  • Tidbit
  • The young plants of Pseudopanax crassifolius and Pseudopanax ferox from New Zealand grow spiny leaves to deter what is now an extinct giant flightless bird called a Moa from eating them. Once these small trees grow above about 8 feet tall the leaves change shape and texture to flattened spinless softer leaves. When mature it branches out to form a canopy.
