The Story
Plant Bio
Harperocallis flava, or Harper's Beauty, is a rare, federally endangered herbaceous perennial native to the Florida panhandle. It features grass-like leaves and a single, bright yellow, six-petaled flower on a leafless stalk. This species is highly specialized, growing only in acidic, nutrient-poor, sandy seepage bogs. Its rarity and specific habitat requirements make it a significant plant for conservation, not for general horticulture.
