Allium lusitanicum, commonly known as the Portuguese Allium, is a bulb-forming perennial herb native to a variety of habitats including meadows, rocky slopes, and scrublands across mountainous regions of Europe, from Portugal to Ukraine. It typically grows to a modest height of up to 8 inches (20 cm) and produces thread-like leaves that are often shorter than the flowering stalks. The plant is adorned with attractive rose-violet flowers, which are arranged in umbels, blooming in the summer months and adding a splash of color to the garden landscape.

Portuguese Allium is valued for its ornamental flowers and is frequently used in rock gardens, borders, and as a part of naturalistic plantings. It is also suitable for xeriscaping due to its low water requirements. In cultivation, it prefers well-drained soils and thrives in full sun exposure. While it is generally low-maintenance, it can be susceptible to onion fly and thrips. Gardeners appreciate this species for its ability to naturalize and its resistance to deer and rabbits.CC BY-SA 4.0
