 Naturalization in Belgium
First observation in the wild: |
1882 |
Invasion stage: |
spread |
Spatial distribution: |
restricted |
 Invasiveness
Reproduction in the wild: |
yes |
Dispersion potential: |
medium |
Natural habitats: |
high |
More on invasiveness: Widely dispersed by horticultural activities, Hyacinthoides hispanica and H. x massartiana may escape in the wild in the vicinity of planted populations in parks and gardens. Seed or bulb dispersion is rather limited but pollen may be disseminated over distances exceeding 1 km. They thrives in similar environmental conditions than the native bluebell H. non-scripta, i.e. damp and nutrient-rich deciduous forests. Those plants are increasingly observed in the wild.

More on impacts: The Spanish bluebell H. hispanica may easily produce fertile hybrids (H. x massartiana) with native bluebells (H. non-scripta). Due to low habitat differentiation, it may pose a significant risk to the survival of the native species by assimilation and introgression processes. Field observations along the Belgian coast also suggest that the more vigorous Spanish bluebell may potentially outcompete the native one.
