Perennial (n) - existing for a long or indefinite time, continually recurring

Perennials, also known as herbaceous perennials or Herbaceous plants, live for a minimum of 2 years, often for many seasons. Perennials, grow and bloom over the spring and summer, and generally die back every autumn and winter, reappearing on the same rootstock the following spring. Some perennials keep their leaves all year round and offer attractive borders and ground-covers.
