Korean Chrysanthemum
by Ann McCulloh - posted 09/27/13


The pink and gold flowers of Dendranthema zawadskii ‘Hillside Sheffield Pink’ open over a period of four to six weeks.

The warm, soft tints of Korean chrysanthemum (Dendranthema zawadsii) flowers create a color counterpoint to fall foliage in the October garden. Korean chrysanthemums are later-booming and have a softer form than typical garden mums. The foliage of Korean mums forms an attractive mounding shape all season long, even before the plant covers itself in daisy-like autumn blooms. The plants also tend to be pest and disease resistant and long lived. Such a reliably hardy, late-blooming perennial should be much better known. Its relative obscurity may be due to the fact that it blooms at a time of year when most gardeners are not actively shopping for plants, and so overlook it.
