Heal-all or self-heal (Prunella vulgaris) is a native herbaceous perennial in the Lamiaceae. Other common names include woundwort, heart-of-the-earth, carpenter's herb, brownwort and blue curls. The pubescent and branched stems are square in cross-section. The inflorescence is a terminal spike. The leaves are opposite, simple, and have pinnate major veins. The flowers are perfect and irregular, with five two-lipped sepals, five petals, and four stamens. The five violet to white petals are two-lipped, with two petals in the upper lip and three in the lower lip. The four-lobed ovary is superior, and the style arises between the lobes. The fruit is a schizocarp with four mericarps.  Heal-all is a common roadside plant, with reports from almost all parishes. It flowers from April to June.  It is usually in the same habitat as lyre leaf sage and flowers about a month after the sage.  An edible and medicinal plant that has a Worldwide distribution.  Quite a bit in fallow areas on Allen Acres.
