Figuring out Goldenrod Flowers
Scientific Identify: Solidago spp.
Plant Household: Asteraceae, aster household
Different Frequent Names: Goldruthe, woundwort, Aaron’s rod, and solidago
Goldenrod is imbued with a determined botanical exceptionalism—heralding primarily from America, the place it has been employed for hundreds of years as an natural medication, dye plant, and beverage tea. Though most goldenrod species are native to North America, a number of species are native to Eurasia and South America. European goldenrod (Solidago virgaurea) is a vital folks treatment for lessening bleeding and diarrhea and therapeutic wounds—incomes it the title woundwort.1
Goldenrod’s Vary: Search for goldenrod in meadows, fields, and open woods and alongside trailsides and waysides. The vary varies by species—virtually anybody in North America has no less than a number of native species which can be considerable. A number of species of goldenrod have escaped cultivation in Europe and China. Solidago virgaurea is discovered throughout most of Europe, western Asia, and North Africa. It’s grown as a backyard flower and medicinal, which has probably expanded its vary over the previous few centuries.
Goldenrod Identification: Crush a goldenrod leaf when the plant is in bloom to familiarize your self with its distinctive aroma. I detect hints of resin and seaside within the perfume; an ideal mix of salt and balsam. In case you have a number of species rising in your area, get to know their nuances by tasting and smelling the leaves (after you’ve correctly recognized the plant to be goldenrod!). Some varieties are extra bitter, others extra astringent, and a few focus on resinous flavors. Candy goldenrod (S. odora) possesses honeyed hints of anise or licorice and is a prized beverage tea.
Any goldenrod species can be utilized medicinally, and identification to the species degree just isn’t important—that is welcome information, as they readily hybridize and are typically thought-about tough to establish by species. Nevertheless, be sure you have correctly recognized your species as a real goldenrod within the Solidago genus! Correct identification to genus is essential as there are yellow-flowered aster relations which can be lethal poisonous, together with ragwort and groundsel (these belong to the Senecio genus and its shut family members, that are described under within the look-alike part). It’s tough to specify the traits of such a big group of crops—a neighborhood subject information is indispensable for figuring out the species present in your space.
Leaves: Goldenrod crops have alternate, easy leaves that may be total or barely toothed, furry or easy. Leaves are usually longer nearer to the bottom of the crops, however they differ in form by species. The stems usually don’t department till they start to flower.
Flowers: Goldenrod’s flowering high (its inflorescence) is made up of a cluster of yellow flower heads. These flower heads appear to be a single flower to the untrained eye, however each is definitely comprised of as much as thirty particular person flowers, referred to as disc and ray florets. In case you look intently, this sample can simply be seen in a few of goldenrod’s family members, corresponding to sunflower and calendula. The flower heads are usually 0.4 inch (1 cm) or much less in width, though there are many exceptions—for instance, S. virgaurea. The inflorescence (flowering stalk) is most usually organized in a raceme or panicle, however is usually a corymb.
Goldenrod’s Look-Alikes and Associated Species: Goldenrod flower has numerous look-alikes, a few of that are lethal toxic. There’s a giant group of crops variably referred to as groundsel, life root, staggerweed, ragwort, and a slew of different regional names. These have been traditionally positioned within the Senecio genus, which is without doubt one of the largest genera of flowering crops, with over 1,200 species. The genus is in botanical flux, with many species being reclassified into new genera (over thirty new genera have been separated from the Senecio genus!). Clearly, we will’t go over all of the Senecio species—and their shut family members—however it’s good so that you can familiarize your self with the group and in addition to keep in mind that goldenrod does have some lethal look-alikes.
Not the entire Senecio members are poisonous, however the ones which can be toxic have dangerous pyrrolizidine alkaloids (PAs), compounds that may trigger irreparable injury to the livers of each people and livestock. PAs are notably insidious as a result of the signs of poisoning will be arduous to detect (they’re just like these of many different sicknesses) and may take months to manifest. Typically, by the point signs current themselves, the injury is already achieved.
I want there have been some simple option to differentiate goldenrod species from the Senecio genus, however I haven’t discovered any rule that holds true for the big selection of species. Usually, nonetheless, ragworts or groundsels have fewer flower heads than Solidago species. Senecio flower heads are usually bigger than the miniature Solidago flower heads (that are often smaller than 0.4 inch [1 cm] throughout), and Senecio species usually bloom earlier within the season than goldenrod. However there are many exceptions, so these variations should not arduous and quick. Once more, as a result of the groundsels are such a big group of crops, it’s prudent to get to know the genus (and its family members) and develop into accustomed to the species in your space earlier than you harvest goldenrod.
The Distinction Between Ragweed and Goldenrod: Goldenrod has been wrongly accused of inflicting hay fever merely due to its shut affiliation with the precise offender: ragweed (Ambrosia spp.). Each crops flower on the identical time, however ragweed has demure inexperienced flowers that are simply neglected—so, by default or responsible affiliation, goldenrod takes the warmth. Frequent ragweed (Ambrosia artemisiifolia) has lacy-looking leaves which can be divided and the plant branches freely. In distinction, goldenrod usually has an unbranched stem (till it flowers) and its leaves aren’t divided. (For the document, ragweed isn’t all unhealthy. Regardless of its propensity to induce a hissy slot in allergy victims’ nasal passages, ragweed is a local plant that performs an necessary ecological function—housing and feeding many bugs.)
In comparison with the wind-born pollen of ragweed (the higher to search out your nostrils, my expensive), crusing by the air with golden abandon, goldenrod is insect-pollinated and doesn’t launch its pollen into the air; due to this fact, that you must stick your nostril proper in its face to induce any type of histamine response.
Methods to Develop Goldenrod
Zones: Varies by species, so search for natives to your bioregion (there are lots of to select from in zones 3–9); full solar to half shade
Soil: Varies by species
Dimension: Varies by species, however typically 2 to five ft (0.6–1.5 m) tall; some goldenrods unfold aggressively by runners, and a few species modestly clump (increase in girth yearly)
Propagation: Stratify goldenrod seeds for 3 months earlier than planting and sow on the floor of the soil; don’t bury seed. Softwood cuttings, consisting of 4 to 6 nodes, taken in late spring, have a excessive proportion of profitable rooting. Divide the roots in spring or early summer time. Crops transplant effectively early within the season.
Siting and Backyard Care: Till just lately, North American gardeners scoffed at inviting this “weed” into the tended panorama. In the meantime, in Europe, goldenrod has obtained a heat welcome within the backyard and has been planted extensively for upward of three centuries. European breeders took goldenrod below their wings and emerged with showy cultivars match for the best of cottage gardens. Like several self-respecting opportunistic plant that thrives on disturbance, goldenrod jumped the confines of cultivation and promptly unfold into European fields and meadows. Gardeners in North America are actually recognizing that goldenrod’s commonness needn’t detract from its desirability as a decorative. Gardening supplies many nuggets of knowledge if we will merely handle to maintain the backyard gates of our minds well-oiled.
With a range of species to select from and native habitats starting from bathroom, to alpine meadow, to maritime dunes, you’ll be able to you should definitely discover one that can thrive in most any area of interest. Goldenrod flower is a mainstay in meadow gardens and is very pleasant when grown subsequent to its acquainted, purple-blooming sidekick ironweed (Vernonia spp.). (See the picture of the 2 chumming it up.) Different attainable native companions embrace frequent milkweed (Asclepias syriaca), cup plant (Silphium perfoliatum), and Joe Pye weed (Eutrochium purpureum and E. maculatum). For massing, think about planting fast-spreading species, corresponding to rough-stemmed goldenrod (S. rugosa), showy goldenrod (S. speciosa), tall goldenrod (S. altissima), and Canadian goldenrod (S. canadensis).2
In case your backyard house is proscribed, strive one of many extra demure clumping species, corresponding to candy goldenrod (S. odora) or any of the varieties described under. In a trial of goldenrod species performed by the Chicago Botanic Gardens, S. rugosa ‘Fireworks’ was a selection cultivar, with its resistance to powdery mildew, slowly spreading behavior, and explosive show of golden panicles. Different leaders embrace the hybrids ‘Child Solar’ and ‘Goldkind,’ each with tight-clumping habits and beneficiant floral shows. S. sphacelata ‘Golden Fleece’ is a late-flowering selection with heart-shaped leaves. Lastly, for the partial shade backyard, think about the variegated S. flexicaulis ‘Variegata,’ which is a modestly spreading species moderately than a clumping one.3
Goldenrod flowers within the late summer time to early fall, at a time when most gardens might actually use some perkiness. Spend only a few moments observing the pollinators flocking to the golden sprays, and you’ll admire how necessary a task it performs in sustaining native insect populations. Goldenrod helps over 100 species of caterpillars, making it a helpful plant for calling in native butterfly populations. It additionally attracts backyard beneficials, corresponding to praying mantises, ladybugs, murderer bugs, damsel bugs, syrphid flies, and parasitic wasps. The nectar is well-liked with many butterflies, together with monarchs.4,5,6
Downside Bugs and Illnesses: Goldenrod is commonly affected by powdery mildew and rust. See the selection cultivars listed above, which have demonstrated good resistance towards each illnesses.
Harvesting: Harvest crops with healthy-looking leaves—that haven’t been affected by powdery mildew or different illnesses—once they’re simply starting to flower. Harvesting in the beginning of flowering ensures that your dried blooms retain their yellow hue. In case you harvest the crops in full bloom, the flowers will mature into their fluffy seed heads as they dry, and also you’ll be left with boring puffs as a substitute of golden floral cheer! For goldenrod species which have a number of stems, I like to depart half the stems intact—for the pollinators and for the crops to proceed to photosynthesize. For species which have only one stem, I favor to chop the stem midway down, leaving some vegetation to photosynthesize for the rest of the season. You’ll need to make it possible for the species you’re harvesting is considerable, and you should definitely depart the vast majority of crops in a single space untouched. In case you’re harvesting non-native goldenrod, these identical cautions don’t essentially apply. Dangle the crops to dry, and strip the leaves and flowers from the stem when they’re crisp.
If powdery mildew is a giant downside in your space, think about harvesting goldenrod leaves earlier within the season earlier than the mold takes maintain. Simply be certain that of your identification, as you received’t have the attribute flowers current.
Goldenrod’s Culinary Makes use of and Preparation
Goldenrod’s resiny taste properly melds with each vinegar and honey. Meadowsweet and goldenrod make a beautiful pair in mead or as a naturally fermented do-it-yourself soda. See the recipes on the finish of this text.

Actions: Diuretic, anticatarrhal, anti-inflammatory, antimicrobial, astringent, carminative, vulnerary, and diaphoretic7
Energetics: Warming and drying
Medicinal Makes use of: A lot of what we learn about goldenrod’s medicinal makes use of comes from Native American peoples, who historically use varied goldenrod species for numerous illnesses, each topically and internally. Goldenrod is a vital dermatological help for sores, infections, toothache, burns, and wounds. Internally, it’s used for numerous urinary, respiratory, and digestive illnesses. The medicinal use by over a dozen Native teams for near twenty species of goldenrod has been documented, with overlapping utilization between species.8 It’s probably that much more species are used, contemplating the plant’s versatility and widespread distribution. Apparently, many tribes use the basis medicinally—a use not shared by most modern Western herbalists.
Though any species of goldenrod will be employed medicinally, aroma, style, and medicinal qualities differ between species. The overarching makes use of are related, however it’s as much as you to find their particular person nuances and develop a private relationship with the species you develop or forage. Some species are extra nice as a beverage tea, and a few are extra astringent. The latter group can be extra serviceable internally to gradual diarrhea and topically to disinfect, relieve burns, and gradual bleeding.
Goldenrod as a Sinus Treatment: Goldenrod is a premier decongestant, successfully assuaging higher respiratory congestion stemming from allergy symptoms, sinusitis, flu, or the frequent chilly. It may be taken as a tea, syrup, or tincture for this objective. In my expertise, it is without doubt one of the strongest herbs for drying the sinuses. To alleviate sinus ache and congestion, please see my Free and Clear Goldenrod Tincture Formula. Mix goldenrod with sage (Salvia officinalis) in a robust infusion for a gargle that can be utilized for sore throats, thrush, and laryngitis.7
Goldenrod as Urinary Tract Treatment: Goldenrod additionally has an affinity for the urinary tract and is used as a diuretic, antimicrobial, and anti inflammatory treatment for urinary tract infections. I like to mix goldenrod, marshmallow root (Althaea officinalis), corn silk (Zea mays), and uva-ursi (Arctostaphylos uva-ursi) in equal components to arrange a Urinary Tract Infection Tea, which is drunk at room temperature. The diuretic high quality of goldenrod can also assist to alleviate edema, gout, and kidney stones.7
Goldenrod as a Wound Treatment: Goldenrod is utilized by Native American peoples—and was adopted by European settlers—as a wash or poultice to assist heal wounds, burns, open sores, and cuts. The vulnerary makes use of of the plant impressed the scientific title Solidago, which suggests “to make entire.”9 John Parkinson wrote of European goldenrod (S. virgaurea) in 1640, “It’s the most soveraigne woundherbe of many, and may doe as a lot therein as any, each inwardly for wounds and hurts within the physique, and for both greene wounds, shortly to remedy them, or outdated sores and ulcers, which can be hardly to be cured.”1 Parkinson really helpful a decoction of the herb to assist “fasten the enamel which can be free within the gummes.” The Kawaiisu folks use a decoction of the leaves of S. californica on boils, open sores, and pores and skin irritations.8 Numerous species of goldenrod have been used as a wash for thrush and as a toothache treatment.
Goldenrod as a Digestive Treatment: Internally, many species of goldenrod have been used to quell diarrhea—probably due to their tannins and antimicrobial and anti inflammatory actions. Solidago species are usually bitter, warming, and pungent, which makes them helpful carminative herbs for exciting and bettering digestion.
Different Goldenrod Makes use of: Freshly picked goldenrod flowers lend a cheery splash of gold to bouquets, and the dried flowers are completely beautiful in wreaths and eternal bouquets. Decide the flowers earlier than they’re absolutely open to retain the golden hue. Once I was pregnant with my daughter, my hormones enchanted me: I grew to become obsessive about rising and arranging dried flowers. Dried goldenrod and candy Annie (Artemisia annua) have been my favourite fillers for wreaths. The blooms are used to dye silk and wool, lending a golden to olive-green colour, relying on the kind of mordant employed.
Sleek, tossing plume of glowing gold,
Waving lonely on the rocky ledge;
Leaning seaward, beautiful to behold,
Clinging to the excessive cliff ’s ragged edge.
