Amaryllis
If you're looking for a showier flower name than Lily, but staying in the same botanical family, you might consider Amaryllis, which is not as outre as it might at first sound. It was used in Greek poetry as the appellation of pure pastoral beauties; Amaryllis is the heroine of Virgil's epic poem Ecologues, after whom the flower was named. Other references are characters in the George Bernard Shaw play Back to Methuselah and The Music Man. James Bond-creator Ian Fleming had a half sister named Amaryllis Marie-Louise Fleming, who was a noted British cellist.
