Slightly shorter than their close cousins, Prairie Dock, these are still very large herbaceous plants. Their common name comes from a tendency for their leaves to be oriented on a north-south axis along the upright blooming stems. Given their stature and the fact that they are known to live upwards of 100 years, carefully consideration is recommended when selecting a location for one of these.
Please check out the Prairie Moon listing at the link above for more details.
