Ash Creek Ivesia
Ivesia paniculata
  
About Ash Creek Ivesia (Ivesia paniculata) 0 Nurseries Carry This Plant Ivesia paniculata is a species of flowering plant in the rose family known by the common name Ash Creek mousetail, or Ash Creek ivesia. It is endemic to the Modoc Plateau of Lassen and Modoc Counties in the northeastern corner of California, where it is known only from the vicinity of Ash Valley. It was first described in 1981. This is a small perennial herb of sage scrub on volcanic soils and rocky slopes. It forms a matted clump from a woody caudex and produces leaves and stems which lie on the ground or are somewhat erect. Each leaf is about 2 to 5 centimeters long and is made up of rows of many tiny, lobed, pink-edged green leaflets, densely coated in short white hairs. The leaflets overlap such that each leaf is cylindrical. The mostly naked pinkish stems bear inflorescences of hairy clusters of flowers. Each flower is about half a centimeter wide and has hairy pink-edged greenish sepals and tiny pale yellow petals. There are five stamens and a few pistils.
