Grandparents' Day flowers are a warm, uncomplicated way to thank the people who spoiled you first. The holiday lands on Sunday, September 13, 2026, and the season points to specific blooms: in-season Ontario asters and dahlias, plus pink or yellow roses that read as gratitude rather than romance. The official flower is the forget-me-not, though it rarely appears fresh this late in the year. A hand-tied bouquet, left at the door, can say thank you when the right words are hard to find. Cindy's Flowers hand-ties bouquets like these in its Toronto studio and delivers across Toronto and the GTA Monday to Saturday, so for a Sunday holiday, aim for delivery on Saturday, September 12.
When is Grandparents' Day 2026?
Grandparents' Day 2026 falls on Sunday, September 13. In Canada, the holiday has been marked on the second Sunday of September since 1995, when the House of Commons passed Motion 273, introduced by MP Sarkis Assadourian. The United States sets its own date as the first Sunday after Labor Day. Because Labor Day 2026 is Monday, September 7, both countries land on the exact same Sunday this year.
The origin is genuinely touching. A West Virginia woman named Marian McQuade spent years campaigning for a day to honour older family members, and President Jimmy Carter signed the proclamation into effect on August 3, 1978. It's a young holiday by tradition's standards, but the impulse behind it is old: set aside one day to notice the people who quietly held a family together.
One practical note before you plan. September 13 is a Sunday, and we deliver Monday through Saturday. The easy fix is to have flowers arrive on Saturday, September 12, so the weekend still opens with something beautiful on the table.
What is the official flower for Grandparents' Day?
The forget-me-not is the flower most associated with the holiday, and its name explains why. By floral convention, the small blue Myosotis stands for remembrance and true, enduring love, which is about as fitting a message for a grandparent as flowers can carry. There's one catch. Forget-me-nots bloom in spring, so you'll almost never find them fresh at a September florist.
That's why the tradition has always been forgiving. Seasonal flowers are given in the forget-me-not's spirit rather than to the letter, which leaves you free to choose blooms that are genuinely at their best in mid-September. The sentiment counts for more than the species. If you like the idea of that blue, ask for a few blue accents worked into a seasonal arrangement, a quiet echo of the original flower.
Which flowers are best for Grandparents' Day?
For a September gift in Ontario, the smartest picks are the ones in season right now. Asters and dahlias both peak locally in early autumn, so they arrive fresher and last longer than anything shipped in from another climate. Here's where local seasonality actually pays off, not just as an eco talking point, but in vase life you can see.
- Asters are September's birth flower. The name comes from the ancient Greek word for "star," after the star-shaped bloom, and by convention asters carry meanings of wisdom, faith, love and patience. The New England aster is native to southern Ontario and keeps flowering into September and October, so it's a genuinely local choice.
- Dahlias hit their stride once the nights cool. Across southern Ontario they bloom from mid-summer until the first hard frost, usually peaking in September, which makes them a bold, seasonal centrepiece.
- Chrysanthemums are the classic autumn cut flower. One caveat is worth knowing: in China and Japan they symbolize longevity and rejuvenation, while in parts of Europe they're tied to mourning, so their meaning depends on the person receiving them.
- Morning glory is September's other birth flower. It's better known as a climbing garden vine than a cut stem, but it's a sweet nod if you're gifting something to plant.
A quick myth to retire: peonies are not a local September flower. In the Toronto area, garden peonies bloom once a year, roughly late May to late June. Any peony you spot in September has been imported from Holland or Chile, so it's lovely, but not in-season here. If you want that lush, layered look for the holiday, a mixed bouquet built around seasonal blooms gives you the same generosity with flowers actually at their peak.
What colour roses say "thank you" to a grandparent?
Colour does quiet work in a bouquet, and for a grandparent you want warmth over romance. By convention, pink roses convey gratitude, admiration and a gentle grace, while yellow roses stand for friendship and joy. Both are ideal for saying thank you. Red roses traditionally signal romantic love, so they send the wrong note here.
Think about the room the bouquet will live in, too. A soft, muted palette suits a calm sitting room, while brighter tones lift a kitchen table where the family gathers. You needn't stop at roses either. Pair soft pink blooms with those in-season asters, or build a sunny arrangement around yellow and gold for a grandparent who likes a bright room. And if the day happens to double as a grandparent's birthday, the same warm palette carries the celebration without looking like it came off a template.
More than one Sunday: flowers as an everyday thanks
You don't need a date on the calendar to send a grandparent flowers. Some of the most appreciated deliveries turn up for no reason at all, on an ordinary Tuesday, saying "I was thinking of you" more plainly than any occasion ever could. That's the whole appeal of a just-because bouquet: a small, unprompted kindness that tends to mean the most. Grandparents in particular often live for the small check-ins between the big holidays, and a mid-week bouquet turns an ordinary phone call into something they can look at all week.
The logistics are easy for Toronto and GTA families. Cindy's Flowers hand-ties every arrangement in our Toronto studio and delivers same-day when you order before 3 PM, Monday through Saturday, from Etobicoke and Scarborough out toward Markham. You can browse the current bouquets and match the flowers to the grandparent, from quiet and classic to bright and generous.
What should you write on the card?
The flowers open the door, but the card is what gets kept. You don't need a famous quote, just something specific. A line that names a real memory, like "thank you for every Sunday dinner," lands harder than any borrowed verse. If you're stuck, a few honest sentiments rarely miss:
- "Thank you for everything you've taught me."
- "You make our family what it is."
- "Thinking of you today, and always."
Keep it in your own words where you can. Grandparents tend to save cards, and the ones they reread are the slightly imperfect, heartfelt ones, not the polished greeting-card lines.
How do you keep a Grandparents' Day bouquet fresh?
A good bouquet should still look happy two weeks in, and the care is refreshingly simple. When the flowers get home, recut an inch or two off each stem at an angle, then use the flower-food packet: it pairs sugar for energy with an acidifier that helps the stems drink and an antimicrobial that keeps the water clean. Change that water every two or three days.
Two things quietly cut a bouquet's life short. One is heat and direct sun. The other catches people off guard: a nearby fruit bowl. Ripening apples, bananas and pears release ethylene gas, which speeds up wilting, so keep the vase well clear of the counter fruit. A cool spot out of a heating vent or afternoon window will always beat a warm, sunny sill.
A safety note if a cat lives in the home. True lilies and daylilies are highly toxic to cats, and every part is dangerous, from the petals and pollen to the vase water itself. Swallowing even a small amount can cause fatal kidney failure within days. When there's a cat around, skip lilies altogether and lean on roses, asters or dahlias instead. For the full routine, our guide to caring for a mixed bouquet covers every step.
