A member of the mint family, Conradina grandiflora is a perennial, evergreen shrub endemic to Florida. It grows to 1 - 1.5 m (3.3 - 5.0 feet) in height and has grayish bark along the woody portions of the stems. Branches are typically arching or spreading in habit. The aromatic leaves are needle-like and opposite, measuring 1 - 1.5 cm (0.4 - .6 inches) in length. Upper parts of the leaves are dark green, shiny, and marked with small black dots. The lower leaf surfaces may appear white or gray in color due to a dense growth of fine hairs along the stem and leaves (Nelson 1996). Blooming occurs throughout the year. Stalked flowers appear on cymes in groups of 1 - 12. Flowers are two-lipped and large, measuring approximately 2 cm (0.8 inches) at the upper lip (Nelson 1996). There are 4 stamens that arch to the upper lip of the flower. Anthers lack horns (Wunderlin 1982; Small 1993), and the calyx is somewhat bent.Flower color is bright blue to lavender, with the lower lip flecked with tiny dark spots. Fruits are small and nut-like, with a smooth skin and dark blue-black color (Nelson 1996).
