Solidago
( sol - id - DAY - goh )
At-A-Glance InformationCommonly called Goldenrod, this genus of perennial flowering plants needs full sun to light shade and moderate water. Their flowers will attract birds and butterflies to your yard. They are native to the Eastern regions of the United States, and bloom from the middle of summer through fall. They are so commonly encountered in their native range that the Goldenrod is the official state flower of Kentucky. Flowers form in branched clusters and are yellow; leaves are green. They are easy-care plants and thrive in semi-poor soils. Goldenrod is perfect for informal border plantings or for naturalizing in meadow landscapes.

They are typically found growing along roadsides or in other areas with disturbed soils. Flowering stems are thin and wiry, and flowers are white, unlike most species in the genus. The flower heads are found in leaf axils. |
Solidago canadensis (Canada Goldenrod, Canadian Goldenrod) These herbaceous perennial plants often form colonies of upright shrubby plants with green foliage and yellow flowers that bloom towards stem tips. They are native to northeastern and north-central North America, and are considered invasive in Europe and Asia. This species is commonly grown as a garden ornamental in native, pollinator, and cottage or informal gardens. |
Solidago virgaurea (European Goldenrod, Woundwort) These plants are widespread across Europe and North Africa as well as Asia. It is grown as a garden ornamental and has many subspecies and cultivars. In the fifteenth and sixteenth centuries, they were used to heal wounds due to its astringent and antiseptic properties. |
Solidago gigantea (Tall Goldenrod, Giant Goldenrod) This species is the state flower of Nebraska, and forms clumps of upright stems with green foliage. Flowers are yellow, and bloom in drooping arrays of many flower heads (up to several hundred). Plants in this species grow in a wide variety of habitats, as long as soil is at least seasonally moist. |
Solidago Hybrid Varietals
These cultivars have been bred to do well in garden settings, and are typically a bit smaller and bushy than the species in the genus. These are great choices for garden ornamentals, and will attract pollinators to the landscape.
