Are both Nerium or Thuja could be a shrub?
Nerium Nerium oleander is a shrub or small tree in the dogbane family Apocynaceae, toxic in all its parts. It is the only species currently classified in the genus Nerium. It is most commonly known as nerium or oleander, from its superficial resemblance to the unrelated olive "Olea". It is so widely cultivated that no precise region of origin has been identified, though southwest Asia has been suggested. The ancient city of Volubilis in Morocco may have taken its name from the Berber name "oualilt" for the flower. Oleander is one of the most poisonous commonly grown garden plants.
Tara spinosa Tara spinosa, commonly known as tara (Quechua), is a small leguminous tree or thorny shrub native to Peru. "T. spinosa" is cultivated as a source of tannins based on a galloylated quinic acid structure. This chemical structure has been confirmed also by LC-MS. It is also grown as an ornamental plant because of its large colorful flowers and pods.
