Euthamia graminifolia (L.) Nutt.
Flat-top Goldentop, Grass-leaved Goldenrod
Asteraceae (Aster Family)
USDA Symbol: EUGR5
The 1-4 ft., branched stems, bearing long, narrow, grass-like leaves, are topped by flat, open clusters of small, yellow flowers. Flat-top goldentop spreads by rhizomes to form colonies.
The flat-topped floral arrangement and narrow leaves of this Goldenrod are distinctive. Slender Fragrant Goldenrod (E. caroliniana) has grass-like leaves with tiny resin dots and only one rib or vein.
