of the Year.
Bowman's Root is covered with delicate floating masses of white flowers from May to July. The new foliage emerges in bronzy tones turning to green throughout the summer.

The name debate continues, with some voting for "Porteranthus trifoliatus".
