The propagation and maintenance of Crinum asiaticum
Today's focus is on introducing the experience of growing the Crinum asiaticum, a plant from the Orchidaceae family. Let's take a look at the propagation and maintenance of Crinum asiaticum together!
Crinum asiaticum has a robust plant structure and elegant fragrance, making it a large potted flower for decorating halls and venues. Also known as "Eighteen Scholars," "Wen Zhu Lan," and "White Flower Stone Garlic," it belongs to the Amaryllidaceae family, Crinum genus, and is a perennial evergreen herb. It has a scaly bulb, long and cylindrical in shape. The leaves are basally sword-shaped, densely arranged in a rosette pattern at the top of the bulb, with wavy edges. The plant is about 1 meter tall. The flower scape emerges from the leaf cluster, with an umbel inflorescence, covered by two large bracts, and has over 20 flowers. The flower tube is thin, long, and upright, with a fragrant scent. The blooming period is usually in summer, and it can bloom continuously throughout the year under conditions of sufficient water and fertilizer and moderate temperature and humidity.

There are about 100 species in the genus, and some commonly cultivated ornamental ones include: Crinum asiaticum var. rubrum, with a white or light pink inner surface of the flower tube and a purple outer surface, native to Sumatra. Crinum asiaticum var. album, with strap-shaped, leathery, bright green leaves, white flowers, native to South Africa. Crinum asiaticum var. luteum, with flower scapes about 70 cm tall and usually 4 flowers, native to North America. Crinum asiaticum var. southwest, with high-footed saucer-shaped flowers, white with red blush, native to Yunnan, Guangxi, and Guizhou in China, as well as Vietnam, India, and Malaysia, growing on riverbed sandy soils. Crinum asiaticum is native to the tropical regions of Asia, and there is wild growth on Hainan Island in China.
Crinum asiaticum prefers warm, fresh, and humid air. It dislikes intense sun exposure during high temperatures and requires sufficient light at medium and low temperatures. The optimal growth temperature is between 18°C and 22°C, and the indoor temperature during winter should not be lower than 5°C. The potted plants thrive in sandy loam soil rich in humus content, loose and fertile, with good permeability. Plants of the Crinum genus are mostly distributed in coastal areas of tropical and subtropical regions, so they are relatively salt-tolerant.
Crinum asiaticum is usually propagated by seeding and dividing. Seeding should be done immediately after harvesting, using sandy loam soil as the substrate, maintaining a temperature of 20°C to 25°C, which takes about 2 weeks to germinate and requires 3 to 4 years of care to bloom. Since seeds are not easily matured in greenhouse potted conditions and some do not bear fruit, such as Crinum asiaticum var. rubrum, propagation is usually done by dividing. In spring or late autumn, combine the potting operation with dividing the suckers around the mother plant, taking care not to damage the roots and planting them separately. Most suckers do not have roots and need to be handled like tender branch cuttings using plain sandy soil or vermiculite in a warm, shaded, and humid environment, which takes about 1 month to root. After the cuttings have rooted and survived, they should be planted in small pots using ordinary potting soil. The cuttings should not be planted too shallowly, just enough not to see the bulb, and then each year, use enriched potting soil, adding some crushed hoof or bone meal as long-acting fertilizer, and transfer to a larger pot for care. Crinum asiaticum has a strong root system and grows rapidly, requiring sufficient water and fertilizer during the growing season, keeping the potting soil and surrounding environment warm and moist, and preventing waterlogging, with liquid fertilizer applied every two weeks.
If the potting soil has a high humus content, it is advisable to use a compound fertilizer solution to protect the environment. After autumn, bring the plant indoors to hibernate at around 10°C, and during the dormant period, water and fertilizer should be controlled. In late April, take the plant out of the room and place it in a windproof and rainproof shade house. For home cultivation, it can be placed on a north-facing balcony or the back of a south-facing balcony, or can be displayed indoors for an extended period, with attention to air circulation and avoiding smoke and dust pollution. It does not grow well in air-conditioned rooms.
