- Description
-
Rock Sandwort is a low growing, herbaceous perennial in the honeysuckle family, native to eastern Canada and the United States. In its natural setting, it can be found growing along rocky summits, woodlands, forests, ledges and rock crevices. It has a low growing habit, forming mats or dense clumps and tuffs. Small dished shaped white 5-petaled flowers grow on thin stalks as a form called hypanthium (a structure where the basal portions of the calyx (corolla) and the stamens form a cup-shaped tube that contains the nectar secreting organ). Its taproots are woody and thickened with many branches.
Rock Sandwort does best in full sun and can thrive on dry conditions on rocky or gravely soils. In the wild, it occurs often on limestone or sandstone ledges with significant sun exposure. The plant has a long tough root that enables in to grow in cracks and holes in rocky substrates. Given the nature of its native growing environment, it can be challenging to grow in the typical home garden or landscape.
Rock Sandwort has a patchy distribution in the United States and is considered endangered in many states and is listed as extinct in Delaware.
Rock Sandwort has slender, wiry, forking, stems that spread along the ground for 4 to 12 inches and form loose mats.
