Names and Taxonomy
Comments: De Blaay (2003) reviews the the correct name for this hybrid between Hyacinthoides hispanica (Mill.) Rothm. (Spanish Bluebell) and H. non-scripta (L.) Chouard ex Rothm. (English Bluebell). He outlines an earlier description as Hyacinthoides x massartiana Geerinck, but the Flora of North America names the hybrid as H. x variabilis.
Poindexter et al. (2011) use the name H. x massartiana and cite H. x variabilis in synonymy. These authors note the hybrid bluebell to sold under the alias of 'Spanish Bluebell', and describe it is a rather agressive weed due to its vegetative and sexual modes of reproduction. They also note that the hybrid is becoming well established in many areas and is very likely to be more common than voucher specimens suggest.
