Sowing: Seeds are best sown as soon as they ripen (May to July) or in autumn or spring. Seeds can also be soaked in warm water overnight before planting.
Notes: The plant typically grows 15-30 cm (6-12 inches) tall and spreads by rhizomes and self-seeding, creating beautiful drifts in suitable environments. The foliage emits a strong onion/garlic-like aroma when bruised. Its early blooms are an important nectar and pollen source for bees, butterflies, and other pollinators. Wild garlic is also said to repel cats.
Soil: Prefers moist, fertile, and well-drained loamy soils. Adding grit to clay soils can improve drainage.
Habitat: Thrives in full to partial shade, preferring woodland conditions with indirect bright light for at least 6 hours.
Soil pH: Mildly acidic to neutral or even mildly alkaline.
Moisture: Prefers moist, evenly watered soil but should not be waterlogged. Can tolerate limited drought once established, though foliage may suffer.
Germination: For indoor sowing, cold stratification is often beneficial: keep seeds warm (18-22°C or 64-72°F) and moist for 2-4 weeks, then cold (–4 to +4°C or 25-39°F) for 4-6 weeks, before returning to a cooler temperature (5-12°C or 41-54°F) for germination.
Propagation: Seeds are best sown as soon as they ripen (May to July) or in autumn or spring. Division of bulbs in summer after the plants have died down is another easy propagation method.
Additional Notes: This species dies down in early summer and goes dormant until late winter; reduce watering during this period. It can spread aggressively by rhizomes and self-seeding, forming large colonies, so its spread.
