Thanks to its lovely evergreen foliage, delicate blooms, and sheer toughness, Dwarf Periwinkle isn’t just a favorite for planting under trees—it’s also a go-to for brightening up shady courtyards. With *Vinca minor*, you get to enjoy a super low-maintenance groundcover that doesn’t need much hand-holding, even when the winter chill sets in.
Vinca minor: A Hardy Groundcover Hero
Dwarf Periwinkle (sometimes called Myrtle) is a gardener’s favorite because it stays green all through the winter. The best part? It doesn’t really need any special winter protection. This hardy perennial is tough enough to handle the cold on its own, provided it’s in one of its preferred locations. You might notice a few withered or dead leaves here and there during the winter months, but don’t sweat it. Just prune those back in the spring with your garden shears to make room for fresh new growth, and be sure to clear away any fallen tree leaves sitting on top of the plants.
Natural Protection for Your Other Plants
This evergreen beauty doesn’t just look good; it actually acts as a bodyguard for more sensitive shrubs and trees. In the summer, it shades the roots of its neighbors to keep them from drying out. In the winter, it acts as a natural thermal blanket, protecting the soil and roots from the biting cold.
Winter Care During Deep Freezes
Unlike some perennials that die back completely underground, *Vinca* stays above board all year. After the first few night frosts, you’ll often see the leaves take on some really cool color shifts that add a bit of life to a dormant garden. If you’re expecting a deep freeze where the ground stays frozen during the day, you can give it a little extra help. Just a heads-up: don’t use fallen tree leaves as mulch. Wet, heavy leaves can actually smother the plant. It’s better to clear that old leaf litter away so your *Vinca* can breathe.
Using Evergreen Boughs
If you want to provide cover, try using spruce or fir boughs instead. The great thing about evergreen branches is that they slowly drop their needles in the spring, which helps the *Vinca* gradually acclimate to the stronger spring sun. One quick tip: keep an eye out for mice! They love to nest under winter covers, so a quick check every now and then will keep them from making themselves too at home.
Overwintering Potted Plants
Since *Vinca minor* looks fantastic in pots and containers, you can definitely keep it outdoors if you take a few precautions. If possible, move your containers against a wall or under a roof overhang. To keep the pots from cracking and the roots from freezing solid, wrap them in burlap or garden fleece. Don’t forget that your Periwinkle still needs a little water during the winter when the soil isn’t frozen. Just be careful not to overdo it—good drainage is key to preventing root rot!
