             Rubber vine, an invasive introduction                                                                         Episode CCL - 250


              Each week, Island Insight shares with you one story
              of  Aruba  through  the  eyes  of  Etnia  Nativa,  a  native
              venue that welcomes curious visitors to a unique cul-
              tural island experience and connects them with the
              mystical aspects of its native culture and its colonial
              heritage.  Since  that  educational  glance  in  this  epi-
              sode, shares about a poisonous, climbing, invasive,
              but beautiful plant: “Cordon di San Francisco,” an in-
              vasive introduction.

              ent reasons, with characteristics adaptable to our soil
              and our climatic conditions, were introduced. Some
              of  them  originate  from  Madagascar,  a  big  island
              close to the African continent in the Indian Ocean.
