How to plant
When to Plant
Plant Eranthis tubers in late summer to early fall, before the ground freezes. Cooler regions benefit from earlier planting to give roots time to establish.
Where to Plant
Choose a location with full sun to light shade. Since Eranthis blooms early, it benefits from bright light before trees leaf out. The soil should be moist but well-draining — avoid soggy areas.
Preparing the Soil
Loosen the soil to a depth of 10 to 15 cm and remove stones or compacted clumps. Improve heavy soil with compost or leaf mold to increase drainage and nutrient content.
Planting the Tubers
Place tubers with the flat base down or on their side if orientation is unclear. Plant them 5 to 8 cm deep and about 7 to 10 cm apart. For a more natural look, group them in small drifts.
After Planting
Water gently after planting to help the soil settle. During the cooler season, rainfall usually provides enough moisture, so avoid overwatering.
Spring Growth and Flowering
Bright yellow flowers emerge in late winter or early spring. Leaves will follow, feeding the tuber before dying back by early summer.
After Blooming
Allow foliage to die back naturally. Once it has fully withered, the area can be cleaned up. Over time, Eranthis will multiply and form larger colonies. Divide clumps only during dormancy, if needed.
Extra Growing Tips
Eranthis thrives under deciduous trees, in rock gardens, or borders with good spring sunlight. They’re beautiful planted with snowdrops and crocus. Due to their toxicity, plant away from pets or edible beds and wear gloves when handling.
