Telosma Cordata: Cowslip Creeper Vine and Its Edible Flowers
A member of the milkweed family, Telosma cordata is a creeper—a twining vine that you may want to consider adding to your garden. Native to China and also known as Tonkin jasmine, it displays showy clusters of flowers that are both fragrant and edible (they are in fact used in many Asian dishes).
Tonkin jasmine can be a nice shade provider if you have this growing in a trellis in your garden area. Adding this in an entryway on an arbor doesn't just beautify the area, but it's also a nice way to enjoy the rich fragrance and the flowers produced.
Telosma cordata can creep up to 16 feet. Both the leaves and the twining vine are green, but as the plant ages, the vine turns to brown.
The green leaves are heart-shaped and pointy at the tip. Although they grow in pairs, it isn't uncommon to see four pairs of leaves on a stem. If you want your Tonkin jasmine or sabiddukong vine to creep on a certain spot, keep an eye on it. A young vine may want to explore around and climb, even on strings. The green, smooth leaves are about 2–4 inches long, with the veins visible.
The flowers usually appear in the nodes where the leaves are. They start off green, in clusters consisting of 10 to more than 30 flowers that take weeks to fully develop and open. As the flower buds develop and bloom from late spring to autumn, they change from green to yellow.
The flowers also don't all bloom at the same time but rather in bunches, and the rest of the flowers follow. As the Tonkin jasmine flower opens, it creates a five star-like shape with the five yellow petals. While the inside of each petal is a beautiful yellow, the top portion and the base are yellowish to greenish in color. Flowers of Tonkin jasmine tend to be strongly fragrant at night.

Growing Cowslip Creeper, Tonkin Jasmine, or Pakalana Vine
When it comes to growing sabiddukong or Tonkin jasmine, it is either done so from seeds or cuttings in fertile, well-drained soil where it gets enough sunlight. Water the plant generously, keeping the soil moist.
Ours started off from seeds in a container. When the weather gets cold or chilly during winter season, the vine slows in growth or becomes dormant but resumes growing when the weather gets hot. New and young shoots start showing up again during spring season. Clusters of flowers start showing up during spring to fall season. In the Philippines, it is during the rainy seasons that this vine produces flowers.
Cowslip creeper fruit is green with pointy ends. As the fruit matures, it turns brown in color, with a lot of brown seeds inside that are smooth and flat.
