east of the Blue Mountains of Oregon, not in subalpine 
situations. 
It is a hardy perennial, with tuberous roots like those of 
the common Peony, but much smaller; it grows little more 
than a foot high, and flowers about the middle of May. It 
may be increased like the other Ponies, either by seeds or 
by division of the roots. 
It seems rather difficult to keep, for the old roots sent 
home by Douglas, as well as all the young ones raised from 
seeds and given away by the Horticultural Society, have 
died, the only plant now alive being that in the Society's 
Garden, where it grows vigorously, planted in a mixture of 
silver sand, peat, and a small portion of loam, more than 
one-half of the whole mixture being sand. It is kept in a 
north aspect, where the sun only shines on the plant a few 
hours during the middle of the day in summer, and not at all 
in winter, and where the temperature is not subject to very 
great variation during summer. The plants which perished 
died chiefly during the hotter part of summer and autumn, 
when fully exposed to the sun. It seems necessary that they 
should be covered in winter with a hand glass to keep the 
roots rather dry.
