Carolina Frostweed: A Charming Native Groundcover for Southern Gardens
If you’re looking for a low-maintenance native plant that brings sunny cheerfulness to your garden, meet Carolina frostweed (Helianthemum carolinianum). This delightful little perennial might not be the showiest plant in the garden center, but it’s a true gem for gardeners who appreciate native plants that actually belong in their landscape.
What Makes Carolina Frostweed Special?
Carolina frostweed is a native forb – basically a non-woody perennial that hugs the ground and spreads to form a lovely natural carpet. Don’t let its humble appearance fool you; this plant has been thriving in the southeastern United States long before any of us started worrying about what to plant in our gardens.
You might also see this plant listed under its scientific synonym, Crocanthemum carolinianum, but don’t let the fancy names intimidate you. It’s the same cheerful little groundcover either way.
Where Does Carolina Frostweed Call Home?
This native beauty naturally grows across the southeastern states, including Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina, South Carolina, and Texas. It’s particularly fond of the sandy soils found in coastal plains and pine woodlands throughout this region.
