Description
Origin
Jiaogulan, also known as the “herb of immortality,” is a herbaceous plant from the Cucurbitaceae family, native to the mountainous regions of Southeast Asia, particularly in China, Japan, and Vietnam. It has been consumed for centuries in traditional Chinese medicine and as tea.
Growth, Appearance, and Characteristics
It is a perennial climbing plant with heart-shaped leaves that grow in clusters of five to seven leaves, hence the scientific name “pentaphyllum,” which means “five-leaved.” The leaves are deep green and have a leathery texture. The plant produces small green flowers arranged in dense clusters.
Cultivation and Care
Jiaogulan grows best in well-draining soil and prefers a semi-shaded to sunny location. The plant requires regular watering and can be fertilized in spring with a balanced fertilizer to promote growth. It can be propagated either from seeds or by cuttings and should be regularly pruned to control excess growth.
Taste and Use
The leaves have a mild, slightly sweet taste reminiscent of green tea. They can be used fresh or dried to prepare tea, which can be enjoyed hot or cold. Jiaogulan tea is often consumed for its health benefits, including promoting relaxation, endurance, and a healthy immune system.
Harvest Time
The leaves can be harvested throughout the year once the plant has grown sufficiently. The first leaves can typically be harvested about 3 to 6 months after planting. The leaves are best harvested in the early morning when the content of valuable nutrients is highest.
Pollination The flowers are pollinated by bees and other insects. Pollination occurs through the transfer of pollen from the stamens to the pistils of the flowers. This process allows for the fertilization of the flowers and the formation of seeds, which contribute to the plant’s reproduction.
