Allium sphaerocephalon

Plant in a sunny spot early in autumn, about 15 cm deep in well-drained, slightly moist soil. Clear the area of weeds and debris before planting. Improve the soil with compost or fertilizer to boost nutrition and drainage. Keep the soil evenly moist during the growing season. When the foliage emerges in spring, you can add Zetas bulb fertilizer for extra nourishment. Allow the leaves to die back naturally after flowering.
