 This species does not spread by suckers like most others 

 of the section Spiraria. All the last named species are 

 valuable as late-blooming shrubs and decorative with 

 their showy panicles of bright or deep pink fls. They 

 appear at their best when planted in masses in the 

 wilder parts of the park in low ground.
