Mountain Daisy
Celmisia lateralis
Full sun with airflow; gritty, lean mix; keep the crown dry in winter with a gravel mulch. See our alpine plants guide.
Description
Clumping alpine daisy with narrow leaves and white flower heads on fine stems. Suited to exposed, stony positions and alpine troughs.
Key Identification
Fine, linear foliage and white daisies on slender stalks; thrives in lean, fast‑draining media with maximum light.

Habitat
Natural Distribution
occurs in natural habitats characteristic of Aotearoa, forming part of distinctive plant communities where site stress and local disturbance shape vegetation patterns. It favours exposed slopes, screes or fellfields with thin, rapidly drained mineral soils, enduring intense radiation, wind and freeze-thaw cycles. On the coast it occupies sunny, wind‑prone sites with sandy or rocky substrates, where salt‑laden air and periodic drought limit competition. These preferences explain its patchy distribution and sensitivity to changes in hydrology, competition and disturbance regimes. Celmisia lateralis
Conservation Status
Current Threats and Protection
are influenced by land use, browsing and weeds. Protecting intact habitat mosaics, reducing browser pressure, and managing invasive plants sustain recruitment. Where local stands are small or isolated, eco‑sourced augmentation and careful site stewardship help secure long‑term viability. Celmisia lateralis Populations of
How to Grow
Cultivation Requirements
Provide free‑draining soils and high light appropriate to the species’ natural range. Use gritty, stony mixes and an open aspect with moving air; keep crowns high and dry, especially in winter. Choose warm, sunny sites with shelter from the fiercest onshore winds; avoid heavy, waterlogged soils.
Planting Guide
Best Planting Practices
Plant in the cool, moist months into weed‑free ground. Set plants slightly proud of the surrounding soil, water to settle, and mulch with coarse gravel or woodchips while keeping the stem base clear. Grouping two to three plants replicates natural patterns and improves establishment under local conditions.
Ecological Role
Environmental Benefits
contributes structure and seasonal resources where it grows, providing cover and habitat for invertebrates and, when flowering or fruiting, nectar, pollen or seed for fauna. By tolerating the stresses of its environment, it helps stabilise sites and enrich small‑scale habitat diversity. Celmisia lateralis
Uses
Traditional and Modern Applications
Ideal for rock and gravel gardens that emulate alpine processes, or for specialised collections. Suited to sunny, maritime gardens with sandy or rocky soils where wind and salt are considerations.
Landscaping Uses
Garden Design Applications
Excellent for rock gardens, alpine collections, and naturalistic plantings. Best used in open, well-drained positions where its distinctive form can be appreciated. Combines well with other native alpine plants and provides year-round structure. Consider placement carefully due to sharp foliage - avoid high-traffic areas. Creates dramatic focal points in contemporary and native-themed garden designs.
Seasonal Care
Year-Round Maintenance
Spring management focuses on removing winter-damaged foliage and assessing drainage. Summer care emphasizes maintaining adequate moisture without waterlogging. Autumn preparation includes reducing irrigation and ensuring good air circulation. Winter protection may require covering in areas subject to excessive moisture. Year-round monitoring ensures early detection of problems and maintenance of optimal growing conditions.
Pruning
Pruning Techniques
Little pruning is required; remove dead or crossing material after flowering and avoid hard renovation cuts. Light tip‑pruning maintains compact form without compromising the plant’s natural character.
How to Grow Mountain Daisy
From Seed
Propagation from fresh seed is the primary method for Celmisia lateralis . Collect seed as soon as it is ripe in late summer or autumn.
Sow seeds on the surface of a sterile, gritty seed raising mix. Maintain moisture without waterlogging. Placing the seed tray in a cold frame over winter can provide natural stratification, improving germination in the spring.
Seedlings are small and should be grown on in pots for at least a year before planting out.
From Cuttings
Celmisia lateralis can also be propagated from cuttings, which is best done in early summer or late spring. Select healthy, non-flowering shoots.
Trim the cuttings to about 5-7cm long, removing the lower leaves. Dip the cut end in a rooting hormone suitable for semi-ripe wood. Insert the cuttings into a propagating mix of sharp sand and perlite.
Keep the cuttings in a humid environment but ensure good airflow to prevent rot. Rooting can take several months. Once rooted, pot up individually.
Cultivation Notes
This species requires a sunny, open position with sharp drainage. It is well-suited to alpine troughs or rock gardens where its compact habit can be appreciated.
Soil should be gritty and low in nutrients. Avoid rich composts which promote soft, disease-prone growth. Mulch around the plant with stone chips to keep the collar dry and cool. It is fully hardy to frost but dislikes winter wet.
Pests and Diseases
Common Problems and Solutions
Good siting prevents most problems-sharp drainage and appropriate exposure are key. Crown and root rots arise if winter wet persists; keep crowns elevated and water moving. Protect young plants from browsing where deer, goats or rabbits are present.
Cultural Significance
Traditional Uses and Values
As a member of the widespread Celmisia genus, known as 'Tikumu' by Māori, this species shares in the cultural importance attributed to New Zealand's mountain daisies. While not among the large-leaved forms specifically used for traditional kapes (rain cloaks), its presence in alpine landscapes contributes to the enduring natural heritage of Aotearoa. It symbolizes the resilience and adaptability of native flora to harsh mountain environments, and its delicate flowers add to the seasonal beauty of the high country.
Bonus Tip
Expert Growing Advice
For a truly thriving Celmisia lateralis, focus on sharp drainage and good airflow, especially in lowland gardens where humidity can be an issue. Mimic its natural alpine habitat by planting in scree beds or raised rockeries, ensuring its crown stays dry to prevent rot, allowing this stunning plant to flourish.
