Goldenrod (Solidago sp.) is one of the best wildflowers for late fall blooming & is very showy with large heads & flower clusters. Butterflies, hummingbirds, goldfinches, & other small birds are attracted to Solidago & feed on its nectar & flower seeds. Goldenrod is a vital fall-blooming plant that supplies nectar on the Monarch butterflies’ long migrations to their overwintering site in Mexico. Allow flower heads to remain in place overwinter to create a habitat for birds & small insects. Solidago (goldenrod) is at the top of Doug Tallamy’s list of essential plants for pollinators & other insects & considered a keystone plant. Solidago wildflower is best grown in full sun & well-drained garden soil. Sow Goldenrod seeds directly outdoors in a weed-free seedbed. Goldenrod seeds benefit from a late fall planting. The cold, moist weather of winter will actually help break the dormancy of the flower seeds. Broadcast the seed in late fall or early winter & lightly rake the Goldenrod seeds into the soil. When temperatures warm in the spring, the seed will begin to germinate. Height: 24 - 36 inches USDA Zones: 3 - 9 Goldenrod | Solidago Sp. Packet Of 25 Seeds With Free Shipping
