One of the perks of being a garden writer is I sometimes get to trial new plants and seeds a year before they appear in retail nurseries, garden centres, or catalogues. I may also spot a striking specimen in other trial gardens a year or two before they’re released, or watch someone in the plant world tease new varieties in a talk. And at some point in any given year, my inbox starts to receive sneak peeks at new plant introductions. By the time the growing season rolls around, I’m usually pretty prepared to make recommendations—and seek out my favourites for my pots and plots.

Speaking of new plant introductions, I got a behind-the-scenes look at how that whole business works after attending the California Spring Trials with the National Garden Bureau a couple of years ago. That trip gave me an extra sense of appreciation for the work that goes into plant breeding, and the pride that comes from releasing interesting new annuals and perennials to the world.

And so, this will be the page where I discuss the eye-catching new plants that cross my radar each year. Check back in from time to time, as I’m sure I’ll be adding a new plant here and there if I discover something special.

New plants for 2020

Superbells Blackcurrant Punch and Double Blue Calibrachoa
Calibrachoas are container regulars in my garden, probably because every year yields an interesting new collection of varieties. They make great spillers in both hanging baskets and containers and bloom all season long (without having to deadhead). Often a calibrachoa will determine the colour combination of my arrangements. There were two superstars in my garden this year: Superbells Blackcurrant Punch and Superbells Double Blue, which Proven Winners sent to me to trial.

Blackcurrant Punch is a gorgeous fuschia hue with a black and yellow centre. The black part looks like it was painted on by a leaky felt-tipped pen.

Superbells Blackcurrant Punch is gorgeous and the whole plant absolutely popped planted beside a lime green coleus.

Double Blue was planted in my main urn along with alyssum and a selection of herbs, like trailing rosemary and parsley. It paired nicely with a deep purple salvia, and the purple and mauve Superbena Sparkling Amethyst Improved Verbena.

Superbells Double Blue is more of a purple hue with ruffled petals.

Wave Carmine Velour Spreading Petunia
I grew this lovely petunia from seed in 2019 and it bloomed through the fall. The colour is a vibrant red, but it’s the delicate centre pattern that is really stunning when you look at it closely. Part of the Wave family, it’s a 2019 All-America Selections Winner.

My Wave Carmine Velour Spreading Petunias were grown in a container, but trial judges said they worked well as a groundcover, too.

Marigold dropshot
I’m fortunate to live near William Dam Seeds, so it’s fun to get a sneak peek of new varieties in their trial gardens. In August, I had the chance to get a tour with flower and herb seed manager Connie Dam. After looking at rows of ornamentals abuzz with pollinators, we headed over to an herb garden where she pointed out a plant and encouraged tasting it. The plant had a licorice flavour that can be used as a tarragon substitute. It’s called Marigold Dropshot, and while you might expect it has flowers, it is all about the feathery foliage.

Marigold Dropshot is an interesting new plant because it is both edible and ornamental

In the trial garden I visited, Marigold Dropshot had a nice round habit, which would provide a really nice backdrop to showcase a showier ornamental bloom of a similar height.

Coleus Main Street Beale Street
I usually pick up at least one variety of coleus on my yearly garden centre travels. I’m excited to keep an eye out for the rich red hue and scalloped edges of this gorgeous variety. Main Street Beale Street is a 2020 AAS Ornamental Winner, the first-ever coleus to win the honour. Apparently the foliage doesn’t fade over the summer and it’s supposed to thrive in full sun and full shade.

UpTown Frosted Strawberry Zinnia
Zinnias are another garden staple that are super-easy to grow from seed. In 2019 I grew two red varieties, so I’m feeling this pink ombré variety that is heat tolerant and has excellent disease resistance. Zinnias are pollinator magnets—bees and butterflies love them, and I’ve even seen hummingbirds on the zinnias in my garden. Once they take off, they usually bloom right through the fall. Zinnias also make great cut flowers.

Bright Lights Berry Rose Osteospermum
Speaking of pink, I really loved the blooms on Bright Lights Berry Rose. For some reason, I’ve never grown Osteospermums before. This variety featured a gradient from white to deep pink, with flecks of orange in the centre. They really popped against the deep blue of my Muskoka chairs and outdoor carpet. These heat-tolerant stunners also bloomed for me more than once, the last blooms fading at the end of the fall.

Osteospermum Bright Lights Berry Rose is a new favourite of mine and a hot new plant for 2020 gardens

Also called African Daisies, osteospermums come in a rainbow of hues. Bright Lights Berry Rose is a new favourite of mine.

Sedum takesimense ATLANTIS
The hardiness and versatility of sedums make them perfect groundcover candidates for my dry, sunny, exposed front garden. The green and yellow leaves of this variety make it a showstopper. In the fall, their edges apparently become tinged with pink. That’s probably why Atlantis was named the Plant of the Year at the 2019 RHS Chelsea Flower Show. This perennial also happens to be salt tolerant and will attract pollinators. It is hardy down to USDA 4a.

Lavandula Bandera Deep Purple
Generally lavandula comes in light shades of mauve or pink, so this deep purple hue really stands out. I can see it looking great in a light-coloured container, paired with lime green foliage. It is long-flowering and self-cleaning (no deadheading required!) and likes the sunshine.

Lavandula Bandera Deep Purple can look interesting on its own in a pot.

I’m a sucker for standout foliage, so I have a few heucheras throughout my gardens. I love using them in container arrangements and then they’ll eventually make their way into the garden. This one is hardy all the way down to zone 3 and heat tolerant. The leaves start out a vibrant light green with subdued red veins in spring, but evolve to a more orange-chartreuse with a deeper pattern over the summer months. The flowers look quite stunning, too.

Heuchera NORTHERN EXPOSURE™ Sienna features stunning foliage, making it a must-have new plant for 2020.

New plants for 2019

Echinacea KISMET Raspberry
I like how echinacea plants bloom as ready-made bouquets in the garden. They grow well in my dry front garden, add interesting bursts of colour, and the bees love them. The flowers look interesting in all their stages of growth, even as they die off. I deadhead throughout the season, but those last blooms of fall are left in the garden over the winter, so the birds can eat the seed heads. I have planted a few varieties of this perennial over the years, including Cheyenne Spirit. Echinacea KISMET Raspberry, from TERRA NOVA Nurseries, blooms in full sun from early summer until first frost. Apparently, this variety grows well in a container, too.
Zone: USDA 4-9

Panther Ninebark (Physocarpus opulifolius)

I’ve become a real fan of ninebarks, especially when they bloom. The delicately hued flowers against the deep dark foliage is quite a stunning combo. And it provides a great backdrop for other flowers and foliage, too. This new variety from Bloomin’ Easy has sumptuous, black-tinged foliage, loves full sun and has a stronger mildew resistance. This shrub grows between four and five feet tall, and about two to three feet wide.
Zone: USDA 3

The sleek foliage of this Panther ninebark is the reason it landed on our "Hot new plants for 2019" list.

Nasturtium Baby Rose

I sow nasturtium seeds every year among the edibles in my raised beds. Nasturtiums are great triple-duty plants: You can eat the flower petals and leaves; the pollinators love them; and they can be planted as a trap crop for aphids (if you don’t mind sacrificing a plant here and there). I guess a fourth bonus is that no matter which variety you choose, nasturtiums have very unique blooms. A few years ago I was delighted to discover Climbing Phoenix, with its serrated petals, rather than the more scalloped ones you’ll find on most other varieties. Baby Rose, which appears to be a similar rosy hue to the echinacea (hey, I have a type!), is a 2019 AAS winner. This compact plant is a great choice for small spaces and containers. I’m adding it to my seed order list!

Because of its compact nature, Nasturtium Baby Rose is perfect for small spaces. It also made our "hot new plants for 2019" list!

Chinook Sunrise rose

I love that plant breeders have been working on growing hardy roses for modern gardens. Vineland Research & Innovation Centre in Lincoln, Ontario launched their 49th Parallel Collection with Canadian Shield a couple of years ago and this year, they are releasing Chinook Sunrise. I got to see the plants in person at Canada Blooms in March 2019 and the blooms are really pretty. This hardy plant is black spot tolerant and hardy down to zone 3 (Canada).

Butterfly Coreopsis Incredible

I love when a seed packet yields more than one colour of flower. That’s why I enjoyed the Queeny Lime Orange Zinnias I grew in 2018—no flower looked the same. This new introduction from Renee’s Garden, Butterfly Coreopsis Incredible, features a mix of flowers in soft cream, maroon, yellow, and shades of red. This is a pollinator-friendly plant that is deer resistant and that can withstand hot, dry spells.

Superbells Doublette Love Swept Double Calibrachoa

Calibrachoas have become container staples on my property. Each season, I choose at least one variety for a pot or hanging basket. These annuals don’t get leggy, they’re heat tolerant and self-cleaning, and they bloom right through the fall. It looks like someone took a paintbrush and carefully painted white around the edges of this new hot pink variety from Proven Winners. I love details like this. These plants are great “spillers” in containers and will also cascade over hanging baskets—and they attract hummingbirds!

Look closely at the detail on the petals of this calibrachoa hybrid, Superbells Doublette Love Swept, from Proven Winners, a hot new plant for 2019

Dahlia Belle of Barmera

I would be remiss if I didn’t include a plant belonging to one of the National Garden Bureau’s “Year Of” series. 2019 is The Year of the Dahlia, so I included this showy new variety from Longfield Gardens. And since my inbox has been flooded with emails showcasing plants that are coral, the new Pantone colour of the year, Belle of Barmera checks that box, too. Plant your tubers in sun to partial sun/shade and wait for the frilly, ruffled blooms.

2019 is the Year of the Dahlia and coral is the Pantone colour of the year, so Dahlia Belle of Barmera checks both boxes and would make a stunning addition to your ornamental garden to boot!

Not new, but still gorgeous: New plants from past years

Here are 5 new ornamentals to plant in 2017

Canadian Shield™ rose
This rose got a lot of buzz at Canada Blooms this past March. It is the first rose from the 49th Parallel Collection to be launched from Canada’s National Hardy Rose Program, part of the Ontario-based Vineland Research & Innovation Centre. This rose is hardy to zone 3 and was bred to be low-maintenance—it is self-cleaning and disease resistant. It will be available at various nurseries across Canada (call ahead as some places have already sold out), as well as at President’s Choice Lawn & Garden Centres.

Above and Beyond rose
Since I don’t think Canadian Shield is available in the United States, let’s also talk about this zone 3 to 7 Above and Beyond climbing rose from First Editions. This eye-catching climbing rose is resistant to fungal disease and will apparently re-bloom sporadically throughout the summer.

Vista Bubble Gum, Vista Fuchsia, and Vista Silverberry Supertunias
I’ve grown Supertunias from Proven Winners in various containers for the last couple of years and they LOVE my sunny front yard. Last year I planted a container with the Vista series varieties listed above and they were so prolific, it was hard to get the whole container in the picture! I grew lemongrass in the centre for height (instead of a dracaena) because it’s a great Garden BFF—edible AND ornamental!

Date Night™ Crimson Kisses Weigela
Because this year marks Canada’s 150th birthday, there is much talk about planting red and white in the garden to celebrate. I’m excited to plant this weigela so I can add some red to the landscape. In Canada it is hardy to down to zone 4 and USDA hardy in zones 4 to 9. Apparently it remains nice and compact and will re-bloom throughout the season. In Canada, it’s available via Van Belle Nursery under the Bloomin’ Easy line and in the U.S., Monrovia carries it. I have one that I’m keeping in a sunny window, waiting to go into the garden.

Phlox Popstars Rose with Eye
I fell in love with these blooms that look like fireworks at the Floranova booth at the California Spring Trials. They’re said to bloom from June through August and they are very heat tolerant. And, as the National Garden Bureau pointed out, these aren’t your Grandma’s flowers! Keep an eye out for this flashy plant at your local garden centre or sow them from seed.
