September 2019 – Native Plant of the Month

Goldenrod/Solidago spp., Solidago canadensis/Tall Goldenrod
Late summer in Texas is a tough time for a plant to begin to flower, and the many perennial species of Solidago that grow across the state are some of the most dependable plants for wildlife to find blooms on at this time, despite any heat and drought. Growing everywhere from wetlands and prairies to drylands and cliff faces, Goldenrods are a very adaptable and diverse genus of plants that have much to offer humans and wildlife. The different species also have a variety of growth habits, from small clumping species, to some that will spread quickly through their roots, and go as far as they can reach.
Their bright yellow hues are a welcome sight for pollinators at the end of a tough summer. Goldenrods can be counted on to tough out the worst and still show their best colors. Solidago blooms are often super loaded with a great variety of pollinator species buzzing around them, since they provide a vital surge of rich pollinator forage at a time when many insects and other plants may be trying to recover from a harsh summer before winter.
Goldenrod’s flowers and leaves have also long been recognized as having useful medicinal qualities, and remain popular as a hardy wild remedy plant in many pollinator gardens.
The drought endurance, ability to grow in poor conditions, and rapid-spreading habit of some species may also make them too vigorous for companion planting in vegetable and herb gardens. However, these same qualities make those species ideal for re-vegetating ecologically-degraded areas with beneficial plants for wildlife, and are a great choice for areas with poor soils and low species density. Even in gardens, they can be carefully introduced (especially in more depleted soils that need organic matter) and used to suppress other plants like Bermuda grass, or to provide just enough shade for herbs and veggies in late summer, when not allowed to smother them.
These hardy but aggressive species of Goldenrod are great as support plants, and excel in wildflower borders, hedges, and tall grass prairie settings. They do best when they are allowed to grow in dense colonies, or with other tallgrass prairie plants for structural support.
