Mallow Ninebark grows among pine and fir on rocky hillsides and slopes.

This is a tough draught tolerant medium sized shrub that resembles a currant.

Mallow Ninebark frequents eastern portions of British Columbia, Washington and Oregon and also parts of Idaho, Montana, Wyoming, Utah and Colorado. It is cold hardy and will endure hot dry conditions, USDA zones 4-8.

It is a deciduous shrub with lobed leaves that turn brilliant red in the fall.

The flowers are white with 5 petals and yellow centers and appear in early summer followed by brown seed husks in the fall.

As the shrubs mature, the gray bark becomes very stringy and peels.

This shrub is a great choice for tough climates.
