Coneflowers (Echinacea) have earned their place in perennial borders, pollinator gardens, and meadow-style landscapes—and for good reason. These hardy, vibrant perennials reliably return each spring in our Ontario Zone 6 climate, adding long-lasting colour and texture to any garden.
The classic Purple Coneflower (Echinacea purpurea) begins with soft, pink-tinged petals that deepen into rich purple hues as the season progresses. At its peak, the familiar domed centre cone emerges—an eye-catching structure that dries beautifully and provides winter interest in the garden.
Purple Coneflower (Echinacea purpurea)
Choose From The Rainbow
While the purple coneflower is the most iconic, hybrids now come in nearly every colour of the rainbow. You'll find stunning varieties in pink, white, green, orange, and fiery reds.
Rudbeckia hirta 'Cherokee Sunset'
Rudbeckia hirta 'Double Gold'
Echinacea 'Snow Cone'
No matter your garden’s colour scheme, there’s likely a coneflower to match. Even better, their bold blooms attract pollinators like bees and butterflies, while the seed heads feed songbirds in fall and winter.
Low Maintenance, Long-Blooming Beauty
Coneflowers are both showy and easy to care for—ideal for beginners and seasoned gardeners alike. Here’s what you need to know:
Growth habit:
- Height: 24–60 inches, depending on the variety
- Spread: 12–24 inches
- Bloom time: Mid-summer to fall
Growing conditions:
- Sun: Full sun is best, though light shade is tolerated
- Soil: Well-drained soil is key
- Water: Drought-tolerant once established, but thrives with consistent watering
- Fertilizer: Not necessary
Pro tips for success:
- Pinch back in early summer to encourage bushier, sturdier plants and decrease the chance of powdery mildew forming
- Deadhead spent blooms early in the season to prolong flowering
- Leave seed heads in late summer and fall for winter beauty and bird food
- Optional self-seeding: Let them go to seed for a naturalized look, or remove blooms to prevent self-seeding
Coneflower Companions
Coneflowers mix beautifully with a variety of other perennials. For vibrant, complementary plantings, try pairing them with:
- Hyssop (Agastache)
- Catmint (Nepeta)
These companions share similar growing requirements and will enhance the colour and texture of your garden throughout the growing season.

What’s the best way to brighten up your garden? Add lots of annual flowers in the Spring! Here in Southern Ontario, the May holiday weekend is usually safe from frost - and go time for planting tender annuals!
At Eising Garden Centre, you’ll find a wide array of beautiful annual blooms. Here are ten of our sun-loving favourites to try.
Cosmos
With daisy-like blooms in radiant shades of pink, red, and pure white adorned with mellow yellow centres—Cosmos are irresistible. They're perfect planted along a fence or at the back of a border, where they can lean on a little support. Depending on the variety, Cosmos can grow anywhere from 12 to 80 inches tall!
Zinnia
Bold, structured, and bursting with colour, Zinnias bring serious wow factor. Their cheerful blooms come in red, green, orange, yellow, purple, pink, and white. Depending on the variety, Zinnias grow between 6 and 36 inches tall and spread about 12 inches wide.
Calendula
Decorative and useful, Calendulas are edible flowers with culinary and medicinal value. Their soothing, antiseptic properties make them popular beyond the garden. Calendula come in gorgeous, bright shades of copper, orange, gold, and yellow blooms and grow 10 to 24 inches tall.
Marigold
Tough and reliable, Marigolds handle heat and humidity with ease, thriving even in the driest parts of your garden. They offer a beautiful range of bloom types—from large, ruffled flowers to small, delicate blossoms—and a palette of cream, yellow, orange, red, and bi-colours. Depending on the variety, Marigolds can grow from 6 to 36 inches tall.
Amaranth
If you're after drama, Amaranth is your plant! Reaching heights of 3 to 5 feet, these bold beauties flaunt long, rope-like clusters of maroon or red flowers. While low-maintenance, Amaranths may need a bit of support to stay upright as they mature.
Portulaca
Perfect for hot, dry, and neglected spots, Portulacas deliver a brilliant show of colour with minimal effort. Their rose-like blooms come in vivid shades of red, pink, yellow, white, orange, and purple. Low-growing at just 4 to 8 inches tall, they're ideal for the front of borders, or alongside driveways, and patios.
Salvia
With tall spikes of bold purple, red, blue, pink, or white blooms, Salvias are garden standouts. Growing 8 to 24 inches tall and often blooming continuously, they quickly become must-haves for flower beds or large containers.
Geranium
Drought-tolerant and tough as nails, Geraniums have long been a gardener’s favourite. Regular deadheading (removing spent blooms) will reward you with non-stop flowers until frost. Their lush foliage and bright flowers—ranging from salmon, white, purple, violet, and orange to red and pink—also shine in mixed containers. Geraniums typically grow between 8 and 24 inches tall.
Petunia
It’s no surprise Petunias have remained beloved for generations. They grow quickly, bloom prolifically, and require little care. Available in mounding or trailing forms—and sometimes carrying a heavenly scent—Petunias are perfect for flower beds, hanging baskets, pots, or window boxes. Growing 6 to 18 inches tall, they come in white, yellow, pink, purple, red, bi-colours, and even black!
Dahlia
Dahlias can become a full-on passion project—and it’s easy to see why. Their breathtaking blooms come in a stunning range of sizes, shapes, and colours. While Dahlias can be a bit particular (they love rich, well-drained soil and plenty of water, but hate soggy conditions), they are absolutely worth the extra attention.
Sunshine + Food + Hydration = Success
All of these annuals thrive in full sun and will reward you with even more blooms when given consistent water and fertilizer.
Adding a continuous-release fertilizer to your soil at planting time—or feeding weekly with a balanced, water-soluble fertilizer—makes it easy to keep your garden thriving all summer long!
