Snow Butterbur Plant Care

Snow Butterbur (Petasites nivalis) belongs to the Asteraceae family within the Petasites genus. Snow Butterbur is native to Arctic to cool temperate regions of the Northern Hemisphere in northern Europe, northern Asia and northern North America. Snow Butterbur is also known as Nardosmia angulosa, Nardosmia corymbosa, Nardosmia frigida.

Snow Butterbur displays a large spreading perennial growth habit, reaching up to 3 ft tall with a spread of approximately 5 ft. Snow Butterbur produces large, showy pink or white flower clusters.

Leaf size: approximately 12 inches.

Petasites nivalis requires watering every 3–5 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Snow Butterbur thrives in partial shade to full shade. The optimal light range is 100–500 lux. Avoid placing Snow Butterbur in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Petasites nivalis grows best at temperatures of 50–75°F. Snow Butterbur prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, moist soil with good drainage. Good drainage is essential for Snow Butterbur to prevent waterlogging, which leads to root rot and fungal issues.

Feed Snow Butterbur every 6 months during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Divide and repot every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Snow Butterbur can be propagated through division, rhizome cuttings. Similar propagation techniques also apply to white butterbur plant care, which shares the same genus.

Snow Butterbur is susceptible to slugs, snails, powdery mildew. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Snow Butterbur grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Snow Butterbur is native to Arctic to cool temperate regions of the Northern Hemisphere in northern Europe, northern Asia and northern North America. In cooler regions, grow Snow Butterbur as a houseplant or bring it indoors before the first frost.
