Sandwort Drymary: A Plant to Avoid in Your Garden
When it comes to choosing plants for your garden, not every species deserves a spot in your landscape. Meet sandwort drymary (Drymaria arenarioides), a small herbaceous plant that might seem innocuous at first glance, but carries a significant warning label for gardeners across the United States.

What is Sandwort Drymary?
Sandwort drymary is a forb – essentially a soft-stemmed plant without woody tissue that stays close to the ground. Like other members of its family, it’s an herbaceous plant that lacks the thick, woody stems you’d find on shrubs or trees. Instead, it keeps its growing points right at or below ground level, making it a persistent presence once established.
The Big Red Flag: Noxious Weed Status
Here’s where things get serious: sandwort drymary is classified as a noxious weed in the United States. This isn’t just a casual designation – it means this plant poses a real threat to local ecosystems, agriculture, or native plant communities. When a plant earns noxious status, it’s essentially getting a do not plant warning from agricultural and environmental authorities.
Why You Should Skip This Plant
As tempting as it might be to experiment with different species in your garden, sandwort drymary falls firmly in the avoid category. Here’s why:
- Its noxious weed status means it can harm local ecosystems
- It may outcompete beneficial native plants
- Growing it could potentially spread seeds to natural areas
- You might face legal restrictions on cultivating noxious weeds in your area
Geographic Concerns
While specific distribution information for sandwort drymary is limited, its noxious designation suggests it has already caused problems in areas where it’s established. The plant’s scientific name hints at its preference for sandy conditions – arenarioides means sand-like – suggesting it might thrive in well-drained, sandy soils.
Better Alternatives for Your Garden
Instead of risking the ecological consequences of planting sandwort drymary, consider these native alternatives that can provide similar aesthetic appeal without the environmental concerns:
- Native sandworts (Arenaria species) that are actually native to your region
- Local wildflowers with small, delicate blooms
- Regional ground covers that support local wildlife
- Consult your local native plant society for specific recommendations
The Bottom Line
When it comes to sandwort drymary, the message is clear: this is one plant that’s better left out of your garden entirely. Its noxious weed status isn’t just bureaucratic red tape – it’s a genuine warning about a plant that can cause real ecological harm.
Instead of taking risks with problematic species, focus your gardening energy on native plants that will support local wildlife, require less maintenance, and contribute positively to your local ecosystem. Your garden – and your local environment – will thank you for making the responsible choice.
Remember: the best gardens work with nature, not against it. Choose plants that belong in your region, and you’ll create a landscape that’s both beautiful and beneficial for years to come.
