Ourisia prefers well-draining soil with good organic content. It can adapt to various soil types but performs best in loamy or sandy soils.
Ourisia requires moderate watering, especially during establishment. Once established, it becomes more drought-tolerant.
Ourisia grows best in full sun to partial shade, depending on the specific species and local climate conditions.
Ourisia is well-adapted to New Zealand's temperate climate and can tolerate both warm summers and cool winters.
The ecology of Ourisia involves its interactions with other species and its role in ecosystem processes. Understanding these relationships helps in conservation and cultivation.
Ourisia has various practical and ornamental uses. From traditional Māori applications to modern landscaping, this versatile plant serves multiple purposes.
Historically, Ourisia was used by Māori for medicinal purposes, food, and cultural practices. These traditional uses reflect the deep knowledge of native plants.
Ourisia generally requires minimal pruning. Remove dead or damaged growth as needed and shape the plant to maintain desired form. Pruning is best done in late winter or early spring before new growth begins.
Best planted in spring or autumn when soil is moist and temperatures are mild.
Collect ripe seed in late summer or autumn. Sow in a moist, well-draining seed-raising mix. Keep in a cool, shaded spot. Germination may take several weeks. Transplant seedlings when large enough to handle.
Divide established clumps in early spring. Ensure each division has roots and shoots. Replant immediately and water well.
Ourisia, known as native foxglove, is valued for its attractive flowers and is sometimes used in native gardens. While not prominent in Māori tradition, it is appreciated for its role in forest restoration and as a nectar source for native insects.
Alpine companions include mountain daisies, snow tussock, and alpine herbs. These plants thrive in exposed, high-altitude conditions.

Ourisia macrophylla (Native Foxglove) thrives in moist, humus-rich, well-drained soils with a slightly acidic to neutral pH. It prefers cool, sheltered sites with partial shade or dappled sunlight, mimicking its natural alpine and subalpine habitats. Consistent moisture is essential—water regularly during dry periods, especially in summer, but avoid waterlogged conditions, as the roots are prone to rot. Mulch around the base with leaf litter or compost to retain soil moisture and suppress weeds. This species is sensitive to drought and hot, exposed sites, so provide protection from harsh afternoon sun and drying winds. Ourisia macrophylla tolerates light frosts but may need winter mulch in colder regions. Fertilize lightly in spring with a balanced, slow-release fertilizer to encourage lush growth and abundant flowering. Divide clumps every few years in early spring to maintain vigor and prevent overcrowding. With attentive care, Native Foxglove will reward you with striking foliage and showy blooms, making it a standout in woodland, shade, or alpine gardens.
The cultural significance of Ourisia macrophylla extends beyond its practical uses. It represents a connection to the land and traditional knowledge systems that have been passed down through generations of Māori communities.
Today, the plant continues to be valued for its cultural heritage and is often included in restoration projects and educational programs that aim to preserve and share traditional knowledge about native plants.
