Snow-on-the-mountain is an annual forb distinguishable for its oval green leaves with striking white margins, creating a 'frosted' appearance likened to snow cover. It stands erect reaching heights of up to 3 feet (90 cm). This species exhibits clusters of small, inconspicuous green flowers surrounded by showy bracts, which mistakenly appear as the true flowers. These bracts are prominent later in the season, accentuating the visual contrast with the foliage.
