Ernest’s Spiderwort: A Rare Native Gem for Southern Gardens

If you’re a gardener who loves discovering hidden treasures in the native plant world, Ernest’s spiderwort (Tradescantia ernestiana) might just be the perfect addition to your collection. This lesser-known member of the spiderwort family brings both beauty and conservation value to gardens across the American South.

What Makes Ernest’s Spiderwort Special?

Ernest’s spiderwort is a perennial forb—basically a non-woody flowering plant that comes back year after year. Unlike shrubs or trees, this charming plant lacks significant woody tissue and keeps its growing points right at or below ground level, making it perfectly adapted to survive through different seasons.

As a true native of the lower 48 states, this spiderwort has evolved alongside local ecosystems for thousands of years. It’s naturally found across six states: Alabama, Arkansas, Mississippi, Missouri, Oklahoma, and Texas, where it has learned to thrive in the unique conditions of the southeastern and south-central regions.

A Word About Rarity (This is Important!)

Here’s where things get interesting—and a bit serious. Ernest’s spiderwort isn’t your run-of-the-mill garden plant. It has a global conservation status of S3S4Q, and in Alabama, it’s considered quite rare with an S1 status. This means if you’re lucky enough to find this plant available, you’re dealing with something pretty special.

Important note for responsible gardeners: If you decide to grow Ernest’s spiderwort, please make sure you source it responsibly from reputable native plant nurseries or conservation organizations. Never collect plants from the wild—this could harm already vulnerable populations.
