About Round-headed leek
Allium rotundum, also known as Round-headed Leek or Ail arrondi, is a wild Allium distinguished by its dense, globular umbels of purplish-pink flowers that appear in early summer. This perennial bulbous plant reaches 30 to 60 cm (1 to 2 feet) in height, making it ideal for rock gardens, borders, or naturalized meadows where a rustic and wild touch is desired. Its flowers attract pollinators and add unique visual interest to the landscape.

Care tips
It prefers full sun to light partial shade and well-drained soils, although it is quite adaptable. Watering should be moderate during flowering, reducing once the leaves begin to yellow. It is crucial to avoid waterlogging, as the bulbs are susceptible to rot in wet soils. A common mistake is planting it in deep shade, which will result in sparse or no flowering.
