Solidago rigida -- (Stiff Goldenrod)


A favorite nectar source for Monarch butterflies, this widely adaptable golden beauty excels in any well-drained soil. It will grow beautifully in even the most inhospitable clay and dry, sandy and rocky soils.  The brilliant yellow flowers appear in August and September.  The three to five foot tall stems make excellent perches for birds.  The seeds are an important late season food for songbirds, and the dried heads are lovely in dried arrangements.  Prefers full sun, but will also thrive with at least a half day of direct light.
