While the plants are horizontal at the base, their branchlets are ascending and densely covered with bristles. The leaves have petioles, which are anything between 1 cm and 4.5 cm in length. The petioles are compactly pubescent, while the blades are plump. The shape of the leaves varies from roughly ovate to rhombic, sub-orbicular or kidney-shaped to rounded to truncate and afterward usually long and slender at their base, while being thick or curved at the apex. Along the margin, the leaves are roughly crenate (having notched or scalloped margins in order to form rounded teeth) to dentate (tooth-like projections) or complete near the base. The leaves are closely pressed (appressed) as well as pubescent both above as well as beneath.

The vericils number about 10 to 20 and they are open, sub-globose and arranged in the terminals. The inflorescences are densely pubescent and about 10 cm to 20 cm in length, while the bracts are anything between 3 mm and 4 mm long. The pedicels are thin, hairy and measure about 5 mm in length. The calyx is campanulate, measuring about 1.5 mm to 4 mm in length. The calyx is hairy and glandular, with the higher lip being straight, and generally ovate or oblong shaped. The other teeth are thin and acute. The color of the corolla varies from light blue or mauve (light purple) to pink and measures about 8 mm to 12 mm in length. The corolla is tubular and expands distally. The upper lip is erect and puberulent and measures 4.5 mm x 3 mm, while the lower lip is concave and measures about 5 - 6 mm x 4 mm. The stamens appear as filaments that are generally merged into a tube around the style. The nutlets are smooth, light brown in color and measure about 0.7 mm x 0.5 mm.

Habitat and cultivation

Cuban oregano grows effortlessly, provided the soil is well-drained and the plants are grown in a partial shade. Plants of this species grow excellently in places having tropical and sub-tropical climatic conditions. They also do well when grown in cooler locations, especially if grown in containers and moved indoors or transferred to a sheltered place during the winter months. However, this herb is extremely susceptible to frost. It is important that you only water the plants moderately.

Cuban oregano variety having plain green leaves grows best when they are cultivated in partial shade, while the color of the variegated type or "Variegatus' seems to be more prominent when grown in complete sunlight or semi-shade. Provided the plants are cultivated in a sheltered place, the spreading partially horizontal stems of Cuban oregano are able to grow randomly and freely over the ground forming an excellent ground cover. In such conditions, this sprawling plant will possibly even run over small shrubs.

On the other hand, it has been found that when the common green leaf form is grown in complete sunlight, the plans show sun stress and this may result in the leaves becoming pale and rather bleached. Contrarily, the variegated variety of Cuban oregano turns out to be denser having comparatively short internodes and having compact and chunky leaves. The red tint of the leaves also becomes more vivid, particularly when the plants are grown in a comparatively arid season.
