Caucasian Stonecrop: A Hardy Ground Cover with Non-Native Origins
If you’re looking for a tough, low-maintenance ground cover that can handle challenging conditions, Caucasian stonecrop (Phedimus spurius t) might catch your eye. This succulent perennial has made itself at home across North America, though it originally hails from elsewhere. Let’s dive into what makes this plant tick and whether it deserves a spot in your garden.
What is Caucasian Stonecrop?
Caucasian stonecrop goes by the botanical name Phedimus spurius t, though you might also see it listed under its former names like Sedum spurium. This hardy succulent belongs to the stonecrop family and has earned a reputation as a reliable, if somewhat aggressive, ground cover option.
Native Status: A Traveler That’s Made Itself at Home
Here’s something important to know upfront: Caucasian stonecrop isn’t a North American native. This plant species has been introduced to our continent and now reproduces on its own in the wild, persisting without any human help across both Canada and the lower 48 states. While it’s not necessarily problematic, this non-native status is worth considering when planning your garden.
Where You’ll Find It Growing
Caucasian stonecrop has established itself across a impressive range of locations, including Nova Scotia, Ontario, Quebec, Northwest Territories, and Newfoundland in Canada. In the United States, you can find it growing in Colorado, Connecticut, Illinois, Indiana, Maine, Massachusetts, Michigan, New Jersey, New York, Oregon, Pennsylvania, Vermont, and Washington.
Should You Plant Caucasian Stonecrop?
This is where things get a bit nuanced. On one hand, Caucasian stonecrop is undeniably tough and can solve problems in challenging garden spots. On the other hand, its non-native status means it won’t provide the same ecological benefits as native alternatives.
Reasons you might consider it:
- Extremely hardy and low-maintenance
- Excellent for areas where other plants struggle
- Forms dense mats that suppress weeds
- Tolerates poor soil conditions
Reasons to think twice:
- Non-native status means limited wildlife value
- Can spread aggressively and potentially escape cultivation
- May outcompete native plant species
Native Alternatives to Consider
Before settling on Caucasian stonecrop, consider these native ground cover options that provide similar benefits while supporting local ecosystems:
- Wild ginger (Asarum canadense) for shaded areas
- Creeping phlox (Phlox subulata) for sunny slopes
- Kinnikinnick (Arctostaphylos uva-ursi) for acidic soils
- Native sedums like Sedum ternatum (woodland stonecrop)
Growing Caucasian Stonecrop Successfully
If you do decide to grow Caucasian stonecrop, here’s what you need to know to keep it happy and contained:
Growing Conditions: Like most stonecrops, this plant thrives in well-draining soil and full sun to partial shade. It’s remarkably tolerant of poor, rocky, or sandy soils where other plants might struggle.
Planting Tips: Space plants appropriately and consider installing root barriers if you’re concerned about spread. Plant in spring or early fall for best establishment.
Care Requirements: Once established, Caucasian stonecrop requires minimal care. Water sparingly, as overwatering can lead to root rot. Trim back after flowering to maintain a tidy appearance.
The Bottom Line
Caucasian stonecrop is undeniably useful for challenging garden situations, but its non-native status gives us pause. While we can’t definitively say it’s problematic in all situations, choosing native alternatives whenever possible supports local ecosystems and wildlife. If you do choose to plant it, do so responsibly and keep an eye on its spread to prevent it from escaping into natural areas.
Remember, the best garden is one that works with nature rather than against it. Consider your local ecosystem and choose plants that contribute to the health of your regional environment whenever possible.
