Periwinkle is one of those plants people often take for granted.
You’ll see it spilling over borders, creeping beneath shrubs, or quietly covering awkward patches of ground — and most gardeners barely give it a second glance.
But this tough little evergreen is far more than just a simple ground cover.
Known scientifically as Vinca, periwinkle has been admired for centuries not only for its beautiful flowers, but also for its fascinating history, resilience, and surprisingly important role in modern medicine.
Once you learn more about it, you start to realise this is a plant with far more going on beneath the surface.
Why Gardeners Love Periwinkle
One of the biggest reasons periwinkle remains so popular is because it’s incredibly easy to grow.
It happily spreads through difficult areas where many other plants struggle, making it perfect for:
- Shady borders
- Sloped gardens
- Under trees and shrubs
- Difficult dry spots
- Low-maintenance ground cover
Its glossy evergreen leaves provide year-round interest, while the soft blue-purple flowers add a lovely splash of colour through spring and summer.
And honestly, once it establishes itself, it practically looks after itself.
That’s a huge win for busy gardeners.
A Plant With a Long History
Periwinkle has been valued for hundreds of years.
Historically, it was used in traditional remedies and was even associated with protection and folklore in some cultures. Ancient Greeks and Romans reportedly used the plant in various herbal practices long before modern science began studying its compounds.
Of course, these days most gardeners simply grow it because it’s attractive, reliable, and excellent at filling empty spaces.
But its historical background definitely makes it a more interesting plant than many people realise.
The Surprising Science Behind Periwinkle
This is where things become particularly fascinating.
Periwinkle contains naturally occurring compounds called alkaloids, including vincamine and vincristine, which scientists have studied extensively for medical use.
In fact, some compounds derived from periwinkle have played an important role in modern medicine, particularly in treatments developed for certain cancers.
That’s a pretty incredible legacy for a plant many people simply treat as decorative ground cover.
It’s one of those reminders that plants growing quietly in our gardens can sometimes hold far more significance than we ever imagined.
But There’s Something Important to Know
While periwinkle has a fascinating medicinal history, it’s important not to experiment with consuming plants yourself.
Many medicinal plants can also be toxic if used incorrectly, and periwinkle is no exception.
I’d always recommend appreciating it as a garden plant unless you’re working with properly qualified medical or herbal guidance.
From a gardening perspective though, it’s hard not to admire just how versatile and resilient this plant really is.
A Brilliant Low-Maintenance Option
If you’re trying to reduce maintenance in your garden, periwinkle is genuinely worth considering.
It spreads quickly, suppresses weeds surprisingly well, and handles both sun and partial shade with ease.
That creeping growth habit also makes it useful for preventing soil erosion on banks and slopes.
And unlike many fussy flowering plants, it doesn’t demand constant feeding, pruning, or attention.
Sometimes the best plants are the ones that quietly get on with the job.
Clive’s Tips
- Periwinkle is fantastic for filling awkward bare patches beneath trees and shrubs.
- If you want fast ground cover, plant several small plants about 12 inches apart and let them spread naturally.
- Trim it back once or twice a year to keep it looking tidy and prevent it from becoming too invasive.
- The blue and purple flowers look especially beautiful alongside spring bulbs and ferns.
- Don’t underestimate simple plants — some of the toughest and most useful garden plants are often the most overlooked.
