Recommendations for sowing and care: most ornamental onions are best sown before winter on a well-prepared breeding bed.
When sowing in February-March, dig containers with crops into the garden, sprinkle with snow. In the process of gradual thawing of the soil substrate and the passage of melt water through it, the seed coat and the inhibitory layer are destroyed, which prevents rapid germination. When a constant temperature is established within + 5 + 12 ° С, friendly shoots appear.
Onions prefer full sun and well-drained soils with lime added. When propagated by seed, they bloom for 2-6 years. Mature plants reproduce by bulbils or division.
They look great in small groups in rocky gardens, as well as in mixed borders.
