Goldenrod is a tough, fall flowering plant that can brighten up your garden. It doesn't spread aggressively and its floral display comes in the autumn when other plants have passed their prime. Ohio Goldenrod is great for flower borders as it blooms while many flowers are about to die or wilt away during winter months - one of few deciduous perennials with golden yellow colorings! Its pollen causes hay fever allergies but not necessarily because ragweed releases more pollen than golden rod does; rather, this weed's inconspicuity confuses people into thinking they have an allergy caused by oak tree leaves instead of getting diagnosed properly before too much time has gone by without relief from symptoms - Ragweed may be present throughout summer until early October
