Some of my favourites:

Located in Grey-Bruce County, Larkwhistle is probably one of Ontario's best private gardens. 

Winters on the Bruce Peninsula and long and harsh. The marginal topsoil is thin and sandy. 

Despite these challenges, noted garden writer Patrick Lima and his partner, the photographer John Scanlan, have managed to create magical garden full of color. The garden was once open to the public, but it's owners have recently retired. You can still visit Larkwhistle Garden in this series of posts: Part 1 and Part 2.

This garden combines conifers, deciduous trees, shrubs and perennials in a truly masterful way. In Part 1 there is a general overview of the garden. In Part 2 we look at some of the artful plant combinations and in Part 3 we look at conifers and the way they are combined with other plants.

A Secret Garden

In a word, Carole's garden is stunning! There are 3 posts: Part 1 presents an overview of the garden, Part 2 tours at the pond and shade garden and the Part 3 looks at the amazing backyard.

One of the great advantages of laying out a garden on a slope has been the ability to look down on the garden from on high. Jacquie found herself looking out her window at the as yet untouched expanse of grass in the backyard:"I'd sit upstairs by my living room window and plan where to dig the next garden patch. When that project was finished, I'd do the same thing until the whole garden was mostly the way I wanted it."
See the how Jacquie's garden came together in a two part series of posts: Part 1 and Part 2.

There is an enviable view of a lake which sparkles through evergreen trees at the back of the home of Duff and Donna Evers. There is a short plateau of land with a deck and then the property rolls down in a gentle incline to a lake. In a series of three posts, you can visit their spectacular garden filled with blooming rhododendrons, azaleas, a collection of magnolias trees and spring flowering perennials. Part1: The Lakefront Terrace Garden, Part 2: The Upper Terrace and Lakefront, Part 3: The Woodland and the Gate of Lost Marbles

Landscape architect David Tomlinson, designed and began work on his beautiful garden in 1981. On the 3/4 of an acre that surrounds his home in Aurora, Ontario, David set out to create a series of gardens within a garden. There is a Perennial Flower Garden, a Fragrant Garden, a Rock Garden and a Winter Garden.

Visit David Tomlinson's garden in early spring in this blog post and in June in this blog post.

Each year, David Tomlinson opens Merlin's Hollow to the public free of charge on the 2nd Saturday in May, the 2nd Saturday and Sunday in June and the 1st Saturday in July and the Sunday of the following weekend.

Beautiful Tapestry

In her lovely garden, Heather Bradley has woven a rich tapestry using shape, color and texture. Flowers are not the focus. They are just one of the many elements.

Take a stroll down the moss covered paths in this blog post.

The Rock Garden in Truro Nova Scotia: When Dr. Bernard Jackson retired to Truro, Nova Scotia after spending 22 years as the Director of the Memorial University Botanical Garden in St. John's Newfoundland, he was approached by the Agricultural College in Truro to create a new rock garden for their campus. 
A series of three posts looks at the garden Dr. Jackson created with a team of staff and volunteers. The series also offers planting notes on rock garden and alpine plants as well as advice from Darwin Carr, the Operational Manager for the grounds at the Dalhousie University campus. The final post in the series takes a look at the garden's collection of conifers and notes creative ways to incorporate texture into any garden. The Rock Garden Part 1, Part 2: Planting Notes, Part 3: Creative Ways to use Texture.

Gardens in the Greater Toronto Area:

Every year, Through the Garden Gate offers local garden enthusiasts a chance to peak into some of the Toronto's finest private gardens.  In this blog post see two gardens in the exclusive Rosedale neighbourhood in downtown Toronto.

Though it seems to hail from a bygone era, the first garden and ivy covered house in this post actually dates from the late 1930's. 

The second home and garden puts me in mind of a summer party in a Jane Austin novel.  I can imagine ripe strawberries and champagne as part of an elegant, but casual afternoon tea or perhaps a more grand affair with a big tent erected on the lawn, tables laid with crisp, white linen and fresh flowers, women in flirty summer dresses and men in light summer suits.

This garden was my personal favourite on the 2012 Through the Garden Gate tour. Visit this tradition garden in downtown Toronto. 

This garden in the Forest Hills area of Toronto incorporates a swimming pool into the garden in a tasteful way.

An Old World Garden

Though it is set in the centre of a big Canadian city, this garden feels private and remote. The atmosphere is decidedly Old World. 

The Toronto Islands is a crescent-shaped cluster of small islands in Lake Ontario just off-shore of downtown Toronto. There is no bridge to the islands. If you want to go there, you must travel by ferry. In this two part series, you can hop the ferry and tour a of few of Ward Island's many incredible gardens: Part 1 and Part 2.

A Sunken Garden

One of my personal favourites: the front garden is a ivy covered courtyard and lotus-filled pond. The backyard is a shade garden in a ravine setting.

A Walled Garden of Peonies and Roses
Many of the gardens on the 25th anniversary Through the Garden Gate tour in 2012 were designed and planted by professionals. They were fabulous, but often somewhat impersonal. This garden was different. The design and the choice of plants all had a definite personality behind them.

Shade Gardens:

A Garden in the Shade

Shade is a huge challenge for most gardeners. This garden in Hamilton, Ontario manages to be both shady and colorful: Part 1 and Part 2.

A Natural Forest Garden

Visit this peaceful garden in a forest-like setting that is a quick commute from downtown Toronto. "I have many native plants and have tried my best to integrate what I have created into the natural surroundings of a very special woodland that is at the heart of this area- many of the trees in our backyard having never been cut," says the homeowner.

Urban Gardens:

Joe's Garden

A regular feature on garden tours and open on a number of occasions each summer, Joe's garden is probably one of Brampton's best known private gardens. See Joe's garden here in Part 1 and Part 2.

A Garden Twenty Years in the Making: Part 1 and Part 2: This garden in Mississauga is one of my most "pinned" gardens which is no surprise because the planting and the front and back of the house are just beautiful.

A School Teacher's Garden

The birdbath planter in Karen's front garden is one of my most popular pins on Pinterest. Visit Karen's front and back garden in these two posts:
Part 1 and Part 2.

Cynthia's Garden

So often in a suburban garden you find yourself standing on an area of lawn while you regard the garden from a polite distance. In Cynthia's garden a flagstone path invites you inside a large corner section of the garden.

An Artist's Garden

Eleonora, an artist and interior designer, has made many changes changes to the home and garden that she inherited from her parents. Together with her husband she has added rocks and fencing, an arbor entry and a series of raised beds.  See this work in progress in this blog post.

Country Gardens:

This Walled Garden is built inside the foundations of an old barn. Clematis and other vines cover the old concrete walls, while poppies and lavender thrive in the bright sun and gravely soil.

A Visit to a Flower Farm

Technically it is not a garden, but if you love dahlias, you'll want to check out these posts on Butt's Berry and Flower Farm: Part 1 and Part 2.

A Romantic Country Garden: This country property has many striking features, but the rose filled courtyard is the garden at its most romantic and beautiful.

Beth Powell's large country garden reveals itself through a series of whimsical vignettes. Quirky and original container plantings, a canoe filled with flowerpots and floating in the pond, a seating area that seems plucked from the Tuscany countryside and a rain garden are among this gardens many unique and novel features. Visit Beth's garden in a two part series of posts: Part 1 and Part 2.

Small Gardens:

Making the Most of a Small Outdoor Space

Not every gardener has a big property to work with. Sometimes a townhouse courtyard or an apartment balcony is the only outdoor space available. In this post you will find ideas to making the best use of any outdoor space.

A Rose Garden

This is a fairly new garden, but it already has great promise. Roses and a classic focal point make for a pretty country garden.

In this post you can find photos of several small local gardens and find reference to two recent books on the subject of gardening in a small space.

Sandria brought a love of flowers to Canada with her from her native Barbados. Though she works as a nurse by day, gardening is one of her true passions. 

Private Water Gardens:

A Pretty Water GardenOversized ponds are one of the big trends in garden water features. This is one of the nicest examples I've seen.

An old swimming pool located off the back deck is artfully transformed into a large figure-eight-shaped pond. A Japanese style wooden bridge crosses the pond at its narrowest point and links the two sections.

Visit this lovely garden and pond in this blog post.

A Small Garden with a Pretty Pond: There are lots of little ideas that you can take away from this suburban garden: a nice way to edge your flowerbeds, plant combinations, a way to add privacy to a deck and a nice way to go about filling a garden urn.

Lucy Maud Montgomery Memorial Garden

Did you know that the beloved author of the Anne of Green Gables series of books spent half of her life living in Ontario and not on Prince Edward Island? Lucy Maud Montgomery lived in the small town of Norval, Ontario from 1926 to 1935.

Did you also know that Lucy Maud's husband suffered from a mental illness and that the author herself had a life long struggle with depression?

Visit the public garden built and lovingly maintained by the Norval Garden Club in memory of Lucy Maud Montgomery in this blog post.

Edwards Gardens in Toronto

Adjacent to the Toronto Botanical Garden is Edwards Gardens, a former estate garden featuring perennials, roses and an extensive rockery.

We visited Edwards Gardens one Sunday afternoon in early September. See the garden, in all its early fall splendor, in this blog post. We also made another fall visit in this earlier blog post.

At the Royal Botanical Gardens, visitors can stroll through 2,700 acres of flowers and plants, which include a bird sanctuary and woodland arboretum.

We have visited the garden many times. Visit the Rockery in May in this blog post. Visit the annual Rose Festival, in this blog post.

The Brickworks in Toronto

Is it possible to beautify and repurpose an old industrial space?  Evergreen a non-profit organization dedicated to bringing nature back into Canadian towns and cities thinks that it is. 

In 1984, the Brickwork's factory closed its doors and then in 1986, the land was expropriated by the City of Toronto and the Regional Conservation authority. The site's quarry was restored as a park and natural area. The environmental group, Evergreen focused on the site's historic buildings, revitalizing them through a process they refer to as "adaptive re-use."

Late Summer & Fall Gardens:

Late Summer at its most Beautiful Photographs of a number of local gardens taken in late summer.

The expansive flowers beds brimming with fall color leave no doubt that this small farmhouse in Eramosa township is a gardener's home. Visit the garden in this blog post.

Old School Road in Caledon, Ontario was so named, because in the days gone by, when children walked to school, there was a school built every two miles along the road. Visit a restored schoolhouse and the surrounding gardens in this fall blog post.

A Garden by Acclaimed Landscape Designer Piet Oudolf

The search for something beautiful to photograph invariably takes me to the Toronto Botanical Garden each fall. The Entry Walk Garden by renowned Dutch landscape designer Piet Oudolf is always at its best at this time of year. No matter how many times I visit, it never fails to inspire me.
