We recently moved into this new house and have a few of these bushes but I don't know what they are- they're so pretty- maybe someone can help me.

 

Oleander (Nerium oleander). Caution: very poisonous to people, pets, etc., if eaten.

 

Nerium oleander is a small tree or shrubs ever green Mediterranean plant they need
