Cosmos caudatus, commonly known as Ulam Raja or King’s Salad, is an annual plant in the Asteraceae family. Native to Central and South America, it thrives in seasonally dry tropical climates. It is known for its feathery foliage and vibrant pink to purple flowers. The plant is often used in traditional medicine and as a culinary herb in Southeast Asia.
Cosmos caudatus is relatively easy to care for. It prefers bright, direct sunlight and moderate temperatures. Water the plant when the soil is almost completely dry, and ensure it has good air circulation. It can tolerate moderate humidity levels and does not require a dormancy period.
収穫
Cosmos caudatus, commonly known as Ulam Raja, is typically ready for harvest about 60 days after planting. The best time to harvest is in the early morning when the leaves are crisp and full of moisture. To harvest, use clean, sharp scissors or pruning shears to cut the stems just above a leaf node, which encourages new growth. Regular harvesting can promote bushier plants and more abundant foliage. Ensure that you do not remove more than one-third of the plant at a time to avoid stressing it.
