Allium longispathum, commonly known as Mediterranean Onion, is a perennial herb native to rocky, dry scrublands and coastal areas in Europe especially along the Mediterranean Basin. This species typically forms clumps reaching 20-50 cm in height. Mediterranean Onion is characterized by its long, slender leaves and tall, sturdy stems that bear umbels of star-shaped, pink to purple flowers during the late spring and early summer months. The flowers are attractive to pollinators and can add a touch of color to the garden landscape.

Mediterranean Onion is valued for its ornamental flowers and its ability to thrive in dry, poor soils with minimal maintenance. It is often used in rock gardens, as border plantings, or in naturalized areas where its drought tolerance is an asset. For optimal growth, it requires well-drained soil, full sun to partial shade, and only occasional watering once established. While it is not commonly known for significant pest or disease issues, onion thrips and downy mildew can sometimes affect the plant. It is also worth noting that Allium species can be toxic to pets if ingested.CC BY-SA 4.0
