Wrinkled Goldenrod Solidago rugosa
Other Common Name(s):
- Phonetic Spelling
- so-li-DAY-go roo-GO-suh
- Description
-
A compact, cascading, clump-forming native with 2-5 foot stems that have radiating light yellow flowers at the tips. Flowers in September. Numerous tiny, toothed leaves have rough, wrinkled surface. A great addition for late season color and to lure the butterflies in. Also attractive to birds, native and honey bees. It is found in moist sites as sandy swamps, wet sandy prairies, sandy banks of marshes, acid gravelly seeps, sand dunes, and rocky bluffs.
In recent times goldenrods have been blamed for hay fever, but its irritating symptoms are actually caused by ragweed (Ambrosia species), whose pollen is airborne when the goldenrod is in flower.
Rough-Leaf Goldenrod is a herbaceous perennial that grows to 4 feet. Stems are hairy and upright with rough-textured leaves at the base. Arching spikes of yellow flowers appear in late summer and early fall. It needs full sun to light shade and moist to wet soils.
Fire Risk: This plant has a medium flammability rating.
