As we move into fall, the colors of the landscape begin to change from the brilliant reds, purples, lavenders, and pinks of summer to the deeper colors of autumn—yellows, golds, oranges, deep reds, and browns.
As these seasonal changes in nature relate to our own rhythms, I was taught to eat and make herbal preparations according to the season. Incorporating colorful foods like squash, pumpkin, fall apples, and tomatoes is an easy way to eat seasonally, and when it comes to making seasonal herbal preparations, one doesn’t have to look far to see the bright yellow flowers of goldenrod (Solidago spp.) as well as several other fall herbs.
Goldenrod is a common wildflower that grows abundantly across North America While some people consider it a nuisance weed, goldenrod has a long history of medicinal and practical uses Learning how to properly identify, harvest, and utilize this versatile plant can be a great way to connect with nature and make the most of free, natural resources.
Identifying Goldenrod
There are over 30 species of goldenrod native to North America. They can be found growing in open fields, along roadsides, and in disturbed areas. Goldenrod blooms in late summer and early fall, producing bright golden-yellow flowers that form tall plume-like clusters at the tops of the stems.
Some key identification features of goldenrod include
- Woody, ribbed stems that can grow 3-7 feet tall
- Alternate, lance-shaped leaves that get smaller toward the top
- Rough, hairy texture on the underside of leaves
- Bright yellow flowers clustered into plumes or panicles
Goldenrod species can be difficult to differentiate, even for experts. For medicinal and craft uses, specific species identification is not critical since all goldenrods have similar properties and uses. Just avoid plants like ragwort that can look similar but are toxic.
When to Harvest
The best time to harvest goldenrod is when the plants are in full bloom, typically August through September. Gathering the flowers right as they reach peak bloom ensures the maximum concentration of beneficial compounds.
Only harvest goldenrod growing in clean areas, away from roadsides or potential sources of contamination. Also avoid picking from plants that show signs of disease or damage.
How to Harvest
For fresh use:
- Use gardening shears or scissors to snip off entire flower plumes. Try to get as little stem as possible.
- Handle flowers gently to avoid bruising.
- Use flowers immediately or store in the refrigerator for up to a few days.
For drying:
- Cut flowers when blooms are partially open and still vibrant.
- Gently wash and pat dry flowers.
- Lay flowers face-down on a screen or baking sheet.
- Place in a warm, well-ventilated area out of direct sunlight.
- Allow 1-2 weeks for thorough drying.
- To test for dryness, flowers should crumble easily.
- Store dried flowers in an airtight container in a cool, dark place.
For tinctures/oils:
- Harvest fresh goldenrod flowers.
- Fill a jar with tightly packed flowers.
- Pour alcohol, oil, or vinegar over the plant material until completely submerged.
- Infuse for 4-6 weeks, shaking periodically.
- Strain and store the infused oil in a cool, dark area for up to a year.
No matter what part of the plant you use, always leave some behind to ensure future regrowth. Never harvest an entire stand of goldenrod.
Medicinal Uses
Goldenrod has a long history of medicinal use among Native American tribes. Current herbalists recommend it most for treating urinary tract, respiratory, and digestive complaints. Scientific research has also identified anti-inflammatory, antimicrobial, and analgesic effects from the plant.
Some of the most common medicinal uses for goldenrod include:
- Urinary tract infections – relieves symptoms and inhibits bacterial growth
- Kidney stones – helps relax ureters to aid passage of small stones
- Respiratory infections – reduces inflammation and has antimicrobial effects
- Upset stomach/indigestion – settles digestion and reduces gas
- Sore throat/mouth – has soothing, anti-inflammatory effects
Goldenrod can be utilized in several forms:
Tea – Add 1-2 tsp dried flowers to 1 cup hot water. Steep for 10 minutes and strain. Drink up to 3 times daily.
Tincture – A concentrated liquid extract made by soaking fresh goldenrod flowers in alcohol for 4-6 weeks. Take 30-60 drops in water or juice up to 3 times per day.
Infused oil – Soak flowers in a carrier oil for 4-6 weeks, then strain. Apply topically to soothe sore muscles, arthritis pain, or skin irritation.
Salve – Add infused oil to beeswax to create a balm. Apply to skin abrasions, burns, or insect bites.
Always consult an herbalist or medical professional before using goldenrod medicinally, especially if pregnant, nursing, or taking prescription medications. Start with small doses and increase cautiously if desired effects are not seen.
Craft Uses
Beyond its medicinal value, goldenrod has some excellent applications for DIY crafts and decor. The bright yellow flowers and sturdy stems create beautiful arrangements and natural dyes. Some fun ways to use harvested goldenrod include:
-
Flower arranging – Fresh or dried goldenrod adds a pop of color and texture. Pair with other fall blooms.
-
Wreaths/garlands – Entwine fresh goldenrod stems and flowers intocircular wreaths or swags to decorate for autumn.
-
Floral displays – Bundle dried goldenrod and display in vases or jars for long-lasting indoor decoration.
-
Dyeing – Goldenrod produces a pale yellow dye. Use like any natural dye with alum mordant on wool, silk, or other natural fibers.
-

-
Bath/body products – Add goldenrod-infused oil or hydrosol (distilled flower water) to soaps, lotions, bath salts, etc.
With its vibrant color and wildflower beauty, goldenrod is one of the harbingers of autumn. Learning how to properly identify and harvest it sustainably allows you to benefit from its many uses. Turn your backyard “weed” into a versatile addition to your herbal medicine cabinet and craft supplies.
Timing Is Everything
Harvesting any herb requires your full attention to the stages it goes through in order to harvest the plant for optimal benefits, and goldenrod is no exception.
Goldenrod Leaves
When I’m foraging goldenrod, I prefer to harvest the leaves just before the flowers open or when some are open and others are just opening. Goldenrod is prone to powdery mildew and rust, so choose your leaves with care to avoid infected leaves. In fact, it is best to keep an eye on the overall condition of the plant when foraging goldenrod, harvesting from healthy, robust plants.
Goldenrod Flowers
Be aware that drying goldenrod flowers (when in full bloom) often leads to the flowers turning to fluff so I like to use the flowers fresh.
Goldenrod Seeds
Some people will wait until the goldenrod goes to seed before foraging and drying the seeds.
Goldenrod Roots
Harvest the roots in the fall after the first heavy frost. Wash them well, cut them up into small, thin pieces, and dehydrate them thoroughly.
Time of Day for Foraging Goldenrod
I typically forage after the dew has dried and before the sun is at its hottest. That is around 11:00 AM this time of year where I live.
I try to get my harvest processed immediately. If drying, I put them in the food dehydrator. Air drying in the fall can be tricky due to dampness and lack of warm temperatures. If the temperature is high, I like to place my foraged material in brown paper bags (mark them so you don’t forget what they are) and put them in the backseat of my car. Then, I’ll park in the sun with the windows open so air can circulate. This is ideal in the summer, but if you want to do this during the fall months, you have to be careful to pick the best day for it.
3 Tips For Foraging Goldenrod
First, make sure you have one of the Solidago plants! S. canadensis can be found growing in dry or semi-wet areas. The plants can get up to seven feet tall, but are usually around 3 to 4 feet in our area. Flowers appear in mid to late summer and can continue through September—sometimes even October. The leaves are 2 to 5 inches long, are lanceolate, and have fine hairs on them. Some of the leaves smell like anise, but many do not. The brightly colored flowers are yellow and mostly grow on one side of a long branch that droops over.
Most people agree that S. canadensis and/or S. odora are the tastiest and most beneficial for health, but everyone has their favorite. I encourage you to find the variety that works best for you and your purposes, preferably one that is easily obtainable in your location. Many herbalists feel that most goldenrods are easily interchangeable.
Correctly identifying a plant is critical to foraging success. Many plants have poisonous look-alikes, and the Solidagos are no exception. The Senecio species in the daisy family can look similar to goldenrod to a new herbalist or forager. If you are unsure whether or not you have found the correct plant, leave it! It is best to go foraging with an experienced forager/herbalist before attempting to do it yourself in order to gain experience. It’s also a good idea to read your plant identification books very carefully before starting out and to cross-check between multiple books to positively identify a plant. Generally, once you know how to identify a specific plant, that knowledges becomes solidly ingrained in your head.
