Are the spider lilly and the cluster amaryllis(higanbana) the same flower or just similar looking?
The red spider lily and the cluster amaryllis are identic plants! The nomenclature of these names is a bit complicating, because spider lily is not a species of Liliaceae ( Lily family ), but an Amaryllidaceae ( Amaryllis family ): Scientific name of spider lily is Hymenocallis caribaea http://cms.jcu.edu.au/discovernature/pla… Higanbana is the red spider lily, Lycoris radiata The english common name “cluster amaryllis” is – after botanical aspects – the correct one.
