Did you know

  • Each flower truly lasts only a few hours, opening in the morning and wilting by midday, hence its evocative common name.
  • The papery, inflated seed pods are translucent and look like miniature Japanese lanterns, persisting long after petals drop.
  • The dark purple-black center of the flower creates a dramatic bulls-eye pattern that guides pollinators to the nectar.
  • Despite being a hibiscus, it is a small, modest annual rather than the large tropical shrub most people associate with the genus.
  • It has become a widespread weed in agricultural areas across North America and Australia, arriving as a contaminant in crop seed.
