Perennials plants are annual flowering

Perennials are plants that live for two years or longer and once mature, flower annually.

Herbaceous plants
In gardens, the term perennial applies to herbaceous plants that form flowering stems each year before seeding, then die back in autumn to ground level, sending up new growth in the spring.

Using Perennials plants in containers
A well chosen collection of perennials forms a mixture of textures and colours, both foliage and flowers provide visual interest for months. They can be massed in the traditional herbaceous, featured as specimen plants, or interspersed with shrubs, annuals and biennials in a mixed planter. They can also be cultivated in containers and window boxes.
They range in height from low, creeping plants, useful for ground cover, to feature plants such as the Gunnera manicata which grows to more than 3 metres high.

Perennials are very well suited to beginner gardeners, as well as to the experienced who can design and plant in an endless variety of styles. With perennials, one can be an artist, harmonising colour, form and texture.
