populations and morphological variations which has generally led to classifying it into two subspecies, which roughly speaking can be identified as being from the eastern and western parts of the continent. At least in the midwest, it is common to have plants of different ploidy interspersed, with little apparent tendency for one type to dominate even a fairly local geographical area.
Within Solidago, S. altissima is part of the Solidago canadensis
species complex, which is classified in the subsection Triplinervae. S. altissima has sometimes been classified as part of S. canadensis.

Description
S. altissima is one to two meters tall, with fine hairs on the stem. The leaves are located along the stem, not in a rosetteRosette (botany)
In botany, a rosette is a circular arrangement of leaves, with all the leaves at a single height.Though rosettes usually sit near the soil, their structure is an example of a modified stem.-Function:...

Classification
S. altissima has diploid, tetraploid, and hexaploidPloidy
Ploidy is the number of sets of chromosomes in a biological cell.Human sex cells have one complete set of chromosomes from the male or female parent. Sex cells, also called gametes, combine to produce somatic cells. Somatic cells, therefore, have twice as many chromosomes. The haploid number is...
