5 Stunning Dahlias You Should Grow in Your Garden
Where do we begin !
Is your nosy neighbour peeking their snooty nose over the fence? Do you feel like your garden is missing that “wow” factor? Are you searching for a beautiful statement piece that will leave that neighbour quietly simmering with envy at how stunning your flowers look?
Or maybe you’re simply looking for something beautiful to admire while sipping your morning coffee.
Either way, don’t worry. Dahlias are the answer!
If you're a gardener, chances are you've come across dahlias before. They’re often sold as seed packets or tubers in garden centres, and if you're in the UK, many county agricultural shows feature spectacular dahlia sections with breath taking exhibition displays.
Stepping into the world of dahlias can feel a little overwhelming. A quick google search suggests there are around 40,000–50,000 varieties. I can't promise that number is exact, but once you start exploring, it certainly feels believable!
Of course, you could simply grab a packet of seeds and be on your way. But dahlias offer something more — a chance to express your personality through your garden. There truly is a dahlia for everyone. They're wonderfully versatile too: grow them outside, in a greenhouse, as cut flowers, borders, or even in pots.
But if you're dreaming of a beautiful cut-flower bed or a peaceful garden bursting with colour, there’s no need to look through every variety in existence.
Here are five dahlias that deserve a place in your garden.
Kilburn Glow Dahlia, Water Lilly Variety
It’s a favourite among gardeners who want something eye-catching in borders or a reliable variety for cut-flower arrangements. Personally, my favourite. Magenta-rose or bright pink petals that fade to yellow at the base, it just screams pink diva.
Kilburn Glow produces flowers from mid-summer through to autumn, usually from July until the first frost. If you’re growing dahlias in a greenhouse or polytunnel, you can often extend the flowering season even further. Regular deadheading or cutting blooms will encourage the plant to keep producing more flowers — making it a perfect variety if you love filling vases around the house.
From personal experience, Kilburn Glow actually thrives on a little neglect. Too much water can cause the tubers to rot, so heavy watering isn’t necessary. In most cases, watering every other day during warm weather is more than enough, meaning you can easily leave for the weekend without coming back to a sad, wilted plant.
Just make sure it has full sun, moist but well-drained soil, and around 45–60 cm of spacing. Proper spacing is important as it improves airflow between plants, helping to prevent fungal problems and keeping your dahlias healthy throughout the season.
Gurtla Twilight Dahlia, Pompon Variety
A truly whimsical garden feature, I have never quite seen a flower like this. The delicate purple edging on each petal is not only stunning but also unique to every single bloom, meaning you’ll rarely find two flowers that look exactly the same. The perfectly rounded, ball-shaped heads, usually around 5 cm in size, almost resemble little lollipops or colourful sweets dotted around the plant. It’s playful, charming, and wonderfully eye-catching.
With its soft colours and neat pompon shape, Gurtla Twilight gives serious cottage-core vibes, making it a beautiful addition to borders, cutting gardens, or anywhere you want a touch of whimsy.
This variety typically begins flowering in mid to late summer (around July) and will continue producing blooms right through to the first autumn frost. With proper care, the plant can produce an impressive number of flowers over the season.
Kenora Valentine Dahlia, Large Decorative
Love is in the air with this one! It’s hard to walk past this red beauty without being completely blown away. Not many gardens feature large dahlias like this, and Kenora Valentine is a true show-stopper — demanding attention and admiration. The vibrant red blooms practically pop against the lush green foliage, making it a striking focal point in any border or cutting garden.
Kenora Valentine has a long and spectacular flowering season, making it a standout in any garden. It typically starts blooming in mid-summer (around July) and continues producing large, vibrant red flowers until the first autumn frost.
I certainly underestimated how big this variety grows! I’m 5’3”, yet this plant towered over me. With those huge flower heads, it quickly becomes top-heavy, so strong staking is essential to prevent it from toppling. Something I learned the hard way. I will admit, Kenora Valentine isn’t the longest-lasting cut flower. The large blooms tend to wilt quickly once cut, so it’s not ideal for vases. However, in the garden, it is absolutely stunning. Even better, place it along a fence — not only will it make your garden pop, but it’s a cheeky way to block the view of any nosy neighbours!
Harpist’s Perfect Dahlia, Fimbriata Variety
These lovely flowers have distinctive fringed petals that give each bloom a lace like, delicate appearance. The flowers have a soft, romantic quality, often in pale pinks, creams, or gentle hues making them feel like a living piece of garden art. A must have !
Midnight Star Dahlia, Single Orchid Variety
Another work of art, a striking, two-toned bloom with single, star-shaped flowers. The petals are usually pale pink, with deep purple or maroon accents on the reverse, creating a dramatic, almost celestial effect. This is a just a nice flower. Simple as that.
