Contrasting Colours in Gardens and Containers

step out of your comfort zone

Contrasting colours rather than complementary ones make a bigger impact in your garden. Most people tend to opt for complementing colors when choosing plants. I always tell my clients remember, you are not wearing the plants, they do not have to match!

Choose colours that are opposite (not next to) each other on the colour wheel (as pictured above) to create some drama.

Use Colour Contrasts in Containers Too

I love using coleus in containers for the wide range of contrasting colour in their foliage. Straight from the nursery, choose from the many options in contrasting colour combinations within the same plant! The chartreuse green of creeping jenny or sweet potato vines make the red tones of the coleus pop in your creations:

For full sun containers, I tend to go for purple, pink, red, blue and yellow for the “fillers” and “spillers.” Their bright colours look so summery and vivid against the various shades of green which are perfect backdrops for “thrillers” and additional “spillers.”

Choose Perennials with Contrasting Flower Colours but the Same Bloom Time

When choosing perennials for your garden beds, instead of picking matching colours, try selecting contrasting colours in plants that bloom at the same time. For example, this yellow ligularis in front of a purple clematis creates a much more eye-catching scenario than two yellow or two purple plantings.

Another great example in my yard is my collection of daylilies I have in a raised bed at the side of my house. From dark wine-red to pale peach, they are contrasting yet compliment each other beautifully!

Foliage with Contrasting Colours

Another trick to make individual plants stand out is to place contrasting foliage colours next to or in front of each other. An example here is the leaves of a purple smoke tree (that just had a haircut so will soon be much taller) behind (right now it looks like it’s inside) the bright green leaves of a hydrangea.

Try some new contrasting combinations in your garden to create some drama. Be sure to send me pictures of your combinations.

Remember, forget the matchy-matchy look, you are not wearing the plants!

Thrillers, Fillers, and Spillers

When designing summer, autumn, or winter containers be sure to follow the thrillers, fillers, and spillers rule for maximum effect. The “thriller” is the center, tallest plant. The spillers go around the perimeter of the pot; choose ones that sprawl “spill” over the edges. The fillers go in between the thrillers and the spillers to fill in the bare spots.

Annuals or Perennials?

Most people choose annuals over perennials for their summer containers. That’s because annuals bloom all summer until frost kills them off. Perennials, on the other hand, bloom for two weeks on average, if you’re lucky. You can use a combination of both for your thrillers, fillers, and spillers. For example, perennial ornamental grasses make an awesome, inexpensive (dig a clump up from your garden) “thriller” (center) for containers.

Sun or Shade?

When designing your container, be sure to take its intended location into consideration. Some plants (both annuals and perennials) like full sun, others full shade, with others somewhere in between. Don’t try to combine these different requirements in the same container. If you do, some will thrive, and others will fizzle.

You can probably tell from these pictures that coleus and hibiscus are my favourite annuals for shade and sun containers respectively….

Fertilizer

Containers of annuals can be fertilized weekly right up until frost. This practice will keep the annuals looking cheerful as long as possible. Perennials need less fertilizer, especially those in garden beds when monthly is ideal up until August (in zone 4/5).

Deadheading and Pinching

Deadheading, or removing spent blossoms, helps to keep your containers looking nice all season. For annuals and perennials with flowers on stalks, remove the stalk right back to the first set of leaves after the flower has passed its peak. This practice often encourages repeat blooming. Others just need the faded flowers picked off.

Pinching the center of annuals and perennials encourages them to get bushier instead of leggy.

Frost Warnings

While annuals will be affected by frost, most perennials will not. Some annuals tolerate a light frost, others not so much. Of course, the first frost date varies across the globe, sometimes year to year within the same area.

In other words, frost is unpredictable.

Perennials can overwinter in your containers if you choose plants two zones hardier than what is normally hardy in your area. Otherwise, you can stick them in the ground to overwinter, to use again the following spring.

You can extend the season on both ends by heeding frost warnings in your weather forecast. In the spring I tend to start my containers early to ensure I get the annuals I want. If a frost warning is issued, I move the containers into my garage, off the (cold) cement floor, for the night in question. The same technique can be used in the fall when a sporadic early frost is in the forecast.

Once frost has set in for several days, you are fighting a lost cause. It’s then time to switch your concentration to fall or winter containers. Use the same thrillers, fillers, and spillers technique to create unique designs…

Wedding Planning with Gardens4U

Recently I told you of a project Gardens4U has been working on all summer. To recap, a client asked me to spruce up the gardens at his parents farm for his daughter’s wedding. Although Gardens4U has not done extensive wedding planning, this project was so much fun.

Where to Start the Wedding Planning

After walking around the extensive property with the client last April, the wedding planning began. I started by working on multiple neglected garden beds. Containers were planted as soon as the last frost date arrived in May, well in advance of the wedding date to give the annuals time to settle in.

My original commitment was one day a week, including through the scorching heat we experienced this summer. Of course, my visits to “the farm” increased in recent weeks as the wedding date drew closer.

Most of the time I remembered to take before and after pictures of the gardens and planters. I so wanted to snap a few last-minute pictures the morning of the wedding but did not want to intrude on the hustle and bustle going on. I will have to wait patiently for the photos I know my clients will share.

Garden Beds

The beds I worked on are referred to here according to their location on the property or their function during the wedding. Pictures are posted in chronological order.

House Bed, 3 Sections:

I cannot take credit for the gorgeous, flagstone sidewalk or lush lawn enhancing these beds at the front of the home. Due to the large expanse of lawn and the poor condition it was in, hydroseed (a sprayed-on product) was used with awesome results. A beautiful lawn does wonders for increasing the beauty of gardens…

Ceremony Site:

There is no “before” picture for this bed as there wasn’t a garden there, just the edge of the yard overgrown with trees, scrub brush, and a few transplanted hostas.

Shady Sitting Area:

My client had a vision for this bed, I really just followed his instructions. And chose and planted the appropriate perennials for a shady spot. We then used some of the containers to add some colour to the area…

The Mint Bed That Became a Dahlia Bed:

For the resident chef, I moved the mint into a new herb garden. At least I attempted to move it. Mint can be very invasive, there are still shoots sprouting in that bed.

Sunny Beds:

These two beds were the bride’s Omi’s (grandma) flower gardens, with the one on the right home to her beautiful peonies. Unfortunately, they were overgrown with no distinct shape and neglected since her passing several years ago.

Sunflower Bed:

This sunflower bed was supposed to be spectacular, at least that’s the vision I had. Tall, majestic, golden yellow sunflower blooms against the backdrop of the rustic family barn bordered by the bride’s Omi’s (grandma) long-established daylilies. We tried to transplant many of the daylilies into some semblance of order, but thanks to their poor performance through the drought conditions this summer I had to cut them right back. They did revive, but not as fast as I hoped they would.

Rock Garden:

I don’t have much experience with rock gardens but I enjoyed choosing creeping plants and tiny succulents to tuck into the crevices. Unfortunately (for the wedding guests) not many of these types of plants are fall bloomers. Next spring and summer it will look gorgeous!

Rodent and Insect Damage Deter Wedding Planning

My major challenge during this project was the battle I had keeping the sunflowers intact in their designated bed against the barn wall.

I planted close to thirty sunflowers, most grown from seed on my back veranda. Unfortunately, the squirrels snapped off their growing stalks faster than I could plant them. I actually witnessed a squirrel hanging on the barn wall, mid-pounce, as he/she aimed for the flower head of one of the tallest sunflowers.

So frustrating and disappointing!

The other challenge was keeping the dahlia blossoms from becoming a snack bar. Earwigs or whatever other insect devoured them shortly after they appeared and before they could mature. I ended up bringing a pot of dahlias from my back deck to fill in the bare spots.

Containers: Thrillers, Fillers, and Spillers

We used lots of planters around the property to add colour and drama. Some came from the client’s home that I had created earlier in the season. The rest I brought over from my own home collection.

Silver Lace Vine

I had planned to drape strands of silver lace vine (from my garden) in the trees to look like the beautiful Spanish moss so prevalent in the south. The wedding planner, who is also a florist, intercepted me though as I carried trays of it down the driveway. She asked for the silver lace to adorn the dining table and archway at the ceremony site. How could I refuse?

Conclusions:

Well, the big day arrived and thankfully the sun was (albeit off and on) shining! We were all nervous as it had been raining, torrentially at times, for the previous two days.

The problem with creating these gardens in one season is that most plants take a while to mature in their new homes. Unless of course, you spend a fortune and choose fully mature plantings. Like most gardens I plan and create, these garden beds look great this season but will look spectacular next summer and for years to come.

A few years ago I created bouquets and containers for my son’s wedding. Then a few years later I created table arrangements for a friend’s son’s wedding. I have enjoyed these wedding projects so much that I am considering adding wedding (or other events) planning to my Gardens4u list of services!
