Our Perennial Blooming Calendar

By Erin Robbins

As any seasoned gardener knows, every perennial has a season that it will thrive in. The way to have the most blooms looking their best all season is to know when to plant them. It might seem like a lot to remember each and coordinate your entire garden. To make it easier we’ve made a perennial calendar to keep your garden on track without the stress this year.

Spring

Spring is a transitionary period, the snow turns to rain and the ground begins to wake up. As this year has taught us about spring, one day can be warm and sunshiney and the next could bring a torrent of flurries. For this reason, springtime perennials tend to be smaller and more tolerant of shady weather.

In March, you will see small, low-growing varieties with light colouring, like Crocuses, Lenten Roses (Helleborus), or Daffodils. In April, you will begin to see larger foliage accompanying growing blooms. These include Bergenias, Lily-of-the-Valley, and our springtime favourites, Tulips. May will show off fuller growths, like Primrose, Peonies, and Bugleweed.

These spring perennials offer abundant blooms in lighter shades of whites and blues. Later in the season they will transition into brighter colours, like pink and purple. They pop out of the ground and don’t grow very tall earlier in the season. They will, however, spread nicely, creating a lushness in the garden. As spring progresses, the heights of the perennials will progress, as well. They will enjoy the fresh springtime sunshine, but won’t mind the cloudier days. The harsher summer sun isn’t their favourite, so you’ll see them shy away and go into hibernation as the seasons change.

While the spring season is nearing its later half, you can still add these little perennials to your garden. They will give you something to look forward to next season. They will be your first sign that spring has come when they start to show their colours next year!

Summer

As the sun shines brighter and the days get warmer, spring turns to summer. Summer means bigger, fuller, and more dramatic perennials. Our gardens start to look more sensational and alive. As the sun shines brighter and the days get warmer, spring turns to summer. Summer means bigger, fuller, and more dramatic perennials.

June is perfect for sprouting more vibrant blooms, like Lupines, Sundrops, and Bellflowers. July is best for summer classics, like Delphiniums, Coral Bells, Hostas, and luscious Lilies. August is for full-colour, sun-loving primadonnas, like Chrysanthemums, Asters, and Black-Eyed Susans.

Summer perennials offer the strongest colours and the biggest blooms as they soak up the bright summer sun. They will love as much sun as they can get and healthy watering to feed their Vitamin D addiction.

This is the high season for gardening. With so many perennial varieties to choose from in this season, it’s impossible to name them all. Summer is really a time where you have the most to choose from, so come into the Garden Centre  to see a full selection.

Fall

As the days get shorter and the nights get chillier, flowers start to prepare for their sleepy winter. While most of your garden will wither away in this cold, some late summer bloomers will power through.

Chrysanthemums will begin blooming in late summer, but won’t die with the season. They will stand up against the colder, autumn weather. With these vivacious beauties, you’ll be able to relish the summer right until the frost begins to bite. Autumn Joy will offer the moodier raspberry -red colours to match the changing leaves. They don’t mind the cooler air and will last until the late season, as long as they are not over-watered.

Bugbane is the ultimate fall perennial. It has deep purple tones foreshadowing the darkness of winter-to-come. The light pink and white flowers will sprout in the late summer. Fall will bring more dramatic, dark foliage that will sprout spikes of brown fruit throughout the winter.

A season without much lightness, fall can still promise some greenery as we hold on to the end of the season.
