Upland White Goldenrod (Solidago ptarmicoides)

from $5.50
Sold Out

Upland White Goldenrod was thought to be an aster in times past! But, it was found to hybridize with goldenrods (specifically, Houghton’s goldenrod and Ohio goldenrod—other flat topped goldenrods), so it was reclassified to the Solidago genus (or Oligoneuron as some still classify it) .

This dainty plant grows from one to two feet tall. The leaves are long and thin. There are 3-60 flowers in a flat-topped formation, with white rays and a creamy center. Truly lovely! It blooms from July to September and ranges throughout Michigan but it isn’t common in southern Michigan.  It is a plant of fens, alvars, sandy prairies and Lake Superior rocky shores.

I have seen this plant in full sun, but Minnesota Wildflowers indicates that it can also grow in part shade, so maybe on the edge of a woodland garden. 

As “upland” is in its name, it does fine in drier soils. 

There is special interest for this plant since the leaves turn rainbow colors in the fall!
