There are two varieties, ''Lilium bulbiferum'' var. ''croceum'' (Chaix) Baker in the Western part of the range, and ''Lilium bulbiferum'' var. ''bulbiferum'' in its Eastern part. Only the last one always produces secondary aerial bulbs (''bulbils'') in the axils of the upper leaves. These ''bulbils'' fall to the ground and mature after two to three years. When manually separated from the stem they can easily used for propagating the plant.
The dwarf plants from the Maritime Alps, formerly described as var. ''chaixii'' (Elwes) Stoker, and the large plants from the region of Naples, formerly described as var. ''giganteum'' N. Terracc., are now considered as local variants of var. ''croceum''.
