 Hyacinthoides non-scripta forms a clade with three other species – H. hispanica, H. paivae and H. cedretorum – centred on the Iberian Peninsula. H. paivae is restricted to a small area of north-western Iberia (Galicia and neighbouring parts of Portugal), while H. cedretorum is found in mountainous areas of western North Africa (Morocco and Algeria). Within Iberia, H. non-scripta and H. hispanica are geographically separated by the Duero river. The genus also contains seven further species, mostly distributed further east in the Mediterranean Basin.
