Lady’s Mantle (Alchemilla vulgaris)

Common names: Lady’s Mantle

Lady’s Mantle is a beautiful, hardy perennial herb cherished for its soft scalloped leaves, delicate chartreuse flowers, and long history of use in women’s herbal medicine. Known for its astringent and toning qualities, it is especially valued for supporting menstrual health, digestion, and wound healing.

White Ginger (Hedychium coronarium)
Family: Zingiberaceae

White Ginger, also known as Butterfly Ginger or Himalayan Ginger, is a striking perennial from the ginger family grown for its lush tropical foliage and highly fragrant white flowers. The blooms resemble delicate butterflies in flight and release a rich, sweet perfume often compared to gardenias, making it one of the most aromatic ornamental gingers.

Despite sometimes being mislabelled in trade (including in New Zealand), White Ginger is distinct from culinary galangal species. While its rhizomes are edible and carry a mild, ginger-like flavour, it is primarily grown as an ornamental and fragrant garden plant.

This vigorous plant produces large clumps of upright stems and spreads gradually via underground rhizomes, forming a bold, tropical presence in the garden. It thrives in moist to boggy soils and performs best in full sun to partial shade, especially where soil moisture is consistently high.

Your order includes one healthy plant, ready to establish and grow into a lush flowering clump. Growing instructions and care details are provided below.

Currently unavailable for 2026. Due to an unusually cool and marginal growing season, our turmeric crop produced very little rhizome division this year. As a result, we will not have plants available for sale in 2026.

Expected availability: July 2027. Please sign up below to join the waiting list and be notified when plants become available again.

Turmeric (Curcuma longa)
Family: Zingiberaceae

Turmeric is one of the world's most celebrated medicinal and culinary plants, prized for its vibrant golden rhizomes and long history of use in traditional herbal medicine. A close relative of ginger, it thrives in warm conditions and produces lush tropical foliage as well as highly valued underground rhizomes rich in curcuminoids—the compounds responsible for turmeric's distinctive colour and many of its researched health benefits.*

Widely used in curries, teas, tonics, and herbal preparations, turmeric has become a cornerstone of both traditional and modern wellness practices. Research continues to investigate its role in supporting healthy inflammatory responses, antioxidant activity, and overall wellbeing.

When available, each order includes one healthy turmeric crown, ready to establish and produce a new clump of rhizomes. Growing instructions, harvesting information, and culinary uses are provided below.

Woundwort (Stachys sylvatica)
Family: Lamiaceae

Woundwort is a hardy woodland perennial from the mint family with a long history of use as a traditional first-aid herb. For centuries it has been valued for supporting the healing of cuts, wounds, bruises, and skin irritations, earning its common name through generations of herbal use. In summer, it produces elegant spikes of deep purple flowers that are highly attractive to bees and other beneficial pollinators, while its lush green foliage makes an excellent addition to woodland gardens and food forests.

Evergreen Dwarf Comfrey (Symphytum grandiflorum)
Family: Boraginaceae
Common names: Dwarf Comfrey, Creeping Comfrey

Evergreen Dwarf Comfrey is a low-growing, spreading perennial valued for its lush evergreen foliage, early nectar-rich flowers, and exceptional usefulness as a living mulch and groundcover. Unlike Medicinal Comfrey, this smaller species is primarily grown for its ecological and soil-building benefits, helping to suppress weeds, protect soil, and feed beneficial insects. Hardy, resilient, and easy to grow, it is an excellent addition to food forests, orchards, and regenerative gardens.
Due to its smaller size and more compact growth than regular comfrey it is ideal for smaller gardens, urban environments and small food forests. It makes an excellent border plant and ground cover and does well planted around fruit trees.

Can be grown throughout New Zealand. Frost tolerant. 

Below you’ll find growing instructions, uses, and harvesting ideas.

Order is for 1 plant, bare rooted.

Russian Comfrey Crowns (Symphytum × uplandicum)

Russian comfrey is a highly valuable perennial for food forests, orchards, and organic garden systems. Known for its vigorous growth, deep root system, and ability to accumulate nutrients, it is widely used as a dynamic accumulator, compost ingredient, mulch plant, and natural garden fertiliser.

This hardy, low-maintenance plant produces abundant foliage that can be repeatedly harvested throughout the growing season and returned to the soil to support healthy plant growth. Once established, it forms a productive clump that returns year after year.

Each order includes 1 strong crown cutting with a growing tip. Plant directly into your garden over winter and it will emerge strongly in spring. Growing instructions and uses can be found below.

Horseradish (Armoracia rusticana)

Horseradish is a hardy, fast-growing perennial root crop valued for its powerful, pungent roots used in traditional culinary and herbal preparations. Once established, it produces vigorous leafy growth above ground and a deep, spreading root system below, forming a long-lived and highly productive plant.

Freshly harvested roots are grated or crushed to release their signature heat and aroma, traditionally used to make sauces, condiments, and medicinal preparations. A little goes a long way, making horseradish a rewarding and self-sustaining addition to the edible garden.

Each order includes 1 dormant, bare-root horseradish plant with a healthy growing tip (see example images below), ready to establish quickly and shoot strongly in spring.

Skirret (Sium sisarum)

Skirret is a traditional European perennial root vegetable that was widely grown from medieval times through to the 19th century, valued for its sweet, clustered roots. Often referred to in old texts as a “sugar root,” it produces slender, finger-like roots that are sweeter and more aromatic than carrots when cooked.
The flavour is gently sweet, nutty, and floral, with a soft, creamy texture when roasted, boiled, or pan-fried. At KoruKai Herb Farm, we especially enjoy it simply sautéed in butter, where its natural sweetness really shines.
Skirret forms a clump of multiple edible roots from a single crown, making it a productive and rewarding perennial vegetable for the home garden. Once established, plants improve in yield each year as the root system expands.

Your order includes a healthy seedling with developing storage roots and shoots (see sample image below). Plant it directly into the garden on arrival and it will establish quickly, re-emerging strongly in spring.

Growing instructions and care details are provided below.

Yacon, meaning “water root” in the Inca language, has been treasured for centuries in the Andes as a refreshing, thirst-quenching food for travellers. This vigorous perennial, related to the daisy family, produces crisp, juicy tubers with a uniquely sweet flavour—often described as a blend of fresh apple, watermelon, and pear.

Traditionally grown from Colombia to northern Argentina, Yacon is prized for its delicious edible roots, which can be eaten fresh or processed into the increasingly popular Yacon syrup. Its sweet juice can be concentrated into syrup, while the crunchy tubers make a refreshing and nutritious addition to the kitchen garden.

Yomogi (Artemisia princeps)
