Dwarf Goldenrod

Solidago simplex

Solidago simplex is a perennial wildflower with one to several erect stems from 5-80 cm high. The herbage is glabrous throughout or somewhat sticky in the inflorescence. The basal leaves are oblanceolate to spatulate or obovate with toothed to mostly entire margins. The tips of the leaves are blunt or rounded and measure up to 15 cm long and 3 cm wide. The stem has a few leaves which become reduced upwards along the stem.

The inflorescence ranges from short and compact to elongated and narrow, the individual flower heads often subtended by long flower stems. The involucre is 4-6 mm high with shingled bracts with blunt tips. The 5-10 narrow rays are yellow and surround a narrow disk.
