Spanish Bluebell - Invasive Species Information

JKK - High Risk Sign Red 18.gif

Reproduction: Spanish bluebell's seed freely and often hybridize through insect polination.

The Spanish bluebell has hybridised frequently with the native common bluebell and the resulting hybrids are regarded as invasive.

The resulting hybrid Hyacinthoides × massartiana and the Spanish bluebell both produce highly fertile seed but it is generally the hybrid that invades areas of the native common bluebell. This has caused the common bluebell to be viewed as a threatened species.

Spanish & Common  Bluebell Identification

Spanish Bluebell is distinguished from the common bluebell by its paler and larger blue flowers, which are less pendulous and not all drooping to one side like the common bluebell; plus a 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.


Like Hyacinthoides non-scripta, both pink and white flowered forms occur.

Why Is Spanish Bluebell A Problem?

The larger Spanish bluebell can become a problem, not just because of its spreading habit, but also due to its ability to hybridise with the native form. The hybrid forms displace the natives.

As well as the threat of extinction, Spanish bluebells pose to native bluebells, their spread also have knock-on effects for other species.


Native plants and animals evolve together, forming close dependencies and relationships which break down when one is removed or replaced.


The preservation of native plants and animals is crucial to maintaining the variety of life that make Ireland's woodlands and wild places so rich and diverse.
