The plural form of amaryllis; multiple amaryllis flowers or plants.
From amaryllis with the standard English plural suffix -es. Since amaryllis ends in a sibilant sound, the -es ending is used rather than just -s.
English plurals seem simple until you realize different languages do them completely differently—Spanish would say 'amarilis,' French would say 'amaryllis' (unchanged), but English adds -es, showing our Germanic roots.
