Yellow Snow Marguerite

Botanical name: Dolichoglottis lyallii
Synonyms: Senecio lyallii, Senecio lyallii var. lyallii
Common name(s): Yellow Snow Marguerite, Lyall’s Daisy

About:
Yellow Snow Marguerite is a striking alpine perennial endemic to New Zealand, producing large golden-yellow daisy flowers above bold clumps of leathery foliage. Adapted to harsh mountain conditions, it is one of the most spectacular flowering herbs of the South Island high country and provides a brilliant display during the alpine summer.

Natural habitat:
Occurs naturally in alpine and subalpine herbfields, moist rocky slopes, stable scree, tussock grasslands, stream margins and sheltered depressions in mountain environments.

Growing environment:
Prefers full sun to light shade in cool climates with excellent drainage. It grows best in gritty, stony soils rich in organic matter and benefits from consistent moisture without becoming waterlogged. It is highly frost and snow tolerant but dislikes prolonged heat and humidity.

Endemic distribution:
Endemic to New Zealand. Found naturally throughout alpine regions of the South Island and Stewart Island/Rakiura.

Height:
30–60 cm when in flower

Width:
30–50 cm

Flowering:
December–February (summer)

Fruiting:
January–March

Uses:
• Alpine and rock gardens
• Native alpine collections
• Scree gardens
• Botanical gardens
• Conservation plantings
• Pollinator-friendly gardens

Appearance:
Growth habit:
A robust, rhizomatous perennial herb forming dense clumps or colonies from underground rhizomes.

Leaves:
Large, leathery, dark green leaves form a substantial basal rosette. They are oblong to elliptic with wavy or coarsely toothed margins and may exceed 20 cm in length. The foliage remains attractive throughout the growing season.

Flowers:
Large, brilliant yellow daisy-like flower heads are carried on sturdy upright stems well above the foliage. Each flower consists of numerous bright yellow ray florets surrounding a yellow central disc, giving the entire flower head a rich golden appearance.

Fruit:
Small dry cypselae topped with a fine white pappus that enables the seeds to be carried by the wind.

Ecology:
Yellow Snow Marguerite is an important component of New Zealand’s alpine herbfields, providing nectar and pollen for native alpine insects during the short mountain growing season. Its lightweight, pappus-bearing seeds are dispersed by wind, allowing the species to colonise suitable alpine habitats.

Associated habitats:
Alpine herbfields, subalpine grasslands, stable scree slopes, rocky terraces, mountain stream margins, fellfields and snowbank communities.

How to grow:
Grow in a cool, sunny position with sharply drained soil rich in coarse grit or fine gravel. Keep the soil evenly moist during the growing season but never waterlogged. It performs best in cooler southern climates and alpine gardens where summer temperatures remain moderate.

Propagation:
Propagation is difficult and is generally undertaken only by specialist alpine growers or botanical institutions. Fresh seed should be sown as soon as it ripens, and established clumps may occasionally be divided with care. Wild plants should never be collected or disturbed.

Cultural use:
Named in honour of the Scottish naturalist and Royal Navy surgeon David Lyall (1817–1895), who explored Antarctica, New Zealand, the Arctic and North America. Although there are no widely recorded traditional Māori uses, the species is an iconic component of New Zealand’s unique alpine flora and is valued for its botanical significance.

Garden value:
One of New Zealand’s finest alpine daisies, prized for its bold foliage and spectacular golden flowers. It is best suited to alpine houses, rock gardens and cool-climate landscapes where its natural mountain habitat can be closely replicated. Due to its specialised growing requirements and difficulty in propagation, it remains uncommon in cultivation.
