The Queen of the Classic Garden Border

By Ava Green

Tall, stately, and undeniably dramatic, the Delphinium or Larkspur is one of those perennial plants that stops people in their tracks. When given the right conditions, its towering floral spikes are magnificent. For gardeners who love a classic English border, nothing else compares. Yes, Delphiniums have lots of preferences, but tend to them, and they will reward you with a floral display that makes every bit of effort worthwhile. 

Choosing Your Delphiniums

With a wide number of varieties to choose from, there’s one that’s sure to fit every garden. Heights range from a modest 36 inches to an impressive 72 inches tall (Yes, 6 feet!), with a spread of 24 to 36 inches depending on the variety. So whether you have a compact border or a large sweeping bed, there’s a Delphinium to suit your space.

Their colour palette is equally diverse: rich blues and purples, soft pinks, crisp whites, and beautiful bicolours. Few flowers offer such a wide range. 

Planting

While Delphiniums prefer abundant moisture, be sure to plant the crown of the plant (where the stems meet the root ball) at soil level to avoid crown rot. Planting them too deeply is the most common way to lose these plants.

Spring and Fall are the ideal times to plant, giving roots a chance to establish themselves in cooler, more forgiving conditions. That said, a cool, overcast summer day works well too, just avoid planting during hot or humid spells. Spacing will depend on the variety you choose, so check the tag and give each plant the room it needs to breathe.  

Growing

Delphiniums are what gardeners affectionately call “Goldilocks plants”, they like things just right. Full sun, protection from strong winds, and fertile, humus-rich soil with excellent drainage are keys to success. They also love manure mixed into the soil to enrich their growing conditions. 

Their height is both their greatest asset and vulnerability. Because Delphinium flower stalks have hollow centres, they break easily if they’re exposed to the wind. Planting them in a sheltered spot is genuinely important. Once plants reach about 12 inches tall, stake each flower spike individually, or place a tomato cage around a clump early in the season before it’s needed. It’s much easier to stake proactively than to rescue a snapped stem after the fact.

Delphiniums are hungry plants and will perform best when fed generously. A dose of fertilizer, compost, or well-rotted manure in both spring and summer keeps them healthy and productive throughout the season.

Finally, don’t overlook dividing. Each spring, simply dig up the plant and cut the root ball in half. Now you have two plants for your border, or one to keep and one to share!

The Show

All that care pays off in late spring and early summer, when Delphiniums put on one of the most spectacular displays in the garden. Tall, densely packed spikes covered in richly coloured blooms rise above the border like beacons. Bold, beautiful, and completely unforgettable. 

Once the first flush of flowers begins to fade, and before the blooms turn to seed pods, cut the spent spikes back to just above the foliage. This encourages the plant to produce a second, smaller flush of blooms later in the season and extends the show! As the old foliage fades, trim it away to allow the fresh new growth to replace it.

Inspiration

There are plants you fit into a garden, and then there are plants you plan a garden around. Delphiniums belong firmly in the second category. Their height, colour, and presence make them one of the most inspiring and rewarding perennials a gardener can grow.

Stop by Eising Garden Centre to see what Delphinium varieties we have available this season. Our team is always happy to help you find the right fit for your garden and set you up for success. 

If flowers are the divas of the garden, foliage is the harmonious backup group that makes the whole performance shine. Colour, texture, and form don’t just come from blooms—there’s a world of interesting leaves that not only set the stage but often steal the show. Flowers may be the stars, but foliage is the picture frame, the atmosphere, and often the soul of a beautiful garden.

Start with a Standout

When choosing plants—whether for a garden bed or a container—don’t just focus on flowers. Especially in shady spots, standout foliage can create all the visual impact you need. Look for leaves that draw your eye, like the delicate structure of a cutleaf Japanese maple or the bold colour variations of Heuchera (Coral Bells), which range from deep burgundy to vibrant chartreuse.

Your standout feature doesn’t have to be a plant—it could be a sculptural shrub, an ornamental tree, or even a favourite birdbath. Try placing that birdbath atop a lush carpet of Irish moss, or line a path with the spotted leaves of Pulmonaria, silvery Artemisia, or graceful ferns. Light up a shady corner with glossy Bergenia or classic Hostas, which offer endless variety in shape, texture, and hues from bright green to cool blue-ish tones.

Build the Framework

Once you’ve chosen your focal foliage, you can build your planting scheme around it in creative ways. Think of it like building a quilt—each plant contributes a piece to the overall picture.

• Create a patchwork of leaf shapes: Group together plants with small, intricate foliage for a richly textured look.

Mossy Saxifrage 'Cloth of Gold,' Sagina Subulata 'Irish Moss,' and Bellflower Campanula Carpatica 'Pearl Deep Blue'

• Echo colour tones: Pair burgundy Heuchera with other plants in similar shades, like dark-toned Euphorbia, for a cohesive palette.

Foamy Bells 'Catching Fire,' and 'Onyx'

• Choose a colour theme: Work with warm hues like gold, rust, and copper.

Japanese Maple 'Tamukeyama,' 'Magnolia x Soulangeana,' and Lobelia Speciosa 'Starship Scarlet'

• Mix textures, repeat colours: Choose different textures but repeat colour combinations like white and green.

Pulmonaria 'Pink-a-Blue' and Artemesia 'Silver Mound'

Top it Off

Once your foliage framework is in place, add a statement piece to elevate it all - that favourite birdbath, a piece of artwork, an ornamental tree or shrub, or an unexpectedly showy flower. The layered, leafy backdrop with make your feature stand out even more.

If you bought a live tree for Christmas, maybe from your friends at Eising, and you’re wondering what to do with it after the holidays, we have 7 ways to recycle or upcycle it. The needles and tinsel may be falling off, and you’re probably ready to give it the “Heave Ho!”, but wait! Check out these ideas first:  

1. Create a wildlife shelter and winter interest

Let's put our Christmas trees to work in our gardens! If you have a bare spot in the yard, moving your Christmas tree outside is a great way to instantly “spruce” it up! You can leave the tree right in the stand, or prop it up on a fence, maybe even add a string of outdoor lights to enjoy on the dark winter nights coming our way. Doing this will give you something pretty to look at for sure, but more importantly, it provides additional shelter for birds and wildlife.

2. Enhance your garden soil

A live Christmas tree is 100% biodegradable. By turning it into mulch or compost it will break down and return stored nutrients back to the soil. Now that’s a win-win! And it’s easier than you may think. If you don’t have a shredder, branches can be chopped up by using good ‘ol pruning shears. Needles are full of nutrients and will also help soil from becoming dense and compacted. Using wood chips, chopped branches, and needles as a mulch is also a great way to help your garden trees stay moist and healthy during the winter. If you’re adding the needles and branches to your compost pile, be sure to add some water and mix it well with the rest of the compost. Another option is to add the chopped branches and needles to a garden path.

3. Protect your plants

There’s still a lot of winter weather ahead of us, and your tree can help protect perennials that are marginally hardy. Simply cut long branches from your Christmas tree using loppers, pruners, or a saw, and lay them over perennial plants to add insulation. The boughs will protect your plants from winter freezes and spring thaws, which could be the difference between losing a plant and seeing it grow again next year.

4. Keep the fresh pine scent

Are the needles on your tree still green? Use gloves or scissors to strip them from the tree, then store the needles in paper bags to use as room fresheners. The needles can retain their scent for months to come.

5. Support for Spring

Branches make lovely natural supports for any plants that need a little propping up - like peonies for example. Once the branches are trimmed off, the trunk can be used to support vines like Morning Glories or pole beans, or by laying it on it’s side as an edge for a garden.

6. Get creative

Crafts like ornaments and coasters are a great way to upcycle a tree trunk. Be sure to let the tree completely dry first or the wood will split when you cut it into 6 to 10 millimeter thick rounds. Then get creative by painting or varnishing and drilling holes in them if you’re making ornaments. They’re attractive, practical, and make great gifts.

7. Donate it, or take it to a recycling centre

If you have no need for recycling your living tree for home use, then look for a local program to donate your tree to. For over a decade, the Royal Botanical Gardens in Hamilton has used donated Christmas trees for various stream restoration projects. More information about their programs can be found on the RBG site. Or, skip the drive to Hamilton and check for your county recycling program. In Norfolk County for example, you must drop your tree off.

What’s not on our list? Burning your tree. You definitely do not want to burn it in your fireplace as it’s creosote content makes for a sticky, sooty fireplace. It’s not recommend that you burn it outdoors either. Coniferous needles contain nitrogen and substances called terpenes which are very toxic when burned, making the smoke unsafe for anyone around your fire pit to breathe. It’s much better to do any of the things listed above, or, if you have your own wooded area or pond, you can also put your tree in either of those places to enhance the natural habitat for woodland animals or fish.
