Summary

Scilla peruviana, commonly known as Portuguese Squill, is an evergreen perennial bulb native to the western Mediterranean region, including coastal areas of Portugal, Spain, and Morocco. It thrives on cliffs, flats, and slopes, often in rocky limestone soils. This bulbous plant has a bulb 6–8 cm in diameter, covered by brown scales. The linear leaves measure 20–60 cm in length and 1–4 cm in width, with 5-15 leaves emerging each spring. The flowering stem stands 15–40 cm tall, topped with a dense pyramidal raceme of 40-100 star-shaped flowers. Each flower is strikingly blue, 1–2 cm in diameter, with six tepals, blooming in late spring to early summer. After flowering, the foliage dies back in summer and re-emerges in autumn.

Portuguese Squill is valued for its vibrant blue flowers that add a splash of color in spring gardens. It is often used in rock gardens, borders, and as underplanting for deciduous trees. While it is not entirely frost-hardy, it can be grown in milder climates or protected during cold spells. For best results, it should be planted in full sun to part shade, with well-drained soil, and provided with low to medium water. It is relatively low maintenance but may require protection from slugs and snails. Cultivars offer a range of colors from white to various shades of blue and violet.CC BY-SA 4.0
