Solidago altissima is a perennial wildflower with fine hairs on the stem and leaves located along the stem. It grows up to 6.7 feet (2 m) tall. One plant can produce up to 1500 small yellow flower heads in a large conical array. Unfortunately, this plant is self-incompatible, meaning that the pollen from one plant cannot pollinate the female flower parts of the same plant.
USDA hardiness zone 3a to 8b: from −40 °F (−40 °C) to 20 °F (−6.7 °C).
How to Grow and Care
Growing and planting Goldenrod is easy, as this plant will survive just about anywhere, though it does prefer to be grown in full sun. Goldenrod also tolerates various soil types as long as it's well-draining.
Goldenrod care is minimal once established in the landscape, with plants returning each year. They require little, if any watering, and are drought tolerant. Clumps need division every four to five years. Cuttings may also be taken in spring and planted in the garden.
Learning how to grow Goldenrod offers many advantages. Bad bugs can be drawn to the plant and consumed by beneficial insects that hatch their young there. Planting Goldenrod adds beauty and attracts butterflies to your landscape.
