Yadon's Rein-orchid
Piperia yadonii
About Yadon's Rein-orchid (Piperia yadonii) 0 Nurseries Carry This Plant Piperia yadonii, also known as Yadon's piperia or Yadon's rein orchid, is an endangered orchid endemic to a narrow range of coastal habitat in northern Monterey County, California. In 1998 this plant was designated as an endangered species by the United States government, the major threat to its survival being continuing land development from an expanding human population and associated habitat loss. One of the habitats of Yadon' Piperia, the Del Monte Forest near Monterey, California, is the subject of a federal lawsuit, based upon endangerment of this organism along with several other endangered species. This wildflower may lie dormant in a given year and not emerge above the soil surface from its tuberous substructure. After leafing out in the spring, it will produce flowers on erect spikes, each flower possessing both green and white petals. It prefers sandy soils, and subsists on nutrient extraction from intermediate fungal organisms. Yadon's piperia is confined to a handful of locations in the coastal area of north Monterey County primarily the Del Monte Forest on the Monterey Peninsula.
