If you’re passionate about native gardening and love discovering lesser-known plants, King’s plateau sandwort (Arenaria kingii plateauensis) might just pique your interest. This charming perennial herb is one of Utah’s native treasures, though it’s not exactly what you’d call a household name in gardening circles.
What Exactly Is King’s Plateau Sandwort?
King’s plateau sandwort is a native perennial forb that belongs to the carnation family. As a forb, it’s an herbaceous plant without woody stems—think of it as nature’s way of creating a soft, non-woody perennial that returns year after year. This particular variety is scientifically known as Arenaria kingii plateauensis, with synonyms including Arenaria kingii var. plateauensis.
Where Does It Call Home?
This native beauty is endemic to Utah, making it a true local specialty for Beehive State gardeners. Its limited geographical distribution means you’re working with a plant that’s perfectly adapted to Utah’s unique growing conditions.
Should You Plant King’s Plateau Sandwort?
Here’s where things get a bit tricky. While this native plant has obvious appeal for gardeners who prioritize indigenous species, there’s limited information available about its specific growing requirements, appearance, and garden performance. This scarcity of cultivation information suggests it’s either:

A Word of Caution
Given the limited distribution and sparse cultivation information for this plant, it may have conservation concerns. If you’re interested in growing King’s plateau sandwort, it’s crucial to source it only from reputable native plant nurseries that use responsibly collected or propagated material. Never collect plants from the wild.
