The plant comes from Western Europe. The distribution area covers the north of the Iberian Peninsula, the British Isles, western France and western Belgium. As elsewhere in the western Netherlands and Northwest Germany, the plant is probably feral.
In the Iberian Peninsula and North Africa, the species is replaced by the Spanish hyacinth Hyacinthoides hispanica, which leaves wider (1-1,5 cm) and an erect stem with odorless bell-shaped flowers with blue anthers have.
In Belgium, the wild hyacinth to the west of the line Mechelen, Gembloux, Namur and Meuse.
In the Netherlands, the plant is found mainly in the inner dunes. The plants found in the Netherlands are usually interpreted as being caused by hybridisation of Hyacinthoides non-scripta Hyacinthoides hispanica and which both probably not (anymore) in pure form occur. Although a few local plants can be found in apparently "pure" characteristics of either parent species, it seems preferable to such plants can be seen as the extreme form of perfectly fertile hybrid swarm of the original species.
The plant is pollinated by bumblebees and hoverflies.
The plant is being threatened by two factors:
· Deforestation: The species grows only in old forests because of its large seeds and sows them is only in its immediate vicinity.
· The gardens: By planting in the gardens of the Spanish hyacinth (Hyacinthoides hispanica) occurs to an increasing hybridization.
The powerful hybrid Hyacinthoides × massartiana has wider leaves (1.5 to 4 cm), slightly fragrant, bell-shaped flowers with slightly bluish anthers on a less curved stem. The hybrid is fertile and backcross created numerous intermediate forms. Therefore, there is a real risk that the real species Hyacinthoides non-scripta forward in many places will be lost.
