Herbs perennial. Plants 30-40 cm tall, sessile or short, tuber or elongated rhizome, sometimes thickened and woody. Leaves basal, elliptic-lanceolate, acuminate at both ends, veins conspicuous, petiole long, dark green, sheathed at the base, entire or divided.

Spring-summer flowering, scape erect, rising above the foliage, spathe erect upward, large and prominent, slightly curled, white or greenish, spikelets terete, milky yellow. Large species, dark leaves, small white flowers, slow-growing. Flowering May-August.

Distribution Range

Peace Lily is native to tropical America and widely cultivated around the world.

Growth Habit

Like high temperature and high humidity, but also more shade tolerance. Peace Lily has large leaves and is sensitive to humidity. It is afraid of exposure to strong light and enjoys 60-70% shade in summer. However, it is difficult for Peace Lily to blossom if there is insufficient light for a long time. The soil is fertile and humus-rich loam. The optimum temperature for growth is 22-28℃, 24-30℃ from March to September, and 18-21℃ from September to March of the next year. The winter temperature is not less than 14℃, and the plant growth is hindered when the temperature is lower than 10℃, and leaves are vulnerable to freezing damage. During storage and transportation, the temperature of the potted Peace Lily should be controlled at 13-16℃ and the relative humidity should be 80-90%, which can withstand the dark environment for 30 days.

Propagation Mode

Division Propagation

May and June are the best time for Peace Lily ramet propagation. The whole plant should be taken out of the pot, and the roots and stems should be cut from the base of the plant cluster. Each cluster should have at least 4 leaves.

Sowing Seeds

After flowering, Peace Lily can obtain seeds by artificial pollination. After seed collection, it needs to be sown immediately, and the germination temperature is 30℃, and it will germinate 10-15 days after sowing. If the temperature is too low when germinating, the seeds are perishable. After disinfection, callus and adventitious buds grew 45 days later.

Tissue Culture

After disinfection, the young inflorescence and lateral buds of Peace Lily were inoculated on MS medium supplemented with 10 mg/L 6-Beniamino-adenine and 2 mg/l indoleacetic acid. After 40-45 days, callus and adventitious buds grew, and then adventitious buds were transferred to MS medium supplemented with 2 mg/l indoleacetic acids, and rooting was induced in 30-40 days. Become a whole plant.

Cultivation Techniques

The Main Technical Points

Prevention and Control of Diseases and Pests

Peace Lily is the most popular insect pest during the growth period, and special insecticides of mites should be sprayed regularly for control, such as dicofol, solon, and pyridoxine.

The Main Value

Ornamental Value

Peace Lily can be potted or planted in clusters and rows on flower beds, shaded spots of gardens, stone groups, and edges of pools to play a greening role. Peace Lily flower stems are straight and beautiful. Potted plants adorn the living room and study, which are very comfortable and chic, elegant and beautiful. In the south, configuration small garden, poolside, corner place, have a unique style. In addition, the flowers of Peace Lily are also excellent decorative materials for flower baskets and flower arrangements.

Purify Air

The Peace Lily can filter indoor exhaust gas and has some effectiveness against ammonia, acetone, benzene, and formaldehyde. Peace Lily cultivated with water root can regulate indoor temperature and humidity through evocation, and can effectively purify volatile organic compounds in the air, such as alcohol, acetone, trichloroethylene, benzene, toluene, chlorine monoxide, ozone, etc. Especially for ozone purification rate is particularly high, placed next to kitchen gas, can purify the air, remove the cooking smell, lampblack, and volatile substances.
