Slender goldentop, also known as coastal plain flat-topped goldenrod, is a North American native. It is not, however, a true goldenrod, though it is often classified as such. For a comparison table of goldenrods and similar species, see Solidago. Identification: Plants are 10-39" (25-100 cm) in height. Stems are branched partway up, smooth, without a waxy bluish coating (technically, glabrous or glabrate, not glaucous). Leaves are linear, like grass blades, abundant, and typically bent downward or backward (deflexed). They are ⅞-2½" (2.4-7 cm) long and ¹/₃₂-⅛" (1-3 mm) wide, rarely up to ⅛" (6 mm) wide and smooth, especially at maturity. Leaves have resinous dots. The flowerheads are flat-topped or rounded, often multiply layered, with tiny yellow flowers, blooming from Aug-Dec. Some Euthamias are listed below. This genus is in taxonomic flux, so the names are likely to change: |

Flowers | Flowerheads are flat-topped or rounded, often multiply layered, with tiny yellow flowers, blooming from Aug-Dec. | Large, flat-topped or umbrella-shaped yellow flower clusters. Each flower in the flowerhead is ⅛" (3.2 mm) across. Flowerheads tend to bloom gradually, not all at once, emitting a modest, sweet scent. | |||||||||||||||||||||||||||
Leaves | Linear, like grass blades, abundant, typically bent downward or backward (deflexed). ⅞-2½" (2.4-7 cm) long and ¹/₃₂-⅛" (1-3 mm) wide, (up to ⅛" (6 mm)) and smooth. Leaves have resinous dots. | Lance-shaped leaves contain 3 veins running along the length of the vein. Sometimes there is 1 or 5 veins, depending on leaf size. Leaves are 3-6" (7.6-15 cm) × ⅛-⅝" (3.2-15 mm), resembling grass blades, and attached directly to the stem (“sessile”). Leaves have resinous dots. | |||||||||||||||||||||||||||
Stem | Stems are branched partway up, smooth, without a waxy bluish coating (technically, glabrous or glabrate, not glaucous). | Stems typically have rows of fine white hairs. | |||||||||||||||||||||||||||
