Other info. - This attractive species has not yet been recorded from wild areas in Missouri. However, it is frequently cultivated, often as a component of wildflower mixes, and it has been found in bordering states, so is not unlikely to make an appearance in Missouri at some point. Beyond Missouri it is found in scattered locations across the continental U.S. The plant's appearance is similar to large-flowered species of Cerastium. However, the flowers contain two styles instead of the five usually found in Cerastium, and the foliage is usually both glabrous and glaucous. The lower leaves clasp the stem. Under favorable conditions later in the season, these plants can produce a showy profusion of blooms.
