Mountain Fleece: Long-Blooming, Tall and Beautiful

Persicaria amplexicaulis

This tall perennial has been blooming for me most of the summer in a part-shade location with rich, moist soil. It used to be just 2 to 3 feet tall, but over time – say 15 or 20 years – it has gotten taller and more vigorous. This year it is 6 feet tall. It has bright red bottlebrush type flowers that are about 3 inches long and an inch wide. Each bottlebrush is actually made of many small flowers.

Mountain fleeceflower blooms all summer

Mountain fleeceflower grows best in moist soils in either sun or part shade. I have it growing in part shade under old apple trees, near where I have great success with primroses of all types. It spreads by rhizomes or roots that are fleshy and grow near the soil surface. I have not found it to invasive at all, but it spreads slowly. It is a native of the Himalayas.

One of the most endearing features of this plant is that it blooms for months on end. It started blooming by early July, and it shows no sign of fading away. It is a nice cut flower, too.

A related plant is giant fleeceflower (Persicaria polymorpha). This I grow in full sun in moist soil. It has big hollow stalks and forms a clump 6 feet wide and tall that gets bigger every year. The white flowers resemble astilbes on steroids. Mine bloomed in July, but the flower panicles still are interesting – though they are brown now.  Read more about it byclicking here.
