  • This page gives information about the 2009-2010 bloom for all species in this area, with emphasis on the annuals that are responsible for the widespread showy blooms that appear in some years on the desert floor. (tchester.org)
  • Because the locations change, the numbers of species in bloom, and the number of plants in bloom, cannot usually be directly compared from trip to trip. (tchester.org)
  • I will probably only record the detailed information given in this page as long as the number of species in bloom is relatively few. (tchester.org)
