A Shade Garden in Oakville, Ontario


Over the years I have come to think that shade gardens are often amongst the most soothing and relaxing of all outdoor spaces. Shade makes them cool on a hot day. Showy drifts of flowers are beautiful, but color can overload the senses. Green feels serene in contrast. The focus of a good shade garden is on more subtle and sophisticated assets like texture, shape and contrast. You literally have to slow down to be able to appreciate them.

Today I'd like to introduce you to one such garden in Oakville, Ontario. The backyard was pretty much a blank canvas when the McAlindon's bought the property in 1984.

Cynthia McAlindon explains, "My initial vision was a modest size garden which quickly changed as I became intrigued with plants in gardens belonging to friends and family.  In some cases, I would snag seeds or cuttings and start numerous plants which I would eventually place in various areas. If I ended up with a good number of them, I would give some away to friends.  In essence, my garden is ever changing. I've even been known to rearrange the garden into December!"

"I planted three trees by the back fence which now shade the backyard.  Hostas became my passion.  I would seek out small nurseries where I would find hostas which were uncommon.  I became enamoured with miniature hostas.  There are so many colours, sizes and textures which I use to make a nature's quilt.  In the shadier areas of the garden, I planted hostas that were primarily white which attract your eyes that way."

Cynthia inherited her love of gardening from family members. 

"I was surrounded by a family of gardeners from an early age. My maternal grandmother was a prolific flower gardener for indoors and out.  My paternal grandmother, a very strict English woman, also had a flower garden that was beautiful and full of very fragrant flowers. It was my father who became enthralled with vegetable gardening." 

"My aunt had a dairy farm.  She and my uncle grew tomatoes, beans, cucs, strawberries, corn and several other crops. She had a florist shop prior to the farm and surrounded herself with flowers.  I spent years working on the farm which got me very interested in gardening and landscaping."

Ostrich Fern

As well as collecting hostas, Cynthia became a fan of other foliage plants– ferns among them, "Ferns have interested me forever. They also are my go-to for texture. I love Maidenhair, Tassel, Rabbit's foot, and Japanese painted ferns–just to name a few. Tassel ferns are my latest additions." 


Hart’s tongue, Asplenium scolopendrium has leathery, tongue-shaped bright green fronds. It likes moist, soil that is well-drained. Part-shade to full shade. Height: 30-45 cm (1-1.5 feet) Spread: 30-45 cm (1-1.5 feet) USDA Zone: 5-9.

Tassel Fern, Polystichum polyblepharum is an evergreen fern native to Japan and South Korea. It has shiny, dark green fronds and grows in a vase-shaped clump. "Tassels" appear  as the fronds emerge. This fern likes organically rich and consistently moist soil in part-shade to full shade. Plant the rhizome on an angle to prevent the crown from rotting. Height: 45-60 cm (18-24 inches) Spread: 45-60 cm (18-24 inchesUSDA Zone: 5-8.

Maidenhair Fern, Adiantum venustum

Maidenhair fern, Adiantum venustum is a Himalayan native that has wiry black stems and triangular fronds that are apple-green in color. This fern performs best in humus-rich acidic soil. Evenly moist, well-drained soil is key. Slow to establish. Part-sade to shade. Height: 20-30 cm (8-12 inches), Spread: 50-60 cm (20-24 inches). Zone: 3-8.

Forrest Grass, Hakonechloa macra 'Aureola'

Hakonechloa macra 'Aureola' forms a low mound of arching foliage striped with buttery-yellow and green. Moist soil is essential. This clump-forming grass is slow to get established but is worth the wait. Part to full shade. Height: 30-65 cm (12-25 inches), Spread: 45-60 cm (18-23 inches). USDA Zones: 5-9.

Hosta 'Guacamole' has avocado-green foliage with a darker green edge. The flowers are white. Part-shade to full shade. Height: 45-50 cm (18-20 inches), Spread: 60-70 cm (23-27 inches). USDA Zones: 2-9.

From this vantage point, the pond is partly hidden by a cluster of perennials at the foot of a tall tree.


The idea for a pond was Cynthia's but her husband can take credit for its installation:

"Twenty-five years ago I told my husband I wanted a pond and he promptly went and dug one for me.  I regularly stock it with fish and racoons regularly use it as their food source.  Damn rodents!!!"

From very bare beginnings, the garden began to take shape over a number of years.

"The back yard was flat, all grass with a Japanese maple planted tight to the house," Cynthia says."I had the tree moved close to the fence away from the house. That tree died after being attacked by a bug but several saplings grew from its keys.  Those little trees now flourish in my back yard and several have been given to friends."

"In the shade of the original tree, I planted numerous hostas and heucheras.  Immediately I bought four Austin Roses and planted them by the house so they would benefit from the sun and the warmth the bricks soaked up. They loved it. I planted herbs there also. As the years went by, I added a variety of plants such as False Indigo, Echinacea, lilies–just to name a few." 

Plants here include Heuchera, Hosta, Japanese Forest Grass (Hakonechloa) and Hellebores. 

Another key plant in the shady part of Cynthia's garden is Heuchera. 

"Heucheras are another great plant for shade gardens, "Cynthia notes."The colours that are available are outstanding.  The leaf sizes range from large to extremely small.  I am loving the purples with silver veining for more colour variety." 


Here are references to a few Heuchera that look very similar to the ones you see in Cynthia's garden:

Heuchera 'Sashay' has dark green foliage with a rust colored underside. Part to full shade. Height: 20-25 cm (8-21 inches), Spread: 20-25 cm (8-21 inches). USDA zones: 4-9.
A similar cultivar with green foliage and contrasting undersides: Heuchera 'Crimson Curls'

Heuchera 'Cherry Cola' has reddish-brown leaves and cherry-red flowers in late spring/early summer. Full sun or part-shade. Height: 40-45 cm (16-18 in), Spread: 30-40 cm (12-16 in). USDA zones: 4-9.

Alternate cultivars with dark foliage are: Heuchera 'Encore' Heuchera 'Ginger Peach', Heuchera 'Berry Marmalade' 


Heuchera 'Champagne' has peach and gold leaves with a matt finish. The flowers are light-peach on maroon colored stems. Part to full shade. Height: 25-30 cm (10-12 inches), Spread: 30-35 cm (12-14 inches). USDA zones: 4-9.
Similar cultivars: Heuchera 'Peach Flambe', Heuchera 'Vienna'

Heuchera 'Marmalade' has foliage ranging in color from umber to deep sienna. The underside of the leaves is a blend of orange and magenta. The flowers are reddish-brown. Part-shade. Height: 25-40 cm (10-16 inches), Spread: 30-45 cm (12-18 inches). USDA zones: 4-9.
Similar cultivars: Heuchera 'Amber Waves', Heuchera 'Autumn Leaves', Heuchera 'Kassandra'


Without some height, the garden could have looked a bit understated against the backdrop of the tall fence.

"One other thing I like to do is to try to get height into my garden. I have an iron urn that I change up every year.  It's in the darkest section of the back garden.  I'll fill it with smaller Hostas, Heucheras, variegated Ivy and Hellebores", Cynthia tells me.


Hosta 'Cool as a Cucumber' has long tapered leaves with a cream centre streaked and edged with green. Lavender flowers in early summer. As with many hostas, slugs can be an issue. Part-shade. Height: 60-70 cm (23-27 inches), Spread: 112-120 cm (44-47 inches). USDA Zones: 2-9.

Athyrium angustum forma rubellum 'Lady in Red' has burgundy stems and lacy green fronds. It likes moist, well-drained soil. Part-shade to full shade. Height: 60-90 cm (23-35 inches) Spread: 45-90 cm (18-35 inchesZone: 3-9.

the previous picture.

A similar combination of plants to the one you see in Cynthia's garden: Japanese Painted Fern, Athyrium niponicum 'Burgundy Lace' (left) and Coral Bells, Heuchera 'Berry Marmalade'.



Oakleaf hydrangea

Oakleaf hydrangea, Hydrangea quercifolia is a deciduous shrub that produces pyramidal panicles of white flowers in the summer.  This isn't strictly speaking a "full shade" plant. They will, however, be quite happy in lightly dappled shade that still allows in sunlight. This type of hydrangea blooms on the previous year's growth (do not prune in the spring). Water regularly to maintain evenly moist soil. Height: 4-8 ft, Spread: 8ft. USDA zones: 5-9.


So many novice gardeners find shade intimidating. I asked Cynthia for a few words of advice and encouragement:

"Shade gardening isn't that difficult. Take chances! Not every plant will survive or work into your planting scheme, but it's enjoyable to experiment."

"If you see shade gardens that intrigue you and give you pleasure, talk to the owner! Ask questions and note the names of plants!  Ask nicely for seeds and, who knows, they may share cuttings or plant divisions.  Gardeners love compliments and spending time with other gardeners. I love sharing knowledge and my plants. I have a neighbour who laughingly tells everyone 99 per cent of his garden is actually my plants." 


In among the plants, there is a wooden bird feeder and a birdbath.

"Birds are a joy to observe and to listen to. They bring me joy all year long. There are a good number of hawks in the area so it's interesting to see the birds scatter into my trees", says Cynthia. 

"Along with the birds I regularly have racoons visiting the backyard. There are several chipmunks that are so tame they will take sunflower seeds from my hands. They're too cute. Squirrels aren't my favourite but there are a good number of them running around. On occasion, opossums scamper across my back fence. Nature is wonderful."  


We weren't quite sure of the identity of this hosta. Here's a reference to one that's similar:

Hosta 'Afterglow' has heart-shaped, blue-green foliage with a chartreuse margin. The leaves of this sun tolerant hosta are moderately corrugated. The flowers are lavender. Height: 60 cm (24 inches), Spread: 121 cm (48 inches). USDA Zones: 2-9.

In a shade garden, plants have the disadvantage of low light. Amending the soil to make sure it is rich in organic matter can help compensate for this shortfall.

"For years I would attend the free mulch giveaway the town has every spring and fall. I would fill garbage bags with the mulch, pack the bags into the back of my old Windstar and drive home with a very steamy van. I wanted the best nutrients for the garden", says Cynthia. 


Sedum is a perennial that is generally regarded as requiring "full sun" but it does surprisingly well in part-shade. Here Cynthia has paired it with a Heuchera with warm peach-colored foliage.

Sedum 'Autumn Charm' has this terrific variegated foliage and salmon-colored flowers. Full sun and average garden soil. Height: 35-40 cm (14-16 inches), Spread: 45-60 cm (18-23 inches). USDA Zones: 3-9.

Heuchera 'Sweet Tea' has deeply lobed foliage that changes with the seasons. Sprays of white flowers appear in the spring. Full sun to part shade. Height: 50-68 cm (20-27 inches), Spread: 45-60 cm (18-23 inches). USDA zones: 4-9.


The bright pop of pink is a peony that is very special. "The prize of my garden is the heritage fern-leaf peony that belonged to my grandmother," Cynthia says. 


1. Hakonechloa 2. Astrantia 3. Japanese Fern, Athyrium niponicum 4. Heuchera 5. Heuchera 6. Hakonechloa 7. Oakleaf Hydrangea 8. Hellebore 9. Heuchera 10. Daylily 11. Hosta

A couple of notes on plantings: Cynthia has repeated certain key perennials (Heuchera and Hakonechloa) along the front of the garden. This repetition has a way of unifying the planting scheme into a cohesive whole. 
Most shade gardens will still have areas where the sunlight breaks through. Cynthia has taken advantage of the spots with part-shade to grow flowering perennials–a daylily, a tree peony, an Oakleaf hydrangea and an Astrantia are a few examples. 


"Using texture over color results in a garden that is extremely soothing and serene," Cynthia muses. "Friends regularly will comment on the calming effect my garden has and that is extremely pleasing to me."

Cynthia has every right to be proud of her garden. It's beautiful in a quiet and sophisticated way. Without the high drama of a lot of flowers, nothing demands your attention. I think that is why green feels so restful–it is every bit as relaxing as soft music.

Beginner Series: Overcoming that Dreaded Fear of Failure– 8 strategies for Gardening Success

Tulip

I have been gardening for longer than I care to admit.

The problem with being a garden writer with lots of experience is you forget what it's like to be gardening for the first time. What is it like to look at your yard and not even know where to begin?

This spring, I had a little reminder of what it must be like to be a novice gardener. I have a brand new flowerbed with absolutely nothing in it except a few daffodils that I managed to put in last fall. It's intimidating to look at that big, blank canvas.

With this new project, I face many of the same challenges most new gardeners would encounter. It won't be like one of those television makeovers shows with a pathetic "before" and a dramatic "after" transformation. Nobody is going to pull up to my house with truckloads of free plants and a full work crew. Like most real-life gardeners, I have a budget and limited resources. Rest assured, I'll scrounging around for free stuff, buying small plants and growing lots of stuff from seed.

Never allow the fear of failure to become a motivator to do nothing. Even though I have been gardening for quite a while, not everything will be perfect the first time. There's bound to be a few plants that will be placed in the wrong spot or ones that I plant too close together. There will be times when I ask myself– what was I thinking?

As with so many things, you experiment. Some things work and others don't. Take pleasure in what's good and fix your mistakes. Persistence is your most important ally. Slowly the garden will come together.

Here are 8 simple strategies to help get you started:


Violets

1. Sit in a comfortable outdoor chair and do absolutely nothing.


I know this gardening advice is a bit unorthodox, but I think it pays to spend time just enjoying the outdoors. Sit and read a book, watch the birds, listen to the wind in the trees.

Before you do anything, decide how you want to use your outdoor space –whether it is for relaxing, entertaining or just watching the kids play. Then design your garden to work for you.


2. Start Small


You'd never dream of decorating every room in your house all at the same time. It would be overwhelming, not to mention expensive. You're much more likely to tackle it one room at a time.

Take the same approach in the garden. Don't try to conquer the whole yard at once. Start small with a few containers. Don't locate them miles from a water source or at the back of your property. When I put cut flowers in the house, I place them on a hall table or in a location I pass frequently.
Then branch out into a small flowerbed and slowly build your confidence.

• Mallow, Malva sylvestris
• Delphinium
• Maltese Cross, Lychnis chalcedonica
• Butterfly Weed (both Asclepias incarnata and Asclepias tuberosa)

Forget-me-nots

3. Be realistic about the time you have to devote to your garden.


I speak from the experience of being too ambitious, but I've learned from my mistakes. When I added the new flowerbed, I knew enough to grass over another. I'd rather have a small garden that looks good than a big garden that's a mess.

4. Don't delay! Get those plants into the ground.


Plants in nursery pots dry out sooo quickly! Even after you revive them with water, they become stressed and soon enough they'll become pot bound. It's better to get the placement wrong and move plants around in the fall than it is to wait.

As Elizabeth Gilbert says in Big Magic, her new book on creativity," Done is better than perfect."

Trout Lily, Erythronium

5. Water well until your plants are established.


Getting your plants into the ground quickly will help with keeping them hydrated, but even so, plants right out of a nursery pot have a small root system so they will need supplemental water until they are settled in.
When you're busy it's hard to find the time to drag out the hose and water your garden. If you can afford it, consider adding a drip irrigation system.
And if that is out of the question, to ease the work locate container plantings that will dry out quickly close to a water source.

Drought-tolerant perennials–Top row left to right: Yarrow, Lavender, Sedum. 
Bottom row left to right: Coreopsis, Dianthus, Catmint

• Milkweed, Asclepias
• Lavender, Lavandula
• Sedum
• Dianthus
• Coneflower, Echinacea
• Tickseed, Coreopsis
• Catmint, Nepeta 
• Oriental Poppy, Papaver orientale
• Brown-eyed Susan, Rudbeckia
• Rose Campion, Lychnis coronaria

Hellebore

6. Carefully consider light conditions.


When I first planned out my new flowerbed I envisioned a prairie-style planting with lots of ornamental grasses. The problem is ornamental grasses need 6-8 hrs of full sun a day. There are no overhead trees casting a shadow in this area of the garden, so I thought I was working with full sun.

When I really started to pay attention to the light levels, I discovered that the two trees on the other side of our property block the sun as it moves across the horizon. Those 6-8 hours of bright light had a couple of big breaks when the sun passed behind the trees. Time for a rethink!

If you're planning a flowerbed, take a day from dawn to dusk and clock just how much sun that area really receives. Then choose plants to suit.

7. It all starts with the soil.


If your soil is poor or so clay you could make pottery, amend it by digging in some organic matter (compost or well-rotted manure).
A raised bed is a great way to get around the problem of poor soil (the book pictured above has many DIY raised bed ideas). Once the framework is constructed, you can fill the bed with the best topsoil.
And of course, you can always opt to work with what you've got. If your soil is clay or low in nutrients, there are still some plants that will do well.

• Tickseed, Coreopsis
• Russian Sage, Perovskia
• Blue Star, Amsonia


Perennials for clay soil left to right: Variegated Sunflower or Heliopsis, Baptisia, Russian Sage


Primrose

8. Start each day in the garden with a stroll.


While there is a practical purpose to this– I make mental notes on what needs attention and the chores that are the most urgent– a walk around the garden before I do any work is by far my most favourite time of the day. It's on that stroll I see the results of all my hard work. There are often surprises- an unusual bird sighting or a butterfly or hummingbird flitting among the flowers. And there are always delights such as a flower that has come magnificently into bloom.

In gardening, I find that even my smallest successes outshine my most miserable failures.
