GENUS INDEX

GENUS CODE: SOLID
GENUS SCIENTIFIC: Solidago
GENUS AUTHORITY: L.
GENUS COMMON: Goldenrod
GENUS SUMMARY: A genus of 90-110 species, herbs, primarily North American, but with a few species in South America, Macaronesia, and Eurasia. The placement of the flat-topped goldenrods has been controversial; they are here included in Solidago rather than being treated as the separate genus Oligoneuron.
GENUS IDENTIFICATION: Identification notes: Several related genera readily mistaken for (and/or sometimes included in) Solidago are included here as keying “failsafes”.

NCBG DESCRIPTIVES

INTRO: Erect, rhizomatous perennial found in meadows, pastures, woodland borders and on road banks.
STEMS: Stems may be obscurely angled, unbranched, green to reddish and smooth or nearly so.
LEAVES: Leaves basal and alternate on the stem, sessile (upper) or winged-petiolate (basal) but not sheathing, oblong-lance-shaped to narrowly oval, to 8 in. long (basal larger), vaguely toothed or entire, often with hairs along margin.
INFLORESCENCE:
FLOWERS: Composite flowers (heads) in a terminal panicle, mostly on 1 side of the arching branches; heads about 1/4 in. wide, consisting of 7-13 yellow ray florets (often unevenly spaced and not open at the same time) encircling a central disk of 8-12 tiny, yellow, tubular florets. The narrowly bell-shaped base of each head (covered in tiny green bracts) is less than 1/4 in. long.

Plant Sale Text: Early Goldenrod can begin blooming in July. It is not too tall (to 4 ft) with delicate panicles of yellow flowers. It can handle full sun to part shade, dry to average well-drained soil. It is a clumping spreader, and can be divide if it fills in too much. Early Goldenrod attracts bees, butterflies and other pollinators. Songbirds eat it seeds.
