Ohio goldenrod (Solidago ohioensis) is a flowering, erect perennial that grows to about 3-4 feetin height. These goldenrod plants have flat, lance-like leaves with a blunt tip. They are primarily hairless and the leaves at the base of the plant have long stalks and are much bigger than the upper leaves. This wildflower bears yellow flower heads with 6-8 short, rays that open on stems that are branched at the top.

Once the flowers have blossomed, they turn from yellow to white as seeds develop. If you wish to save seeds, snip the heads before they become completely white and dry. Strip the seed from the stem and remove as much plant material as possible. Store the seeds in a cool, dry place.
Ohio goldenrod needs 4 weeks of stratification to germinate. Direct sow seed in the late fall, lightly pressing the seeds into the soil. If sowing in the spring, mix the seeds with moist sand and store in the refrigerator for 60 days prior to planting. Once sown, keep the soil moist until germination. As they are native plants, when grown in similar environments, Ohio goldenrod care only includes keeping the plants moist as they mature.

Many people think that this plant causes hayfever, but actually it just happens to bloom at the same time as ragweed (the real allergen), from late summer into fall.
Makes a great cut flower.
Store seeds in a cool, dry place.
