RETURNING BLOOMS
Perennial Plants
What is a perennial? Perennials are plants that have a continuous life cycle and live for more than two years, and often many years.
All perennials have a perpetual rootstock, meaning that the above ground growth dies down in the fall and new growth comes from the root each spring. The root system or bulb (and sometimes the stem and foliage) therefore last through the winter.
This is different from an annual because annuals complete their life cycle in less than one year and the roots die in the winter.
Perennials are easy to grow, require little maintenance and are winter hardy once established. You can find a perennial for almost any situation as there are literally thousands to choose from that bloom at almost any time of the year.
Every garden should have at least a few perennials in them; many gardens almost exclusively contain perennials with little to no annuals. Perennials can be planted amongst evergreens and shrubs for colour in a foundation planting, in a rockery or in a perennial border.
Every year the Perennial Plant Association chooses one plant as their Perennial of the Year. The 2023 Perennial Plant of the Year is the Rudbeckia ‘American Gold Rush’.
Best Perennials for Summer Gardening
Best Perennials for Spring Gardening
At Hunters Garden Centre, these spring perennials are some of the first to arrive and earliest to flower as the weather warms up outdoors.
Best Perennials for Winter Gardening
The beauty of these perennials is that they flower in the winter, providing life and colour to your outdoor garden all year-round! At Hunters Garden Centre we carry these winter-flowering perennials at both our Vancouver and Surrey stores.
Best Perennials for Sun
These perennials will thrive outdoors in a full 8 hours of sun, providing flowers that shine just as bright. Many of these sun-loving perennials attract bees and other pollinators to your garden.
Best Perennials for Shade
Have a difficult area of your garden that doesn’t get much sun? These shade-tolerant perennials can adapt to low light conditions outdoors and still provide your garden with blooms and life year-round.
OUTDOOR PERENNIAL CARE
How to Care for Your Perennial Plants
Perennials grow best in a loose well drained soil. Annual applications of manure in the fall can be dug in the spring to improve soil texture and retain moisture. Plants like to be watered on a regular basis and it is important to cultivate the soil frequently. The small fibrous roots systems grow best in a loose well ventilated soil. Fertilizers should be applied annually. In early spring applications of 6-8-6 encourages new top growth. As plants come into flower, fertilize with a flowering plant food (4-10-10). Taller varieties do require staking. Perennials benefit from winter protection for the first year. Place a mulch 2-3” deep over the plants to protect them from the cold.
Planting
Most perennials are best planted in the spring. Some grow best in the sun, others in shade. Plant perennials as soon as all danger of frost has passed, and the ground is dry enough to work. Make sure to give plants plenty of room so that none of the roots are crowded. The crowns of the plants should not buried, or the plants will suffocate and rot. Some perennials are best planted in the fall. Bearded Iris, Oriental Poppies and Bleeding hearts can be planted in late August. Peonies and Lilies are best planted in September. Shallow rooted perennials such as Chrysanthemums and perennial Asters require a light dressing of soil in the spring. Soil should be applied only around the base of the plants.
If you’re planning a perennial border, a sunny location is best away from encroaching roots of trees or hedges. The border should be at least 6 feet wide to arrange plants properly. Before planting make a plan showing where each variety is to go. Know the height, colour and season of bloom to arrange plants to the best advantage. Plant the tallest plants at the back, then medium tall ones, shorter ones toward the front and ground and prostrate plants at the front edge. A few taller plants can be brought forward to break up the line of the border. Taller plants are best grouped in threes and intermediate and dwarf varieties in groups of five. Plant strong coloured perennials first, leaving adequate space in between for softer coloured perennials.
Watering
Watering thoroughly once or twice a week is preferable to several light watering. Most perennials do not like to have wet roots and excessive wetting of plant foliage encourages disease problems.
Dividing
It is time to divide perennials as soon as plants begin to lose vigour. As a general rule, perennials that bloom in late summer and autumn are divided and replanted in spring, (Chrysanthemums, Asters). Dig up old plants when new growth is 1-2” high. Pull the roots apart to make pieces with three or four shoots. Plant only the most vigorous shoots. Replant and water with a good starter fertilizer such as 10-52-17 or Up Start. Spring flowering perennials (Aubretia, Alyssum, Carpet Phlox) may be divided immediately after flowering in the spring or in August.

FAQs
Hostas are a very hardy, adaptable and easy to grow perennial plant that are grown for their interesting foliage. Flowers are produced on scapes, some are fragrant and they bloom from June to September. They are the perfect plant for those shady garden situations.
Hostas prefer a rich, slightly acid soil enriched with humus to retain moisture.
A fertilizer high in nitrogen will be beneficial and give greater splendor to the foliage.
Hostas are moisture lovers and need regular watering during dry spells and in the summer. Always water immediately after planting!

One of the most common questions from novice gardeners is the difference between an annual and a perennial.
An annual completes their life cycle in less than one year and the roots die in the winter.
Perennials are plants that have a continuous life cycle and live for more than two years, and often many years. As the seasons change, the above ground growth dies down in the fall and new growth comes from the perennial root each spring.
