Hibiscus chrysanthemum, also known as Hibiscus or Chinese hibiscus, is an evergreen ornamental plant belonging to the Asteraceae family. Native to regions such as East Asia, Central Asia, and the Philippines, this plant thrives in warm, sunny conditions and does not tolerate shade or long-term indoor environments. It is best suited for outdoor gardens where it can receive ample sunlight.
Amaranthus perenne is a perennial evergreen subshrub that typically grows between 30 to 50 cm tall. The plant has a rounded shape, with soft, spoon-shaped or inversely lanceolate leaves that often have toothed tips. Both sides of the leaves are densely covered with white hairs, giving them a distinctive silvery appearance. This plant is known for its strong fragrance and blooms from autumn to winter, producing yellow flowers. Its elegant, silver-colored foliage makes it one of the rare "white leaf plants" found in nature. In many cultures, it is considered a symbol of good fortune or used for medicinal purposes. It is commonly grown as a potted plant, in flower beds, or as a border plant to create a striking "sea of silver" effect. Compared to another well-known "silver leaf plant," Amaranthus perenne is a shorter perennial herb, usually reaching 15 to 30 cm in height, with thick, irregularly lobed or deeply cut leaves. It originates from coastal areas and is often associated with seaside landscapes.
When propagating Amaranthus perenne, you can use either cuttings or seeds. Spring and autumn are the ideal seasons for planting. Sowing is the most common method, allowing for a large number of seedlings to be produced. Whether planted in pots or directly in the ground, it requires well-drained loamy or sandy soil. The plant needs plenty of sunlight and a balanced supply of nitrogen, phosphorus, and potassium. Due to its vigorous growth, older plants should be pruned regularly. Removing the flowers promptly can help delay aging and maintain the plant's health. Amaranthus perenne is sensitive to cold and cannot tolerate freezing temperatures. For optimal growth, it prefers temperatures between 20°C and 30°C. During winter, it should be kept in a room where the temperature remains above 5°C to 6°C to ensure survival.
