Why Choose Seasonal Ontario-Grown Flowers?
Choosing flowers that are naturally blooming near your wedding date has several advantages.
More Flowers for Your Budget
Flowers that are naturally abundant during their peak season can offer excellent value, particularly when purchasing flowers in bulk for DIY arrangements.
Beautiful, Fresh Flowers
Locally grown flowers can be harvested close to your wedding date rather than travelling thousands of kilometres through the traditional floral supply chain.
More Interesting Varieties
Local flower farms can grow varieties that aren't always practical for large-scale shipping.
That means your wedding flowers might include unusual dahlias, specialty tulips, delicate cosmos, grasses, flowering herbs and other varieties you won't necessarily find in a typical grocery-store bouquet.
A Natural Ontario Wedding Look
Seasonal flowers naturally reflect the time of year you're getting married.
A June wedding might feature peonies and delicate garden flowers, while a September wedding could feature dahlias, cosmos and ornamental grasses.
Instead of trying to make every wedding look the same, seasonal flowers allow the season to become part of your wedding design.
Don't Plan Around One Exact Flower
One of the most important things to understand about locally grown wedding flowers is that nature controls the schedule.
A warm spring can make flowers bloom earlier. A cool spring can delay them. Summer heat, rainfall and the timing of the first fall frost can all affect availability.
That's why we recommend thinking about your flowers in terms of colour, shape, texture and overall style rather than requiring one specific variety.
For example, instead of planning your bouquet around one particular white flower, you might ask for a mix of seasonal white and soft-green flowers with a romantic garden style.
That gives your flower farmer flexibility to select what's looking its best when your wedding arrives.
Planning DIY Wedding Flowers by Season
A simple approach is to start with your wedding month and then build your flower plan around what's naturally available.
Choose a general colour palette. Decide whether you prefer a romantic, colourful, wildflower, garden-inspired or more traditional look. Then estimate how many bouquets, centrepieces and other arrangements you'll need.
From there, you can select bulk flowers that provide a good balance of:
- Focal flowers
- Supporting flowers
- Filler flowers
- Flowers that add movement
- Greenery and foliage
This approach gives you enough variety to make your arrangements interesting without making the DIY process unnecessarily complicated.
