Fall Flowers? How to Incorporate Perennials That Bloom Year-Round

Perennials That Bloom Year-Round

Spring and summer are known for their vibrant blooms and lush greenery. However, the end of summer doesn’t have to mean the end of colour in your garden. Incorporating perennials that bloom year-round allows you to maintain a lively and colourful garden even as the seasons change. This guide is designed to help gardening enthusiasts, from beginners to seasoned green thumbs, understand how to choose and care for perennials that will thrive and bloom throughout the year, including the chilly days of fall and winter. 

What Are Perennials? 

Perennials are plants that live for two or more years, unlike annuals, which complete their lifecycle in a single season. Ideally, you can plant them once, and they will continue to bloom at the same time each year, often growing larger and denser as they establish. The beauty of perennials lies in their ability to bloom multiple times over many seasons, often with less care and maintenance than annuals require. 

What are The Benefits of Planting Perennials? 

  • Stronger: They withstand various weather conditions across multiple years. 
  • Cost-effective: Since they regrow each season, you don’t need to buy new plants every year. 
  • Variety: Perennials come in many shapes, sizes, and colours, offering endless possibilities for garden design. 

What Are the Best Perennials for Year-Round Blooms? 

The thing with plants is there are so many to choose from! But these are a few of our favourite perennials: 

Hellebores (Winter Rose) 

  • Bloom time: Late winter to early spring. 
  • Care tips: Plant in partially shaded areas with well-draining soil. 

Echinacea (Coneflower) 

  • Bloom time: Early summer to fall. 
  • Care tips: Thrives in full sun and tolerates drought once established. 

Sedum (Stonecrop) 

  • Bloom time: Late summer to fall. 
  • Care tips: Prefers full sun and well-draining, poor soil. 


  • Bloom time: Late summer to fall. 
  • Care tips: Best in full sun with average, well-draining soil. 

Heuchera (Coral Bells) 

  • Bloom time: Spring to early summer (foliage year-round). 
  • Care tips: Grows well in both sun and shade; prefers moist, rich soil. 

How do You Incorporate These Perennials into Your Garden? 

Plan Your Garden Layout

When planning your garden, consider the height, colour, and blooming times of your selected perennials. Planning for these factors creates harmony and balance in your garden. Plant taller perennials at the back of your beds, with shorter ones in the front to ensure all plants are visible and get enough light. 

Prepare the Soil

Most perennials thrive in rich, well-draining soil. Amend your garden soil with compost and possibly aggregates before planting to ensure the best growth. 

Ongoing Care

While perennials are less maintenance-intensive, they still benefit from regular care such as pruning, deadheading, dividing when overcrowded, and mulching to retain moisture and control weeds. 

How Often Should Perennials Be Divided? 

Perennials should be divided every three to five years to maintain their health. This process prevents overcrowding, promotes better air circulation, and rejuvenates older plants, encouraging more growth and flowering. Spring and fall are the best times to divide perennials, as cooler temperatures and moist soil help reduce transplant shock and support quick root development. 

When Should I Plant Flowers So They Bloom in the Fall? 

To ensure your garden is vibrant in the fall, plant your flowers in late spring or early summer. This timing allows the plants to establish strong roots throughout the summer, ensuring they are robust enough to bloom beautifully in the cooler fall months. Consider planting species like asters, chrysanthemums, and sedum, which are well-known for their fall blooms. 

Are There Any Flowers That Bloom in the Winter in Ontario? 

Yes, several resilient flowers can bloom in Ontario’s winter. Hellebores, often called Christmas Rose or Lenten Rose, bloom even in freezing temperatures. Winter Aconite and Snowdrops also manage to flower in late winter, offering bright spots of colour in a snowy landscape. Even in cold climates, gardens can thrive with the right care. 

When Should I Plant Spring Flowering Plants? 

Plant spring flowering bulbs, such as tulips, daffodils, and hyacinths, in the fall before the ground freezes. These plants require a cold period underground to stimulate their flowering process in spring. By planting in autumn, you ensure they have enough time to establish roots and gain the necessary chill to bloom beautifully when the weather warms. 

When Should I Plant Flowers for Summer? 

For a colourful summer garden, plant annual and perennial flowers in the spring after the last frost. This allows plants like marigolds, petunias, and coneflowers to settle in before the heat of summer promotes their growth and flowering. Water them regularly as they establish and throughout the summer to encourage continuous blooms. 

What Are Some Native Perennial Flowers in Southern Ontario? 

Southern Ontario boasts a variety of native perennial flowers that are both beautiful and beneficial to local ecosystems. These include the Trillium (the provincial flower), known for its distinctive three-petal flowers; Wild Columbine with its charming red and yellow blooms; and the Butterfly Weed, which attracts pollinators with its vibrant orange flowers. Planting native species supports local wildlife and requires less maintenance, as these plants are well-adapted to the regional climate.
