The Spanish Bluebell (Hyacinthoides hispanica, syn. Endymion hispanicus or Scilla hispanica), is a spring-flowering bulbous perennial native to the Iberian Peninsula. It is one of three species in the genus Hyacinthoides, the others being the Common Bluebell (Hyacinthoides non-scripta) in northwestern Europe, and the Italian Bluebell (Hyacinthoides italica) further east in the Mediterranean region.
It is distinguished from the Common Bluebell by its paler, larger blue flowers, more erect flower stem (raceme), broader leaves, blue anthers (where the Common Bluebell has creamy-white ones) and little or no scent compared to the strong fragrant scent of the northern species.
The Spanish Bluebell is introduced in the United Kingdom, where it has become an invasive species. The two species hybridise freely, and the resulting hybrid Hyacinthoides × massartiana and the Spanish Bluebell both produce highly fertile seed and can invade areas of the native Common Bluebell. This has caused the Common Bluebell to be viewed as a threatened species.
The Spanish Bluebell is also cultivated as a garden plant, and several named cultivars exist with flowers in various shades of white, pink and blue.
