The Niagara Floral Clock

Forty feet across, free to look at, and the only flower bed in Ontario whose mechanism is maintained by an electricity company.

The Niagara Parks Floral Clock in summer planting, its face spelling NIAGARA PARKS in yellow letters

Photographed on our own tour, July 2026. The face currently spells NIAGARA PARKS in place of numerals. In 1950 it spelled ONTARIO HYDRO, for the same reason: twelve letters, twelve hours.

A power company built a clock out of flowers in 1950, and a power company still services it seventy-five years later. That is the story, and almost nobody tells it.

We stop here on the day tour, between the Whirlpool and Niagara-on-the-Lake. It gets about ten minutes, which is the right amount. What follows is everything worth knowing, with the provenance attached, because the figures published about this thing disagree more than you would expect for a municipal flower bed.

Two keepers, one clock

Niagara Parks horticulture staff and students from the Niagara Parks School of Horticulture grow and maintain the face. The clock mechanism inside the tower is still serviced by Ontario Power Generation, the successor to the Ontario Hydro that built the thing in 1950.

So the flowers and the clockwork answer to different organisations, and have done for decades. It is a small administrative oddity, and it is the reason the clock has kept running through seventy-five years of replanting.

The number nobody agrees on

How many plants are in the face? Niagara Parks, which grows them, says up to 16,000. Niagara Falls Tourism says 15,000 to 20,000. A third published source says more than 24,000.

We would take the operator’s figure, because they are the ones planting it. But the spread is wide enough that any page quoting a precise number without attribution is guessing, and that includes pages that sound very confident.

The claim we are not going to repeat

You will see the Floral Clock described as the largest in the world. Niagara Parks does not say that on its own page. Secondary sources soften it to “one of the largest”. Larger floral clocks exist elsewhere.

Forty feet of planted clock face maintained by two organisations since 1950 is a good enough fact on its own. It does not need a superlative bolted to it, and the same is true of the wayside chapel further up the Parkway, which is widely called the world’s smallest church on the strength of a Guinness record that does not exist.

It is a ten-minute stop on our Niagara day

Between the Whirlpool and Niagara-on-the-Lake, on the Parkway drive. Private SUV from Toronto, licensed guide, seven stops, back at your door by six. $585 flat for up to 5 (about $117 each).

When to see it, and what you get in winter

The planted display runs roughly May to October, and it is redesigned twice within that: violas in spring, then alternanthera and santolina through summer and autumn. Come in July or August and you are looking at the design at its fullest.

Outside the growing season the face is laid out in coloured stones instead. That is worth knowing before you drive out in February expecting flowers. The clock still runs and still chimes, but the picture is a different one. What is and is not running in the cold months is covered in what closes at Niagara Falls in winter.

Where it sits on the Parkway

It is at 14004 Niagara Parkway in Queenston, beside the Sir Adam Beck generating station, which is not a coincidence given who built it. Free parking, free to look at, and it takes ten minutes.

The other stops worth pulling over for on that road are in the Parkway guide, and the full route from Toronto is in the one-day itinerary.

A note on sourcing

Figures above come from Niagara Parks and from published records, not from other tour operators’ pages, and where sources disagree we have shown the disagreement rather than picking one. The hand weights are marked as reported because we found them in one place only.

If you have a primary source for the hand dimensions or an official plant count, we would like it: info@gotourniagara.ca.

Frequently asked questions

How big is the Niagara Floral Clock?

Forty feet, or 12.2 metres, across overall, with a planted face of roughly 38 feet. The face is built on a 3:1 slope so it reads properly from the road, and it is ringed by a water garden about three metres wide, which takes the whole installation to around 26 metres in diameter.

Is the Niagara Floral Clock the largest in the world?

No, and it is worth saying so plainly because the claim circulates widely. Niagara Parks, which operates it, does not make that claim on its own page. Secondary sources hedge to "one of the largest", and larger floral clocks exist internationally. It is a genuinely impressive 40 feet, which needs no embellishment.

How many flowers are in the Niagara Floral Clock?

This depends who you ask, which is why we are quoting a range rather than a number. Niagara Parks, the operator, says up to 16,000 carpet plants. Niagara Falls Tourism gives 15,000 to 20,000. A third published source says more than 24,000. The operator’s own figure is the one we would trust, but the spread is real and anyone citing a precise number should say where they got it.

Who looks after the Floral Clock?

Two different organisations, which is the most interesting thing about it. Niagara Parks horticulture staff and students from the Niagara Parks School of Horticulture grow and maintain the planted face. The clock mechanism itself is still serviced by Ontario Power Generation, the successor to Ontario Hydro, which built the clock in 1950. The flowers and the clockwork have different keepers.

Is it free to visit the Floral Clock?

Yes. No admission, free parking, and it is wheelchair accessible. It sits directly on the Niagara Parkway, so it costs you nothing but the ten minutes to stop. The planted display runs May to October; in winter the face is laid out in coloured stones instead.

What did the original clock face look like?

The 1950 face spelled out "ONTARIO HYDRO", using the twelve letters in place of the twelve numerals. The face is redesigned twice a year and the tower door is opened at times to show the mechanism along with archival photographs of every design since 1950.
