What Is A Perennial Plant?

It’s easy to get confused with the scientific language used around flowers and plants, especially when it strays into Latin. Sometimes, it’s all Greek to us, but have no fear! This post will take you through what a perennial plant is and some of the most popular choices for your garden, keeping it packed full of colourful flowers right into the winter. 

Tl;dr: In short, perennial plants live for 2 years or longer, and don’t produce wooden stems.

The definition around perennial plants is fairly loose, but botanically a perennial plant is one that lives for 2 or more years. It’s common for plants that grow in beds or borders to be referred to as perennials to differentiate them from trees, shrubs or bulbs. Perennial plants can have foliage that dies in the winter, or it can be evergreen.

A close term to differentiate is a herbaceous perennial. Herbaceous perennial’s stems and flowers die in the winter down to their roots, which stay alive until the next year when new top growth sprouts. They don’t produce wood stems either, setting them apart from plants that live for multiple years such as trees. Some examples of herbaceous perennials are delphiniums and rudbeckia goldsturm.

Perennials can add bright vivid colours to your garden, are great at attracting pollinators and are superb plants to make up borders. So, to make it easy choosing which perennial to add to your garden, here are 5 of the most popular perennial plants.
