Taxonomy

There are three varieties that have sometimes been separated out as distinct species or subspecies by some botanists.
  • Convallaria majalis var. keiskei - from China and Japan, with red fruit and bowl-shaped flowers (now widely cited as Convallaria keiskei)
  • C. majalis var. majalis - from Eurasia, with white midribs on the flowers
  • C. majalis var. montana - from the USA, with green-tinted midribs on the flowers


Convallaria transcaucasica is recognised as a distinct species by some authorities, while the species formerly called Convallaria japonica is now classified as Ophiopogon japonicus.
