General Culture:
Easily grown in average, medium to wet, well-drained soil in full sun to part shade. Best flowering in full sun, but appreciates light shade in drier soils and in hot, humid conditions.
Noteworthy Characteristics:
This mountain fleece cultivar is an upright perennial which forms large, dense, bushy, slowly spreading clumps, typically 3-4' tall. Features dense, bottle-brush-like, erect flower spikes (to 6" long) of tiny, crimson flowers over an extremely long bloom period of early summer to fall (sometimes to first frost) and large, ovate (cordate at the base), stem-clasping, dark green leaves. Unlike many of the other polygonums, this cultivar is not too aggressive but still needs lots of space. Sometimes listed or sold as Polygonum amplexicaule 'Fire Tail' or P.a. 'Speciosa'.
Problems:
No serious insect or disease problems.
Uses:
Provides long summer to fall bloom for the perennial border. Contrasts well with purple-flowered salvia, nepeta or perovskia. Also effective in moist areas along streams, water gardens or ponds.
