H. × massartiana fills a spectrum of variation which connects the two parental species.

[1] Hyacinthoides × massartiana has become widespread across Britain and Belgium,[2] both of which have large populations of H. non-scripta.

It is often found on the edges of woodland and roadsides, particularly in urban areas, suggesting that it has spread from gardens planted with H.

[3] There is great concern over the effect that the hybrid may have on native H. non-scripta populations, diluting the characteristics of the native species and out-competing it due to H. hispanica's robust fertility and the effects of climate change.

[7] The same taxon had already been given the name "Hyacinthoides × variabilis" by P. D. Sell in 1996 in the Flora of Great Britain and Ireland,[8] but without a valid Latin diagnosis.
