Trachelospermum jasminoides is a perennial evergreen woody vine in the Apocynaceae family. Its stem is reddish-brown, and its young branches are covered with long yellowish fuzz and have aerial roots.

It often climbs and grows on trees and stone walls. Star Jasmine prefers semi-shade and moist environments, but it is also drought and wet tolerant. It is not particular about soil conditions, although it prefers well-drained sandy loam.

It is often used as ground cover in gardens. However, it is a poisonous plant, with all parts of it being toxic. Its symptoms are similar to those of the poisonous fruit of the sea mango.

I. Morphological Features

Trachelospermum jasminoides

Star Jasmine is an evergreen woody vine that can grow up to 10 meters long and exudes a milky sap. Its stem is reddish-brown and cylindrical with lenticels. Young branches are fuzzy and yellow, but as they mature, they lose their fuzz.

The leaves are leathery or nearly so, oval to ovate or wide-ovate, 2-10 cm long and 1-4.5 cm wide. The leaf apex is acute to acuminate or obtuse, sometimes slightly concave or with a small protruding tip.

The base of the leaf gradually narrows to a blunt point. The top of the leaf is hairless, while the underside is sparsely covered with short fuzz, which disappears as the leaf ages. The leaf veins are slightly concave on the top and flat on the bottom.

There are 6-12 lateral veins on each side of the leaf, which are flat or slightly protruding. The leaf stalk is short, covered with short fuzz, and becomes hairless as it ages. The inner part of the leaf stalk and the outer part of the leaf axil have diamond-shaped glands, about 1 mm long.

The flowers are borne on dichotomous umbel inflorescences that are axillary or terminal, forming conical clusters that are as long or longer than the leaves. The flowers are white and fragrant.

The peduncle is 2-5 cm long, covered with fuzz, and loses its hair as it ages. The bracts and bracteoles are narrowly lanceolate, 1-2 mm long.

The calyx is deeply divided into five segments, which are linear-lanceolate, with the tips curled backwards, 2-5 mm long, covered with long soft hairs and marginal hairs on the outside, and hairless on the inside.

There are ten scale-like glands at the base. The bud apex is blunt. The corolla tube is cylindrical, enlarged in the middle, hairless on the outside, and covered with short fuzz at the throat and where the stamens are attached, 5-10 mm long.

The corolla lobes are 5-10 mm long and hairless. The stamens are attached in the middle of the corolla tube, and their backs are attached to the stigma. The anthers are arrow-shaped, with ears at the base, and hidden inside the corolla throat.

The disc is ring-shaped and divided into five segments, the same length as the ovary. The ovary is composed of two separate carpels, hairless.

The style is cylindrical, and the stigma is ovate, with a complete margin at the top. Each carpel has many ovules, which are attached to two parallel placenta.

The follicles are borne in pairs, spread out, hairless, linear-lanceolate, tapering towards the apex, 10-20 cm long and 3-10 mm wide.

The seeds are numerous, brown, linear, 1.5-2 cm long and about 2 mm in diameter, with white silky seed hairs at the apex. The seed hairs are 1.5-3 cm long. It flowers from March to July and fruits from July to December.

II. Growth Environment

This plant is highly adaptable to various climates, tolerating both cold and heat, but not severe cold. It prefers weak light and can withstand strong sunlight and high temperatures. It can grow on both sunny and shady walls.

The plant is not demanding about the type of soil it grows in. Moderate fertility loamy and sandy soil are suitable, as well as acidic and alkaline soils. It is drought-resistant but dislikes overly damp conditions. For potted plants, avoid overwatering and keep the soil moist.

It naturally grows in the wild, by streams, roadsides, forest edges, or mixed forests, often entwined around trees or climbing on walls and rocks. It can also be transplanted to gardens.

III. Distribution Range

It can be found in Japan, Korea, and Vietnam.

IV. Growth and Reproduction

The preferred method of propagating this plant is by layering, especially during the rainy season when its tender stems easily grow aerial roots. Utilizing this characteristic, the tender stems can be propagated using the continuous layering method.

In the autumn, cut the stems from the middle to yield numerous seedlings. Alternatively, during the rainy season, cut the tender stems with aerial roots and insert them into plain soil placed in a semi-shaded area.

The survival rate is high, but the survival rate of old stem cuttings is low. After flowering, potted plants generally do not produce seeds, but ground-grown plants can produce cylindrical fruits.

After harvesting in October, seeds can be sown the following spring. However, seedlings take three to four years to flower, while layered or cut plants can flower the following year, so sowing is not commonly used.

For potted plants, besides the general methods, it can also be grown by hanging or climbing due to its own characteristics.

When using aerial roots for climbing, you can first place a coir column or a well-shaped dead tree trunk in the pot, and tie it into pavilions, towers, flower baskets and other shapes.

Maintenance is simple; water to keep the soil moist and frequently spray water onto the coir column or support to increase humidity. During the growing period, apply fertilizer water 1-2 times a month and avoid direct sunlight.

It is best to expose it to semi-shade or scattered light. Propagation during the growing season is easy to survive using both cutting and layering methods.
