Seeds from this outstanding Fishtail palm Caryota mitis or Fishtail palm which is a hardy Fishtail Palm. A native to southeast Asia. Fishtail palms typically form multi-stemmed clumps up to 25 ft high and 12 ft wide. Each slender stem is topped with several bipinnate leaves than can reach 9 ft in length. The light green leaflets are shaped like a fish’s tail fin. Mature plants first begin flowering at the top of the stem. Subsequent flowering proceeds lower and lower down the stem. After the last flowering, the stem dies and should be removed. The clump will survive, however, and continue to produce more stems. Zones 9-11.
