Did you know

  • The tiny white flowers spiral around the stem like a braided tress of hair, giving the orchid its poetic common name.
  • It is one of the last orchids to bloom in the European year, often flowering in September and October.
  • Lady's Tresses is a mycorrhizal orchid that depends on specific soil fungi to germinate and grow, making it difficult to cultivate.
  • The spiral can twist either clockwise or counterclockwise, and both directions can appear in the same population.
  • Despite being widespread, it is declining across Europe due to the loss of old, unimproved grasslands to modern agriculture.
