As summer turns into fall, the leaves start to change from bright reds, purples, lavenders, and pinks to deeper colors like yellows, golds, oranges, deep reds, and browns.
I learned to eat and make herbal remedies based on the season because the changes in nature mirror the rhythms of our own lives. One easy way to eat seasonally is to include colorful foods like squash, pumpkin, fall apples, and tomatoes. The bright yellow flowers of goldenrod (Solidago spp.) are also easy to find when making seasonal herbal remedies. ) as well as several other fall herbs.
Goldenrod is a brightly colored wildflower that blooms in late summer and fall. With its vibrant yellow flowers, goldenrod brings a pop of color along roadsides and in fields during autumn. But this plant has uses beyond just its ornamental beauty. Goldenrod has a long history of use as an herbal remedy, and many herbalists harvest this plant to make teas, tinctures, salves, and more.
In this article, we will explore tips and best practices for sustainably harvesting goldenrod. We will cover identification, timing your harvest, which plant parts to use, preserving and drying methods, and how to ethically forage this abundant fall wildflower
Overview of Goldenrod
There are over 100 species of goldenrod, but the most commonly used medicinally are Canada goldenrod (Solidago canadensis) and blue-stemmed goldenrod (Solidago caesia). These herbaceous perennials can grow from 2 to 7 feet tall depending on conditions. They produce branched clusters of bright golden yellow flowers atop thin, elongated stems. The leaves are lance-shaped with toothed edges.
Goldenrod grows in a variety of habitats from fields and meadows to roadsides thickets, and open woods. It thrives in disturbed soils and spreads readily via underground rhizomes. Goldenrod ranges across most of North America except for the far northern areas.
This plant has a long history of use among Native American tribes, early American settlers, and traditional herbalists. The entire plant can be used both internally and externally. Goldenrod is valued for its anti-inflammatory, antiseptic, diuretic, and astringent properties. Modern research has also uncovered valuable antimicrobial and antioxidant effects.
Identifying Goldenrod
-
Goldenrod has clusters of small bright yellow flowers at the top of tall, thin stems. The flowers have a faint sweet scent.
-
Leaves are lance-shaped, toothed, and arranged alternately along the stems. They have parallel veins and can sometimes appear wrinkled.
-
Plants grow from 2 to 7 feet tall depending on conditions. They have upright, wand-like stems that branch near the top where the flowers occur.
-
Habitat includes roadsides, abandoned fields, meadows, thickets, open woods, disturbed soils, and drainage ditches. Spreads readily via rhizomes.
-
Blooms late summer into fall. Provides a splash of golden yellow during autumn.
-
No poisonous look-alikes, but can be confused with other yellow-flowered plants. Positively identify before harvesting.
When to Harvest Goldenrod
Timing your harvest carefully is important to get goldenrod at its peak potency and flavor. Here are some tips on when to harvest different parts of this plant:
Leaves – Harvest leaves before flowers appear in early-mid summer. Choose healthy, vibrant leaves and avoid any that appear damaged, wilted, or infected with powdery mildew.
Flowers – Harvest goldenrod flowers when they are in full bloom, which occurs in late summer into fall. Pick flower clusters when the tiny individual flowers are open and bright yellow.
Stems – Cut stems along with flowers during flowering season. Select long, straight, healthy stems.
Roots – Dig roots after foliage has died back in late fall or early winter once the ground has frozen.
Seeds – Collect seed heads once flowers have faded and gone to seed in mid-late fall.
Ideally harvest goldenrod in the morning after any dew has evaporated but before the heat of mid-day. Find locations away from roadsides or areas treated with herbicides.
How to Harvest Goldenrod
Follow these steps for responsibly harvesting goldenrod:
- Seek permission if harvesting on private land. Only harvest where you have permission.
- Positively identify the plant (see notes above). New foragers should go with an expert.
- Scan the area for healthy, robust plants away from roadsides or polluted areas.
- Use scissors or pruning shears to selectively harvest branches with an abundance of leaves or flowers. Don’t harvest more than 20% of any one plant.
- For roots, use a digging fork or shovel. Dig carefully to get the roots and rhizomes. Replace any disturbed soil.
- Place plant material in paper or cloth bags. Avoid plastic. Keep out of direct sun.
- Label bags with plant name and harvest location details. Record harvest date.
- Clean materials well at home, removing dirt, debris, and any damaged portions.
Sustainable harvesting is key when wildcrafting goldenrod. Never harvest endangered populations, and only take what you need from healthy, abundant plants. Taking too much can threaten the survival of local populations.
Preserving and Drying Goldenrod
Proper drying is crucial for preserving goldenrod’s medicinal properties. Here are some tips:
-
Leaves – Dry leaves on screens or loosely packed in paper bags in a warm, well-ventilated area out of direct sun. Leaves are fully dry when crumbly.
-
Flowers – Hang flower clusters or lay singly on screens to air dry. Keep out of direct sun to preserve color. Well-dried flowers retain vibrant yellow color.
-
Roots – Slice roots and dry on screens or in a dehydrator until brittle. Roots are very hard, so drying thoroughly is important.
-
Seeds – Dry seed heads on screens until seeds shake loose for storing.
-
Monitor closely to prevent mold. Discard any moldy portions. Store fully dry material in glass jars out of sunlight.
You can also freeze fresh goldenrod leaves or flowers in ice cube trays with a bit of water for use in teas and foods. Tincturing fresh plants in vodka or glycerin is another good preservation method.
How to Use Harvested Goldenrod
Once dried, goldenrod can be used to make:
-
Teas – Infuse dried leaves and flowers for anti-inflammatory and diuretic teas. Add honey for flavor.
-
Tinctures – Macerate fresh flowers in vodka for several weeks then strain to make a medicinal extract.
-
Salves – Infuse dried flowers in oil then add beeswax to make a topical healing salve.
-
Syrups – Make an herbal syrup using fresh or dried flowers for coughs and colds.
-
Spices and flavors – Use fresh or dried flowers in foods like soups, baked goods, syrups, and infused honey or vinegar.
When sustainably harvest and dried properly, the bright golden blossoms of this wildflower can be transformed into valuable herbal remedies that provide wellness benefits as well as a touch of botanical inspiration during the autumn months.
Key Tips for Harvesting Goldenrod
-
Positively identify goldenrod species before harvesting. New foragers should learn from an expert.
-
Harvest goldenrod when the plant part needed is at its peak – flowers in full bloom, leaves before flowering, roots after foliage dies back.
-
Use ethical harvesting practices – don’t overharvest, only take what you need from robust populations, and avoid endangered or fragile habitats.
-
Dry thoroughly on screens or in paper bags out of sunlight to retain color and potency.
-
Store in airtight glass jars away from direct light. Use dried goldenrod for teas, tinctures, salves, culinary uses, and more.
With its bright yellow blooms and abundance along roadsides, goldenrod is a great plant for beginning foragers to start with. Follow sustainable harvesting practices to craft your own herbal remedies from this wildflower treasure.
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. But in our area, they are usually only 3 to 4 feet tall. The plants can grow up to 7 feet tall. 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 flower heads are bright yellow and mostly grow on one side of a long branch that hangs 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 want you to find the type that works best for you and your needs, preferably one that is easy to get where you live. 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 aren’t sure if you have found the right plant, leave it! To get better at foraging and herbalist activities, it is best to go with an experienced forager or herbalist first. Also, it’s helpful to read your plant identification books very carefully before you start, and to use more than one book to be sure you have the right name for a plant. Generally, once you know how to identify a specific plant, that knowledges becomes solidly ingrained in your head.
Timing Is Everything
Any herb that you want to get the most out of needs to be harvested by paying close attention to the stages it goes through. Goldenrod is no different.
Goldenrod Leaves
When I go goldenrod foraging, I like to get the leaves just before the flowers open, or when some flowers are open and others are about to open. Goldenrod is prone to powdery mildew and rust, so choose your leaves with care to avoid infected leaves. In fact, when foraging goldenrod, it’s best to keep an eye on the plant’s overall health and only pick from strong, healthy plants.
Goldenrod Flowers
If you dry goldenrod flowers when they are fully bloomed, they often turn into fluff, so I like to use them right away.
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. When it’s hot, I like to put the things I’ve found outside in brown paper bags (mark them so I don’t forget what they are) and store them in the backseat of my car. Then, I’ll park in the sun with the windows open so air can circulate. But if you want to do this in the fall, you need to be careful to pick the best day. This is best in the summer.
