From Wikipedia, the free encyclopedia
A
perennial plant or
perennial (
Latin per, "through",
annus, "year") is a
plant that lives for more than two years.
[1] When used as a
noun, this term applies specifically to perennial
herbaceous plants, even though
woody plants like
shrubs and
trees are also perennial in their habit.
Perennials, especially small
flowering plants, grow and bloom over the spring and summer and then die back every autumn and winter, then return in the spring from their
root-stock rather than seeding themselves as an
annual plant does. These are known as
herbaceous perennials. However, depending on the rigors of local climate, a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings or from divisions.
