Euthamia graminifolia - Grass-leaved Goldenrod
Grass-leaved goldenrod "is an upright, erect, native
perennial with a many-branched inflorescence. It is an
herb of the Asteraceae family whose species name means
“grass-leaf”. It grows to 3–6 ft in height with a 1–2 ft
spread. The upper ½ of the plant appears bushy due to its
branched stems and grass-like, narrow to linear, alternate
leaves. It grows from a long-slender rhizome.
The stalk-less 2–4 in long leaves taper to a long point, and
narrow towards the stem. The leaf has 3–5 nerves
underneath and is minutely rough-pubescent along nerves
and margins. There are a few resinous dots on the
underside of the leaf. The lower leaves are deciduous
early in plant’s life cycle and the upper leaves are reduced
towards the inflorescence. The leaves omit a scent when
The primary stalk supporting the flower cluster is winged
and pubescent with hairs lying flat on the wing margins.
The flower heads are 2–2.5 in high, are arranged in dense,
stalk-less, small flat-topped clusters of 20–35 flowers
with s mall rays. It has pale to bright yellow flowers that
bloom in the late summer or early fall. The outer flowers
of the cluster open first. The flower heads are coneshaped and attached at the pointed end. The whorl of
small leaves beneath the flower is ovoid to bell-shaped.
The obtuse or rounded, yellow bracts around the flower
are somewhat sticky. These overlapping bracts are 3.1
mm long and occasionally have green tips. The .02 in (.5
mm) long seed is a hard, pubescent, one-seeded,
indehiscent white nutlet. The seed is attached to hair-like
bristles (pappus). The receptacle is finely fringed." (USDA)
