The Amazon Lily or Eucharist Lily (Eucharis amazonica) is hardy in Zones 10 - 11. Prefers shade. Produces deep green leaves to 16" tall with fragrant white flowers that bloom Spring to Late Summer.
University of Florida "Amazon Lily requires shade for its tender leaves and
looks best when grown in rich, moist organic matter. Amazon
Lily should be kept on the dry side during the winter to
stimulate flowering. Amazon Lily can remain undisturbed for
many years, blooming better under crowded conditions, whether
in a pot or in large, outdoor clumps."
