Organically grown at KoruKai Herb Farm, Banks Peninsula, New Zealand, without the use of synthetic fertilisers, pesticides, or herbicides.
Goldenrod is a beautiful, long-lived perennial that deserves a place in every herb garden, cottage garden, wildflower meadow, or food forest. From mid to late summer it produces masses of brilliant golden-yellow flower spikes that sway above the foliage, creating a spectacular display while attracting bees, butterflies, hoverflies, and many other beneficial insects. It is one of the best late-season nectar plants for pollinators and adds valuable colour to the garden when many other flowers have finished.
Growing to around 60–70 cm tall, European goldenrod is easy to grow, highly adaptable, and returns reliably year after year.
Medicinal Uses*
Goldenrod has been valued in European herbal medicine for centuries and was traditionally known as Woundwort because of its historical use for supporting the healing of cuts and wounds. Today it is best known as a herb for supporting the urinary system. It has traditionally been used to promote healthy kidney and bladder function, support the body's response to urinary tract discomfort, and help flush excess fluid from the body through its gentle diuretic action. The herb is approved by the German Commission E for supporting urinary tract health and has traditionally been used alongside increased fluid intake as part of urinary wellness protocols.
Goldenrod is also rich in flavonoids, including quercetin, which contributes to its traditional use for supporting the body's natural inflammatory response and helping relieve seasonal allergy symptoms such as hay fever. It has also been used traditionally to help clear excess mucus from the respiratory tract and to support the body's natural defences against fungal overgrowth.
Growing Conditions
Goldenrod is an extremely hardy perennial that thrives in a wide range of conditions. It grows best in full sun but will also tolerate light shade. Well-drained soil is ideal, although it performs remarkably well in clay, sandy, and even rocky soils. Avoid overly rich or heavily fertilised soils, as these can encourage lush, floppy growth.
This is an excellent plant for New Zealand gardens, tolerating both hot, dry summers and frosty winters with ease. The foliage dies back completely each autumn before re-emerging vigorously from the crown in spring.
Established plants gradually increase in size and can be divided every few years during winter to rejuvenate the clump and produce new plants. We recommend allowing newly planted crowns at least one full growing season before dividing them.
Planting Instructions
Goldenrod is supplied during its winter dormancy as a bare-root crown with healthy growing buds already formed. Plant as soon as possible after receiving your order.
Choose a sunny position and prepare the soil by incorporating compost before planting. Dig a hole slightly larger than the root system and position the crown so the growing buds sit just above soil level. Firm the soil gently around the roots, water thoroughly, and apply a generous layer of mulch around the plant while keeping the buds free of mulch to prevent rot. Mark the planting position and, if birds are a problem in your garden, protect the area with bird netting or a few branches until new shoots emerge. Depending on your climate and soil temperature, growth usually begins between September and November.
If planting several crowns, space them 40–50 cm apart to allow room for mature clumps to develop.
Harvesting
Goldenrod is best harvested when it is in full flower, usually from mid to late summer. At KoruKai Herb Farm we harvest in the early part of the day, once the dew has dried but before the midday heat, to preserve the quality of the herb. Using secateurs or a sharp knife, cut the flowering stems about 10 cm above ground level. The plants generally regrow well and, under favourable conditions, may provide a second harvest later in the season.
Processing and Drying
Lay the harvested stems in a single layer on drying trays with good airflow and dry out of direct sunlight at 37–40°C. In good drying conditions the herb is usually ready within one to three days. Once fully dry, strip the leaves and flowers from the stems and store them in paper bags or airtight glass jars in a cool, dry place. Ensure the material is completely dry and crisp before storing to maintain quality.
Herbal Preparation*
The flowering tops and leaves are traditionally prepared as herbal teas, tinctures, and liquid extracts. Goldenrod has long been used to support urinary tract and kidney health, encourage healthy fluid balance, assist with seasonal allergies, and promote the body's natural healing processes. It has also traditionally been used as a mouthwash or wash for minor skin conditions.
