Nursery contributed plant descriptions

Rugged little perennial with rigid, upright stems, 15” tall, topped by pretty spikes of small pink florets May to June, frequently repeating again in fall. Holds its own with rooty shrubs; interplant with iris, geranium, upright campanulas. Sun to part shade, best with some water but also takes boggy sites. Deer resistant. May spread some in moist sites but easy to manage.
Vigorous and hardy in zones 3-7, this late spring/early summer bloomer commands attention with its 30" stems bearing cylindrical clusters of soft pink flowers above low mounds of green ovate foliage. 'Superba' does like a moisture retentive soil, and it isn't happy in areas with long hot humid summers.
Bees like these pink bottlebrush spike flowers with a lavender tinge that bloom June and July. The large leaves become rich red in fall. 2.5 - 3' T and clumping to 2' W. Minimum temperature: -40?F
Clump forming semi-evergreen with broad mid-green foliage and wonderful dense spherical spikes of soft pink flowers well above their leaves. Flowers over a long period from summer into autumn. Easy to grow, and to cherish.
The showiest of all the knotweeds huge heads of pink flowers atop 75cm stems, on a moist rich site these are fantastic.
