The title of "World's Most Beautiful Flower" is hotly contested. Ask an orchidist, and surely they'll have a strong opinion, as will a rose enthusiast or a tulip fanatic. But at least few people believe the jade vine (Strongylodon) is a contender for the title. And if not most beautiful flower, at least one of the world's most interesting. The vines flowers are pendant, hanging in large clusters of claw-shaped flowers in a remarkable turquoise color. Jade flowers are aggressive growers that, in their natural environment, easily swallow trees and supporting structures. With this kind of aggressive growth, these are better suited for greenhouses or conservatories. But if you are able to give a jade vine the room and growing conditions it needs, you will be rewarded with a magnificent specimen plant.
Jade vine needs as much sun as possible to thrive. They prefer full sun or the filtered light of a bright greenhouse. They do not have a rest period in winder.
Jade vine is a water hog. It will grow best with ample and copious water. Lack of water will cause leaf-browning and slow and stunted growth. Water all year.
A rich, peat-based potting soil with excellent drainage is beneficial.
Feed with a weak liquid fertilizer
throughout the growing season.
Jade vine can be propagated by seed or vine cuttings. They are very prolific growers and can by rooted from stem tip cuttings. For best results, take the cuttings early in the season, when the weather is warmest, and use a rooting hormone. Place the cutting in seedling starting soil and put it in a warm location with plenty of humidity and moisture. New growth should emerge within a few weeks. They can also readily be sprouted from seeds, which can be harvested from seedpods.
As with most vines, repotting a jade vine indoors can be a challenge. Ideally, the plant will be grown in the largest container possible, to minimize the need to repot (this is the approach many indoor growers take). Once the vine is established, instead of repotting, change the surface soil once a year or so by scrapping out old soil and replacing the top few inches of soil. Smaller plants, before they become climbers, can be repotted annually.
There are about 20 species of Strongylodon, all of them native to southeast Asia and throughout the South Pacific. In their native environment, many species of Strongylodon are endangered due to habitat destruction, so there is a dedicated effort among the world's botanical gardens to preserve these magnificent plants. The most common species found in cultivation in the temperate world is S. macrobotrys, which is planted in southern Florida and Hawaii. This plant is native to the Philippines and features flower clusters that can be up to 3 feet long.
The trick with jade vines is usually more: more heat, more light, more light, and more fertilizer. Because jade vines grow rapidly and have pendant flowers, be sure to provide them with a sturdy support. Ideally, the flowers are best viewed from underneath, but the plants can also be grown up a vertical structure and the flower clusters will hang down among the leaves as bright splashes of color. Jade vines are not particularly susceptible to pests, but can be affected by mealybugs
, and mites. Signs of infestation include tiny webs on plants, clumps of white "powdery" residue, or visible insects on the plant. Treat infestations as soon as possible to prevent them from spreading to the rest of your collection.
