Solidago bicolor, with several common names including white goldenrod, silverrod and (in Québec) verge d’or bicolore, is a plant species native to much of eastern North America.Linnaeus, C. Systema Naturae, ed. 12 2: 556. 1767.Flora of North America, Solidago bicolor 1767, White goldenrod , silverrod , verge d’or bicolore It is found in Canada (from Manitoba to Nova Scotia) and in the United States (every state completely east of the Mississippi except Florida).Biota of North America Program 2014 county distribution map It prefers sandy and rocky soils, and can frequently be found along roadsides. Solidago bicolor Solidago bicolor is distinctive in the genus. Stems are thin and wiry. Flowers are white rather than yellow, the heads mostly clustered in the axils of the leaves rather than displayed in a large terminal raceme.

06Genome at a glanceCCDB
The complete instruction manualSolidago bicolor carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.

Where the DNA of Solidago bicolor was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
