Key Takeaways
Low maintenance perennials are ideal for Ontario’s climate, coming back year after year with minimal care.
Black-Eyed Susans and Coneflowers thrive in sunny spots, bringing vibrant summer colour.
Hostas excel in shady areas, adding lush foliage where flowers won’t grow.
Daylilies adapt to many soil types and provide weeks of blooms.
Sedum offers drought resistance and late-season colour, perfect for low-water landscapes.
Choosing a mix of these five perennials will give you a garden that’s both stunning and simple to maintain, no matter your gardening experience level.
1. Black-Eyed Susan
Black-Eyed Susans are a garden staple across Ontario thanks to their sunny yellow petals and striking dark centers. These cheerful flowers bloom through much of the summer, often lasting well into early fall.
Once planted, they spread easily and can even naturalize in your garden beds, meaning less replanting and more colour every year.
They prefer full sun but are adaptable to a variety of soils. Aside from occasional watering during especially dry summers, they require very little maintenance.
If you remove spent flowers, they’ll bloom even longer, but it’s not necessary. Their resilience makes them ideal for beginners or busy homeowners who want an easy burst of summer colour.
2. Coneflower
Coneflowers are another excellent choice for an Ontario garden.
Recognizable by their large, daisy-like blooms in shades of purple, pink, and white, they add vibrant colour and attract pollinators like bees and butterflies. They’re especially well-suited for Ontario’s warm summers and can tolerate periods of drought once established.
These perennials thrive in full sun but can handle partial shade as well. Gardeners often leave the seed heads standing through the winter, not only for visual interest but also to provide food for local bird populations.
Coneflowers are a fantastic choice if you want to combine beauty with ecological benefits, as they require little more than an annual trim in early spring.
3. Hostas
If you have shady areas that seem difficult to fill, hostas are one of the best low maintenance perennials you can choose.
Known for their striking foliage rather than flowers, hostas come in endless variations of green, blue, and variegated patterns. Their layered leaves create lush, textured displays that look beautiful in garden beds or along shaded pathways.
Hostas thrive in partial to full shade and are generally very forgiving once planted. They don’t need frequent watering after their roots are established and require minimal care throughout the year.
Every few years, you may need to divide the plants if they spread too much, but otherwise, they’re a “set it and forget it” perennial. They’re especially good for homeowners who want to beautify shaded yards with very little effort.
4. Daylilies
Daylilies are celebrated for their hardiness and reliable blooms. While each flower only lasts for a single day, the plant produces so many buds that you’ll enjoy weeks of colour throughout the summer.
Available in a wide range of colours—from warm yellows to deep reds—daylilies can fit seamlessly into any garden design.
These perennials thrive in full sun but tolerate partial shade and poor soil conditions, making them versatile and easy to grow. Once planted, they need little more than an occasional watering during prolonged dry spells.
At the end of the season, cutting back their foliage helps tidy up your garden for the following year. Their ability to withstand Ontario’s diverse weather patterns makes them one of the most reliable options for gardeners of all skill levels.
5. Sedum
Sedum, also known as Stonecrop, is one of the toughest and most drought-tolerant perennials you can plant.
With its succulent-like leaves and clusters of star-shaped flowers, it thrives in hot, dry conditions where other plants might struggle. Its late-season blooms extend your garden’s beauty into the fall, and its foliage remains attractive long after many other plants have faded.
This perennial loves full sun and well-drained soil, making it perfect for Ontario’s increasingly dry summers.
Once established, it needs virtually no attention. You can cut it back in early spring to encourage fresh growth, but otherwise, it’s one of the most hands-off plants available. Sedum is ideal for those who want beauty in their garden with minimal watering or care.
