Heliotropium peruvianum

Stem: This herbaceous plant grows about 50 centimeters tall, with an erect or ascending stem. The base becomes woody, with the upper stem densely covered in yellow short appressed hairs and sparse, stiff hairs.

Leaves: Lower stem leaves have long petioles, while middle and upper leaves have short petioles. The leaf blades are ovate or oblong-lanceolate, 4-8 centimeters long, and 1.5-4 centimeters wide.

The tips taper to a point, and the bases are broadly cuneate. The upper surfaces are rough, with stiff hairs and appressed hairs, while the undersides are soft and densely hairy.

There are 8-9 pairs of prominent lateral veins on both surfaces. Leaf petioles are 0.5-1.5 centimeters long, densely covered with stiff and appressed hairs.

Flowers: The scythe-shaped corymb inflorescences are terminal, forming into umbel-like clusters during the dense flowering season. They have a diameter of 4-6 centimeters, expanding to about 10 centimeters after blooming.

The flowers are sessile or rarely have short stalks. The calyx is 0.5-0.25 centimeters long, split to below the middle, with sparse short stiff hairs on the outside and glabrous or sparsely appressed hairy on the inside above the middle.

The lobes are lanceolate and vary in size. The corolla is violet or purple, occasionally white, fragrant, 0.3-0.6 centimeters long, with a base diameter of about 0.1 centimeter.

The limb diameter is 0.5-0.7 centimeters, with short appressed hairs on the midrib and throat on the outside, and glabrous on the inside. The anthers are ovate-oblong, 0.12-0.15 centimeters long, with very short filaments attached just above the base of the corolla tube.

The ovary is globose and glabrous, with a distinct style about 0.05 centimeters long, and the stigma slightly longer than the style. The sterile part is conical, about 0.05 centimeters long, with the fertile part being disc-shaped. The flowering period is from February to June.

Fruit: The fruit is a drupe, globose and glabrous, splitting into four single-seeded mericarps upon maturity.

II. Characteristics

Perennial herbaceous plants grow to about 50 centimeters tall, with erect or ascending stems that become woody at the base. These stems are either unbranched or densely branched in the upper part, covered with yellow short appressed hairs and sparse stiff hairs.

The leaves are arranged alternately with short petioles, ranging from ovate to lanceolate in shape, with entire margins and a rough surface.

There are 7 to 8 pairs of veins, both main and lateral, that are recessed, giving the leaf surface a wrinkled appearance, and the underside is covered with white tomentose hairs. The plant features terminal corymbs with small flowers.

The calyx is equal in length to the floral tube; the corolla is five-lobed, funnel-shaped, with short, broad lobes that flare outward. The flowers are violet or purple, exuding a distinctive fragrance.

The drupe is spherical and hairless, splitting into four single-seeded mericarps when mature. The blooming period is from February to June. Notable ornamental varieties include the large-flowered and European scented verbena.

Propagation is typically done through cuttings, although sowing is also possible. However, obtaining seeds can be challenging in greenhouse cultivation.

Scented verbena is a light-loving plant requiring ample sunlight. In insufficient light, the plant may grow weak with thin branches, small flowers, or fail to bloom at all.
