Maybe it's because she shares that winning -elle sound with Isabel and Bella, but Estelle is no longer seen as a muumuu-wearing canasta player of a certain age (think George Costanza's mother on Seinfeld or Joey Tribbiani's talent agent in Friends).

Clover is a charming, perky choice if you want to move beyond hothouse blooms like Rose and Lily, and it's recently become a new celeb favorite, chosen by both Neal McDonough and Natasha Gregson Wagner, who used it to honor her mother, Natalie Wood, one of whose most iconic films was Inside Daisy Clover.

As such, she is both the goddess of the Underworld and of Spring.
